Case studies are in-depth investigations of a person, group, event, or community. Typically, data is gathered from various sources using several methods (e.g., observations & interviews).

The case study research method originated in clinical medicine (the case history, i.e., the patient’s personal history). In psychology, case studies are often confined to the study of a particular individual.

The information is mainly biographical and relates to events in the individual’s past (i.e., retrospective), as well as to significant events that are currently occurring in his or her everyday life.

The case study is not a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.

Freud (1909a, 1909b) conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.

This makes it clear that the case study is a method that should only be used by a psychologist, therapist, or psychiatrist, i.e., someone with a professional qualification.

There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical (i.e., abnormal) behavior or atypical development.

Types of Case Studies

  • Explanatory case studies : Used to explore causation in order to find underlying principles. Helpful for doing qualitative analysis to explain presumed causal links.
  • Exploratory case studies : Used to explore situations where an intervention being evaluated has no clear set of outcomes. It helps define questions and hypotheses for future research.
  • Descriptive case studies : Describe an intervention or phenomenon and the real-life context in which it occurred. It is helpful for illustrating certain topics within an evaluation.
  • Multiple-case studies : Used to explore differences between cases and replicate findings across cases. Helpful for comparing and contrasting specific cases.
  • Intrinsic : Used to gain a better understanding of a particular case. Helpful for capturing the complexity of a single case.
  • Collective : Used to explore a general phenomenon using multiple case studies. Helpful for jointly studying a group of cases in order to inquire into the phenomenon.

Where Do You Find Data for a Case Study?

There are several places to find data for a case study. The key is to gather data from multiple sources to get a complete picture of the case and corroborate facts or findings through triangulation of evidence. Most of this information is likely qualitative (i.e., verbal description rather than measurement), but the psychologist might also collect numerical data.

1. Primary sources

  • Interviews – Interviewing key people related to the case to get their perspectives and insights. The interview is an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates, and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
  • Observations – Observing behaviors, interactions, processes, etc., related to the case as they unfold in real-time.
  • Documents & Records – Reviewing private documents, diaries, public records, correspondence, meeting minutes, etc., relevant to the case.

2. Secondary sources

  • News/Media – News coverage of events related to the case study.
  • Academic articles – Journal articles, dissertations etc. that discuss the case.
  • Government reports – Official data and records related to the case context.
  • Books/films – Books, documentaries or films discussing the case.

3. Archival records

Searching historical archives, museum collections and databases to find relevant documents, visual/audio records related to the case history and context.

Public archives like newspapers, organizational records, photographic collections could all include potentially relevant pieces of information to shed light on attitudes, cultural perspectives, common practices and historical contexts related to psychology.

4. Organizational records

Organizational records offer the advantage of often having large datasets collected over time that can reveal or confirm psychological insights.

Of course, privacy and ethical concerns regarding confidential data must be navigated carefully.

However, with proper protocols, organizational records can provide invaluable context and empirical depth to qualitative case studies exploring the intersection of psychology and organizations.

  • Organizational/industrial psychology research : Organizational records like employee surveys, turnover/retention data, policies, incident reports etc. may provide insight into topics like job satisfaction, workplace culture and dynamics, leadership issues, employee behaviors etc.
  • Clinical psychology : Therapists/hospitals may grant access to anonymized medical records to study aspects like assessments, diagnoses, treatment plans etc. This could shed light on clinical practices.
  • School psychology : Studies could utilize anonymized student records like test scores, grades, disciplinary issues, and counseling referrals to study child development, learning barriers, effectiveness of support programs, and more.

How do I Write a Case Study in Psychology?

Follow specified case study guidelines provided by a journal or your psychology tutor. General components of clinical case studies include: background, symptoms, assessments, diagnosis, treatment, and outcomes. Interpreting the information means the researcher decides what to include or leave out. A good case study should always clarify which information is the factual description and which is an inference or the researcher’s opinion.

1. Introduction

  • Provide background on the case context and why it is of interest, presenting background information like demographics, relevant history, and presenting problem.
  • Compare briefly to similar published cases if applicable. Clearly state the focus/importance of the case.

2. Case Presentation

  • Describe the presenting problem in detail, including symptoms, duration,and impact on daily life.
  • Include client demographics like age and gender, information about social relationships, and mental health history.
  • Describe all physical, emotional, and/or sensory symptoms reported by the client.
  • Use patient quotes to describe the initial complaint verbatim. Follow with full-sentence summaries of relevant history details gathered, including key components that led to a working diagnosis.
  • Summarize clinical exam results, namely orthopedic/neurological tests, imaging, lab tests, etc. Note actual results rather than subjective conclusions. Provide images if clearly reproducible/anonymized.
  • Clearly state the working diagnosis or clinical impression before transitioning to management.

3. Management and Outcome

  • Indicate the total duration of care and number of treatments given over what timeframe. Use specific names/descriptions for any therapies/interventions applied.
  • Present the results of the intervention,including any quantitative or qualitative data collected.
  • For outcomes, utilize visual analog scales for pain, medication usage logs, etc., if possible. Include patient self-reports of improvement/worsening of symptoms. Note the reason for discharge/end of care.

4. Discussion

  • Analyze the case, exploring contributing factors, limitations of the study, and connections to existing research.
  • Analyze the effectiveness of the intervention,considering factors like participant adherence, limitations of the study, and potential alternative explanations for the results.
  • Identify any questions raised in the case analysis and relate insights to established theories and current research if applicable. Avoid definitive claims about physiological explanations.
  • Offer clinical implications, and suggest future research directions.

5. Additional Items

  • Thank specific assistants for writing support only. No patient acknowledgments.
  • References should directly support any key claims or quotes included.
  • Use tables/figures/images only if substantially informative. Include permissions and legends/explanatory notes.
  • Provides detailed (rich qualitative) information.
  • Provides insight for further research.
  • Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach, case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research that only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension of experience, which is important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is, therefore, important for psychologists who adopt a holistic point of view (i.e., humanistic psychologists ).

Limitations

  • Lacking scientific rigor and providing little basis for generalization of results to the wider population.
  • Researchers’ own subjective feelings may influence the case study (researcher bias).
  • Difficult to replicate.
  • Time-consuming and expensive.
  • The volume of data, together with the time restrictions in place, impacted the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group, we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e., descriptive) data , a lot depends on the psychologist’s interpretation of the information she has acquired.

This means that there is a lot of scope for Anna O , and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit particular behavioral theories (e.g., Little Hans ).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory.

The Psychology of (Dis)information: Case Studies and Implications

The absorption and spread of disinformation is a pervasive phenomenon across a wide variety of topics on virtually every social media network. The avalanche of COVID-19 disinformation that has been produced over the last 18 months typifies the prevalence of disinformation in the modern world. In fact, a 2018 MIT study of Twitter data found that disinformation was more successful than truth on social media by almost every known metric; it spread “significantly farther, faster, deeper, and more broadly than the truth in all categories of information.”

Further, the absorption and spread of disinformation is a growing national security concern. Most of our adversaries recognize that controlling the information space, including domestic and international narratives, promotes their national interests. For example, in 2013, the Russian chief of the General Staff, Valeriy Gerasimov, stated that the development of information weapons had the ability to reduce an adversary’s combat potential. Also, in 2013, Chinese president Xi Jinping stated that the use of innovative techniques to spread narratives positive for China, and promoting the Chinese view globally, was a priority.

Although the use of information operations is not a new phenomenon—various actors have used them throughout history for a range of objectives—the connectivity that characterizes the world today allows both information and disinformation to spread faster and with a much greater reach. The use of disinformation has led directly to real-world events and violence. It can have a demonstrable effect on a recipient’s behavior, and can lead its promulgators to achieve some goals simply through its existence, regardless of its believability.

Recognizing that disinformation’s primary effect is on the mind, this report describes four psychological mechanisms that are associated with the absorption and spread of disinformation. It then connects five, recent, real-world examples of disinformation in which absorption and spread benefited from the psychological mechanisms described. Finally, it describes possible ways the Department of Defense (DOD) can mitigate the absorption and spread of disinformation among US servicemembers by focusing on the psychological mechanisms that contribute to its promulgation. 

Psychological mechanisms associated with disinformation spread 

This report describes four key psychological mechanisms and explains how each one contributes to the absorption and spread of disinformation:

  • Initial information processing: Our mental “processing capacity” is limited; we simply cannot deeply attend to all new information we encounter. Our brains take mental shortcuts to incorporating new information, and those shortcuts can open us up to mistakes. To the extent that we do not process information as thoroughly as we should, we can construe disinformation as true information.
  • Cognitive dissonance: Cognitive dissonance describes the discomfort we feel when we are confronted with two competing ideas and wish to reduce that discomfort. If disinformation supports our initial beliefs or creates less dissonance than true information, we are more likely to believe the disinformation.
  • Influence of group membership, beliefs, and novelty (the GBN model): Not all information is equally valuable to individuals. Our group memberships, our beliefs, and the uniqueness of the information influence whether we absorb and share disinformation. We are more likely to share information with people we consider members of our group, when we believe the information is true, and when it is novel or urgent. If disinformation comes from a group member with whom we identify, is consistent with our beliefs, or is new information for us, we are more likely to share it.
  • Role of emotion and arousal in our sharing of disinformation: Just as not all information is equally valuable, not all information affects us the same way. Research demonstrates that we pay more attention to information that makes us feel positively (i.e., good) or that arouses us to act. Given that disinformation is, by definition, created by someone, it is more likely to be absorbed and shared if it is constructed to be emotional and arousing.

A critical takeaway from the identification of these mechanisms is that they are not unique to absorbing and spreading disinformation. These same mechanisms are key to absorbing and spreading true information as well. Thus, at an individual level, it  appears that disinformation is absorbed and spread through normal, routine, and adaptive mechanisms, which malign actors can exploit and manipulate for their own objectives.

Case studies in psychology offer real-life examples that allow researchers and practitioners to apply theoretical concepts to actual scenarios, a practice famously exemplified by Sigmund Freud in his clinical work.

Freud’s use of case studies, such as the famous ‘Anna O.’ case, revolutionized how psychologists understand and treat mental disorders.

These in-depth investigations delve into an individual’s thoughts, emotions, and behaviors, providing rich data for analyzing psychological principles in action.

By examining specific cases, professionals can gain insights into varying mental health conditions, like schizophrenia, PTSD, or phobias.

Allow for In-depth Analysis

Case studies enable researchers to conduct in-depth analyses of complex psychological phenomena, facilitating detailed data collection and rigorous analysis methods.

By delving deeply into individual cases, researchers can gather rich, detailed information that may not be accessible through other research methods.

Data collection techniques such as interviews, observations, and archival research are commonly employed to gather comprehensive data.

Analytical approaches such as thematic analysis, content analysis, and grounded theory are then utilized to interpret the gathered information and derive meaningful insights.

Through this intricate process, researchers can uncover nuanced patterns, behaviors, and underlying psychological dynamics, leading to qualitative research that offers valuable insights into human behavior and cognition.

Help in Generating Hypotheses

Case studies play a key role in generating hypotheses within psychology by providing rich qualitative data that can inform diagnostic processes and research directions.

These in-depth analyses of individual cases allow researchers to delve into specific behaviors, experiences, and psychological phenomena, offering detailed insights that can lead to the formulation of new theories or test existing hypotheses.

  • By examining unique cases, psychologists can identify patterns, outliers, and uncommon manifestations that expand their understanding of mental health conditions and human behavior.
  • The flexibility of case study research methods enables researchers to adapt their approach to each unique case, accommodating the complex and intricate nature of psychological disorders.

This nuanced exploration of individual experiences and symptoms contributes significantly to the development of accurate diagnostic criteria and effective treatment strategies, enhancing the overall quality of psychological research and clinical practice.

Provide Insight into Rare Phenomena

Case studies offer valuable insights into rare psychological phenomena that may not be easily captured through traditional research methods, such as the application of cognitive behavioral therapy in exceptional cases.

These in-depth examinations of individual cases allow researchers to delve deeper into unique psychological abnormalities that may defy standard treatment strategies. For instance, rare cases of dissociative identity disorder have shown remarkable progress with the implementation of cognitive behavioral therapy , shedding light on the potential effectiveness of this unconventional approach. Through detailed narratives of patient experiences and therapeutic interventions, case studies provide a rich source of information for psychologists and therapists alike, offering a nuanced understanding of complex psychological conditions.

Can be Used in Ethically Sensitive Situations

Case studies are instrumental in addressing ethically sensitive situations within psychology, ensuring the competence and adherence to ethical guidelines in clinical practice and research.

In the realm of clinical settings, it is imperative for psychologists to uphold the highest ethical standards when dealing with delicate ethical dilemmas that may arise. By diving into case studies, professionals can gain valuable insights into the complexities of ethical decision-making processes. For a better understanding of the importance of case studies in psychology, you can refer to this external link .

The application of ethical principles plays a fundamental role in safeguarding the welfare of clients and maintaining trust in the therapeutic relationship. Ethical considerations serve as the moral compass guiding psychologists in navigating intricate scenarios that may challenge their professional integrity.

How Are Case Studies Conducted in Psychology?

Case studies in psychology are conducted through a systematic process involving the selection of a case, data collection, thorough analysis, and comprehensive reporting of findings.

Regarding selecting a case for a psychological study, researchers typically look for rich and detailed examples that can provide valuable insights into specific phenomena or conditions. This selection process often involves careful consideration of factors such as uniqueness, relevance to the research question, and the availability of information.

Data collection methods in psychological case studies can vary, ranging from structured interviews and observations to psychological tests and document analysis. These methods aim to gather comprehensive and reliable data that can offer a deep understanding of the case under investigation.

Once the data is collected, researchers employ various analytical approaches, such as thematic analysis, content analysis, or grounded theory, to identify patterns, themes, and relationships within the data. These analytical techniques help in uncovering significant findings and drawing meaningful conclusions.

Selecting a Case

The initial step in conducting a case study in psychology involves selecting an individual case with a compelling personal history that aligns with the research objectives.

It is paramount to consider the individual’s background, experiences, and unique attributes when choosing a case.

  • Assessing the personal history of the case subject can provide valuable insights into potential factors contributing to their current situation.
  • Ensuring that the research objectives are in harmony with the characteristics of the chosen case helps maintain relevance and coherence in the study.
  • Each case has its own complexities, challenges, and dynamics that can offer rich material for analysis and interpretation.

Therefore, a thorough evaluation of the personal history, alignment with research goals, and distinct qualities of the case individual are crucial steps in the selection process for a psychological case study.

Collecting Data

Data collection in psychological case studies involves various methods such as observational studies , archival record reviews, and direct interviews to gather comprehensive information about the case.

Observational studies, one of the primary data collection techniques in psychological case studies, involve the systematic observation of individuals in their natural environment to understand their behavior and interactions. Researchers closely analyze and document these observations to gain insights into the case under study.

Archival record reviews play a crucial role in accessing historical information related to the case. Researchers sift through records such as medical reports, school transcripts, or legal documents to gather valuable data that provides context and background for the case.

Interview methods offer researchers the opportunity to delve deeper into the case by directly interacting with the individuals involved. Through structured or semi-structured interviews, researchers can gather detailed accounts, emotions, and perspectives, enriching the understanding of the case.

Analyzing Data

Data analysis in psychological case studies involves rigorous examination methods such as interpretative phenomenological analysis to derive meaningful insights from collected information.

This approach aims to uncover underlying themes and patterns within the data, allowing researchers to delve deep into the subjective experiences of individuals studied. Through thematic coding practices, researchers categorize and organize data based on recurring themes or concepts, facilitating a systematic analysis process. By employing analytical rigor and attention to detail, researchers can extract valuable insights that contribute to a more profound understanding of the psychological phenomena under investigation.

Reporting Findings

Reporting findings in psychological case studies follows established guidelines such as the APA format, ensuring clear and concise documentation of the research outcomes and clinical observations.

Following the APA format standards is crucial in the field of psychology as it provides a structured framework for presenting research data and insights. By adhering to these guidelines, researchers can enhance the credibility and reproducibility of their findings, fostering transparency in the scientific community.

The meticulous reporting of results not only aids in the replication of studies but also facilitates the integration of new knowledge into existing theories and practices. Maintaining consistency in clinical documentation allows for effective communication among professionals, promoting collaborative efforts in advancing psychological research.

What Are the Different Types of Case Studies in Psychology?

In psychology, various types of case studies exist, including descriptive case studies that aim to provide detailed accounts and explanatory case studies that focus on understanding underlying psychological mechanisms.

Descriptive case studies often involve extensive qualitative data collection through methods such as interviews, observations, and document analysis to present a rich narrative of an individual’s experiences or behaviors.

On the other hand, explanatory case studies delve deeper into the causal relationships between variables, seeking to uncover the reasons behind certain psychological phenomena or behaviors.

While descriptive studies offer a comprehensive portrayal, explanatory studies strive to unravel the ‘why’ and ‘how’ aspects, shedding light on the mechanisms at play in complex psychological processes.

Descriptive Case Studies

Descriptive case studies in psychology involve detailed observations and analyses of individual cases to provide comprehensive insights into behavior and psychological processes.

Observational research methods play a crucial role in conducting descriptive case studies, allowing researchers to directly observe and document the behaviors and responses of the individuals under study. These methods often involve naturalistic observations in real-life settings, providing rich and nuanced data for analysis. Researchers often employ thematic coding practices to categorize and analyze the qualitative data collected during these observations, identifying recurring themes and patterns within the behavior of the case subjects.

Exploratory Case Studies

Exploratory case studies in psychology aim to delve into new areas of research, employing thematic coding to identify patterns and themes within the collected data.

Thematic coding, a crucial methodology in these studies, involves categorizing data based on recurring themes and concepts that emerge during analysis. This process allows researchers to uncover hidden connections and gain deeper insight into the phenomena under investigation.

Longitudinal studies, often utilized in exploratory research, provide a temporal perspective by tracking changes and developments over an extended period. This longitudinal approach enables researchers to observe how patterns evolve over time, offering a more comprehensive understanding of complex psychological processes.

Explanatory Case Studies

Explanatory case studies in psychology focus on understanding the underlying psychological phenomena through interpretative phenomenological analysis, uncovering the complexities of individual behavior.

By utilizing interpretative phenomenological analysis methods, researchers can delve deep into the subjective experiences and perceptions of participants, providing rich insights into the intricate workings of the human mind. These case studies serve as valuable tools for theory testing approaches, allowing psychologists to explore the applicability and validity of existing theories in real-world contexts.

The theoretical interpretations derived from these studies help in advancing our understanding of psychological processes, shedding light on factors that influence behavior, emotions, and cognition. Through detailed qualitative analysis, researchers can capture the nuances and subtleties of individual differences and diverse psychological phenomena, contributing to the broader field of psychology.

Collective Case Studies

Collective case studies in psychology involve the examination of multiple cases or a group of individuals over an extended period, often utilizing longitudinal study designs to capture developmental changes.

The primary goal of collective case studies is to provide a comprehensive understanding of specific phenomena by observing patterns across different cases. By analyzing these cases simultaneously, researchers can gain insights into shared experiences, unique outcomes, and variations that might occur within the group.

Longitudinal study frameworks in collective case studies allow researchers to track changes over time, providing valuable data on long-term behavioral patterns and psychological development.

Cross-sectional comparisons, on the other hand, enable researchers to compare different cases at a specific point in time, helping identify similarities, differences, and potential factors influencing group dynamics.

Single-Case Studies

Single-case studies in psychology focus on individual cases, allowing for a detailed examination of unique behaviors and psychological patterns while addressing potential researcher biases.

By diving into a single individual’s experience, researchers can gain in-depth insights into specific behaviors and responses. This approach enables a focused analysis of the complexities that may not be observable in larger samples, leading to a nuanced understanding of psychological phenomena.

Scientific rigor plays a crucial role in single-case studies, requiring meticulous observation, documentation, and interpretation to uphold the validity and reliability of findings.

Attention to ethical considerations is paramount in these studies, ensuring the well-being and autonomy of the participant while maintaining the integrity of the research process. Researchers must also navigate the limitations inherent in single-case studies, such as generalizability issues and the need for robust experimental controls to establish causal relationships.

Multiple-Case Studies

Multiple-case studies in psychology involve the comparison of several cases to identify commonalities, differences, and patterns, allowing for generalizations within specific contexts.

When conducting multiple-case studies, researchers typically aim to extend beyond individual case analyses to explore overarching themes and patterns that may apply to a larger population or phenomenon.

By utilizing comparative analysis, researchers can delve into the nuances of each case, observing the interplay of various factors and variables that contribute to specific outcomes.

Through this method, researchers can test existing theories, refine hypotheses, and develop new insights that contribute to the broader understanding of complex psychological phenomena.

What Is a Case Study in Psychology?

Sharing is caring!

A case study is a research method used in psychology to investigate a particular individual, group, or situation in depth . It involves a detailed analysis of the subject, gathering information from various sources such as interviews, observations, and documents.

In a case study, researchers aim to understand the complexities and nuances of the subject under investigation. They explore the individual’s thoughts, feelings, behaviors, and experiences to gain insights into specific psychological phenomena. 

This type of research can provide great detail regarding a particular case, allowing researchers to examine rare or unique situations that may not be easily replicated in a laboratory setting. They offer a holistic view of the subject, considering various factors influencing their behavior or mental processes. 

By examining individual cases, researchers can generate hypotheses, develop theories, and contribute to the existing body of knowledge in psychology. Case studies are often utilized in clinical psychology, where they can provide valuable insights into the diagnosis, treatment, and outcomes of specific psychological disorders. 

Case studies offer a comprehensive and in-depth understanding of complex psychological phenomena, providing researchers with valuable information to inform theory, practice, and future research.

Examples of Case Studies in Psychology

Case studies in psychology provide real-life examples that illustrate psychological concepts and theories. They offer a detailed analysis of specific individuals, groups, or situations, allowing researchers to understand psychological phenomena better. Here are a few examples of case studies in psychology: 

Phineas Gage

This famous case study explores the effects of a traumatic brain injury on personality and behavior. A railroad construction worker, Phineas Gage survived a severe brain injury that dramatically changed his personality.

This case study helped researchers understand the role of the frontal lobe in personality and social behavior. 

Little Albert

Conducted by behaviorist John B. Watson, the Little Albert case study aimed to demonstrate classical conditioning. In this study, a young boy named Albert was conditioned to fear a white rat by pairing it with a loud noise.

This case study provided insights into the process of fear conditioning and the impact of early experiences on behavior. 

Genie’s case study focused on a girl who experienced extreme social isolation and deprivation during her childhood. This study shed light on the critical period for language development and the effects of severe neglect on cognitive and social functioning. 

These case studies highlight the value of in-depth analysis and provide researchers with valuable insights into various psychological phenomena. By examining specific cases, psychologists can uncover unique aspects of human behavior and contribute to the field’s knowledge and understanding.

Types of Case Studies in Psychology

Psychology case studies come in various forms, each serving a specific purpose in research and analysis. Understanding the different types of case studies can help researchers choose the most appropriate approach. 

Descriptive Case Studies

These studies aim to describe a particular individual, group, or situation. Researchers use descriptive case studies to explore and document specific characteristics, behaviors, or experiences.

For example, a descriptive case study may examine the life and experiences of a person with a rare psychological disorder. 

Exploratory Case Studies

Exploratory case studies are conducted when there is limited existing knowledge or understanding of a particular phenomenon. Researchers use these studies to gather preliminary information and generate hypotheses for further investigation.

Exploratory case studies often involve in-depth interviews, observations, and analysis of existing data. 

Explanatory Case Studies

These studies aim to explain the causal relationship between variables or events. Researchers use these studies to understand why certain outcomes occur and to identify the underlying mechanisms or processes.

Explanatory case studies often involve comparing multiple cases to identify common patterns or factors. 

Instrumental Case Studies

Instrumental case studies focus on using a particular case to gain insights into a broader issue or theory. Researchers select cases that are representative or critical in understanding the phenomenon of interest.

Instrumental case studies help researchers develop or refine theories and contribute to the general knowledge in the field. 

By utilizing different types of case studies, psychologists can explore various aspects of human behavior and gain a deeper understanding of psychological phenomena. Each type of case study offers unique advantages and contributes to the overall body of knowledge in psychology.

How to Collect Data for a Case Study

There are a variety of ways that researchers gather the data they need for a case study. Some sources include:

  • Directly observing the subject
  • Collecting information from archival records
  • Conducting interviews
  • Examining artifacts related to the subject
  • Examining documents that provide information about the subject

The way that this information is collected depends on the nature of the study itself

Prospective Research

In a prospective study, researchers observe the individual or group in question. These observations typically occur over a period of time and may be used to track the progress or progression of a phenomenon or treatment.

Retrospective Research

A retrospective case study involves looking back on a phenomenon. Researchers typically look at the outcome and then gather data to help them understand how the individual or group reached that point.

Benefits of a Case Study

Case studies offer several benefits in the field of psychology. They provide researchers with a unique opportunity to delve deep into specific individuals, groups, or situations, allowing for a comprehensive understanding of complex phenomena.

Case studies offer valuable insights that can inform theory development and practical applications by examining real-life examples. 

Complex Data

One of the key benefits of case studies is their ability to provide complex and detailed data. Researchers can gather in-depth information through various methods such as interviews, observations, and analysis of existing records.

This depth of data allows for a thorough exploration of the factors influencing behavior and the underlying mechanisms at play. 

Unique Data

Additionally, case studies allow researchers to study rare or unique cases that may not be easily replicated in experimental settings. This enables the examination of phenomena that are difficult to study through other psychology research methods . 

By focusing on specific cases, researchers can uncover patterns, identify causal relationships, and generate hypotheses for further investigation.

General Knowledge

Case studies can also contribute to the general knowledge of psychology by providing real-world examples that can be used to support or challenge existing theories. They offer a bridge between theory and practice, allowing researchers to apply theoretical concepts to real-life situations and vice versa. 

Case studies offer a range of benefits in psychology, including providing rich and detailed data, studying unique cases, and contributing to theory development. These benefits make case studies valuable in understanding human behavior and psychological phenomena.

Limitations of a Case Study

While case studies offer numerous benefits in the field of psychology, they also have certain limitations that researchers need to consider. Understanding these limitations is crucial for interpreting the findings and generalizing the results. 

Lack of Generalizability

One limitation of case studies is the issue of generalizability. Since case studies focus on specific individuals, groups, and situations, applying the findings to a larger population can be challenging. The unique characteristics and circumstances of the case may not be representative of the broader population, making it difficult to draw universal conclusions. 

Researcher bias is another possible limitation. The researcher’s subjective interpretation and personal beliefs can influence the data collection, analysis, and interpretation process. This bias can affect the objectivity and reliability of the findings, raising questions about the study’s validity. 

Case studies are often time-consuming and resource-intensive. They require extensive data collection, analysis, and interpretation, which can be lengthy. This can limit the number of cases that can be studied and may result in a smaller sample size, reducing the study’s statistical power. 

Case studies are retrospective in nature, relying on past events and experiences. This reliance on memory and self-reporting can introduce recall bias and inaccuracies in the data. Participants may forget or misinterpret certain details, leading to incomplete or unreliable information.

Despite these limitations, case studies remain a valuable research tool in psychology. By acknowledging and addressing these limitations, researchers can enhance the validity and reliability of their findings, contributing to a more comprehensive understanding of human behavior and psychological phenomena. 

While case studies have limitations, they remain valuable when researchers acknowledge and address these concerns, leading to more reliable and valid findings in psychology.

Psychology embraces a diverse range of methodologies. However, most rely on averaging group data to draw conclusions. In this Perspective, we argue that single case methodology is a valuable tool for developing and extending psychological theories. We stress the importance of single case and case series research, drawing on classic and contemporary cases in which cognitive and perceptual deficits provide insights into typical cognitive processes in domains such as memory, delusions, reading and face perception. We unpack the key features of single case methodology, describe its strengths, its value in adjudicating between theories, and outline its benefits for a better understanding of deficits and hence more appropriate interventions. The unique insights that single case studies have provided illustrate the value of in-depth investigation within an individual. Single case methodology has an important place in the psychologist’s toolkit and it should be valued as a primary research tool.

What Is A Case Study In Psychology?

When people think about psychology studies, they are most likely to think about studies involving several participants split across a number of experimental and control groups. Studies like this are a good way to investigate the effect of a certain treatment or activity, but they are not always the best option. For example, if a scientist is interested in a specific rare disease, they cannot always find enough people with that disease to participate in a useful study. Similarly, one cannot give a group of participants a rare disease (for obvious reasons) and compare them to a group of participants without that disease. For situations like this, there are case studies.

What is a case study?

A case study is, as the name suggests, a study of a single case. For example, if someone has an extremely rare disease, a group of scientists might conduct a case study of that disease rather than attempting to set up an experimental study. In that case study, the researchers might test the effectiveness of a certain drug in treating that disease and carefully document the response of that participant over time.

Of course, the results seen in that one participant will not necessarily apply to all people with that rare disease. However, if the case study shows promising results, that treatment can then be tested in a larger experimental study. If it does not, it indicates that the treatment is not necessarily effective, at least in people that are similar to the original participant in the case study.

Why are case studies useful in psychology?

When people are still learning about psychology, they might think that group studies showing group effects are always better than individual studies showing individual effects. Of course, there is some truth to this notion, as results obtained from a large number of people are likely to be more generalizable than results obtained from a single person. However, this does not mean that we should discount the importance of individual effects.

Consider the following: In studies looking solely at group effects, individual effects can be masked. In other words, certain statistical quirks can lead to the appearance of a group effect despite the fact that no single individual showed that effect. While this is rare, it is possible. For this reason, it is important to consider individual effects. That is why, even in experimental studies examining groups, it can be useful to examine individual effects within that group. This underlines the value of case studies.

Wrapping up

At the end of the day, there are many good reasons that experimental studies examining groups are the most common types of psychological studies. However, case studies are also extremely valuable, particularly when group experiments are less feasible. Just as psychology is a large topic encompassing a wide variety of factors, both case studies and experimental group studies should be used in the larger overall strategy of psychology research.

Psychology Case Study Examples: A Deep Dive into Real-life Scenarios

Psychology Case Study Examples

Peeling back the layers of the human mind is no easy task, but psychology case studies can help us do just that. Through these detailed analyses, we’re able to gain a deeper understanding of human behavior, emotions, and cognitive processes. I’ve always found it fascinating how a single person’s experience can shed light on broader psychological principles.

Over the years, psychologists have conducted numerous case studies—each with their own unique insights and implications. These investigations range from Phineas Gage’s accidental lobotomy to Genie Wiley’s tragic tale of isolation. Such examples not only enlighten us about specific disorders or occurrences but also continue to shape our overall understanding of psychology .

As we delve into some noteworthy examples , I assure you’ll appreciate how varied and intricate the field of psychology truly is. Whether you’re a budding psychologist or simply an eager learner, brace yourself for an intriguing exploration into the intricacies of the human psyche.

Understanding Psychology Case Studies

Diving headfirst into the world of psychology, it’s easy to come upon a valuable tool used by psychologists and researchers alike – case studies. I’m here to shed some light on these fascinating tools.

Psychology case studies, for those unfamiliar with them, are in-depth investigations carried out to gain a profound understanding of the subject – whether it’s an individual, group or phenomenon. They’re powerful because they provide detailed insights that other research methods might miss.

Let me share a few examples to clarify this concept further:

  • One notable example is Freud’s study on Little Hans. This case study explored a 5-year-old boy’s fear of horses and related it back to Freud’s theories about psychosexual stages.
  • Another classic example is Genie Wiley (a pseudonym), a feral child who was subjected to severe social isolation during her early years. Her heartbreaking story provided invaluable insights into language acquisition and critical periods in development.

You see, what sets psychology case studies apart is their focus on the ‘why’ and ‘how’. While surveys or experiments might tell us ‘what’, they often don’t dig deep enough into the inner workings behind human behavior.

It’s important though not to take these psychology case studies at face value. As enlightening as they can be, we must remember that they usually focus on one specific instance or individual. Thus, generalizing findings from single-case studies should be done cautiously.

To illustrate my point using numbers: let’s say we have 1 million people suffering from condition X worldwide; if only 20 unique cases have been studied so far (which would be quite typical for rare conditions), then our understanding is based on just 0.002% of the total cases! That’s why multiple sources and types of research are vital when trying to understand complex psychological phenomena fully.

In the grand scheme of things, psychology case studies are just one piece of the puzzle – albeit an essential one. They provide rich, detailed data that can form the foundation for further research and understanding. As we delve deeper into this fascinating field, it’s crucial to appreciate all the tools at our disposal – from surveys and experiments to these insightful case studies.

Importance of Case Studies in Psychology

I’ve always been fascinated by the human mind, and if you’re here, I bet you are too. Let’s dive right into why case studies play such a pivotal role in psychology.

One of the key reasons they matter so much is because they provide detailed insights into specific psychological phenomena. Unlike other research methods that might use large samples but only offer surface-level findings, case studies allow us to study complex behaviors, disorders, and even treatments at an intimate level. They often serve as a catalyst for new theories or help refine existing ones.

To illustrate this point, let’s look at one of psychology’s most famous case studies – Phineas Gage. He was a railroad construction foreman who survived a severe brain injury when an iron rod shot through his skull during an explosion in 1848. The dramatic personality changes he experienced after his accident led to significant advancements in our understanding of the brain’s role in personality and behavior.

Moreover, it’s worth noting that some rare conditions can only be studied through individual cases due to their uncommon nature. For instance, consider Genie Wiley – a girl discovered at age 13 having spent most of her life locked away from society by her parents. Her tragic story gave psychologists valuable insights into language acquisition and critical periods for learning.

Finally yet importantly, case studies also have practical applications for clinicians and therapists. Studying real-life examples can inform treatment plans and provide guidance on how theoretical concepts might apply to actual client situations.

  • Detailed insights: Case studies offer comprehensive views on specific psychological phenomena.
  • Catalyst for new theories: Real-life scenarios help shape our understanding of psychology .
  • Study rare conditions: Unique cases can offer invaluable lessons about uncommon disorders.
  • Practical applications: Clinicians benefit from studying real-world examples.

In short (but without wrapping up), it’s clear that case studies hold immense value within psychology – they illuminate what textbooks often can’t, offering a more nuanced understanding of human behavior.

Different Types of Psychology Case Studies

Diving headfirst into the world of psychology, I can’t help but be fascinated by the myriad types of case studies that revolve around this subject. Let’s take a closer look at some of them.

Firstly, we’ve got what’s known as ‘Explanatory Case Studies’. These are often used when a researcher wants to clarify complex phenomena or concepts. For example, a psychologist might use an explanatory case study to explore the reasons behind aggressive behavior in children.

Second on our list are ‘Exploratory Case Studies’, typically utilized when new and unexplored areas of research come up. They’re like pioneers; they pave the way for future studies. In psychological terms, exploratory case studies could be conducted to investigate emerging mental health conditions or under-researched therapeutic approaches.

Next up are ‘Descriptive Case Studies’. As the name suggests, these focus on depicting comprehensive and detailed profiles about a particular individual, group, or event within its natural context. A well-known example would be Sigmund Freud’s analysis of “Anna O”, which provided unique insights into hysteria.

Then there are ‘Intrinsic Case Studies’, which delve deep into one specific case because it is intrinsically interesting or unique in some way. It’s sorta like shining a spotlight onto an exceptional phenomenon. An instance would be studying savants—individuals with extraordinary abilities despite significant mental disabilities.

Lastly, we have ‘Instrumental Case Studies’. These aren’t focused on understanding a particular case per se but use it as an instrument to understand something else altogether—a bit like using one puzzle piece to make sense of the whole picture!

So there you have it! From explanatory to instrumental, each type serves its own unique purpose and adds another intriguing layer to our understanding of human behavior and cognition.

Exploring Real-Life Psychology Case Study Examples

Let’s roll up our sleeves and delve into some real-life psychology case study examples. By digging deep, we can glean valuable insights from these studies that have significantly contributed to our understanding of human behavior and mental processes.

First off, let me share the fascinating case of Phineas Gage. This gentleman was a 19th-century railroad construction foreman who survived an accident where a large iron rod was accidentally driven through his skull, damaging his frontal lobes. Astonishingly, he could walk and talk immediately after the accident but underwent dramatic personality changes, becoming impulsive and irresponsible. This case is often referenced in discussions about brain injury and personality change.

Next on my list is Genie Wiley’s heart-wrenching story. She was a victim of severe abuse and neglect resulting in her being socially isolated until she was 13 years old. Due to this horrific experience, Genie couldn’t acquire language skills typically as other children would do during their developmental stages. Her tragic story offers invaluable insight into the critical periods for language development in children.

Then there’s ‘Little Hans’, a classic Freudian case that delves into child psychology. At just five years old, Little Hans developed an irrational fear of horses -or so it seemed- which Sigmund Freud interpreted as symbolic anxiety stemming from suppressed sexual desires towards his mother—quite an interpretation! The study gave us Freud’s Oedipus Complex theory.

Lastly, I’d like to mention Patient H.M., an individual who became amnesiac following surgery to control seizures by removing parts of his hippocampus bilaterally. His inability to form new memories post-operation shed light on how different areas of our brains contribute to memory formation.

Each one of these real-life psychology case studies gives us a unique window into understanding complex human behaviors better – whether it’s dissecting the role our brain plays in shaping personality or unraveling the mysteries of fear, language acquisition, and memory.

How to Analyze a Psychology Case Study

Diving headfirst into a psychology case study, I understand it can seem like an intimidating task. But don’t worry, I’m here to guide you through the process.

First off, it’s essential to go through the case study thoroughly. Read it multiple times if needed. Each reading will likely reveal new information or perspectives you may have missed initially. Look out for any patterns or inconsistencies in the subject’s behavior and make note of them.

Next on your agenda should be understanding the theoretical frameworks that might be applicable in this scenario. Is there a cognitive-behavioral approach at play? Or does psychoanalysis provide better insights? Comparing these theories with observed behavior and symptoms can help shed light on underlying psychological issues.

Now, let’s talk data interpretation. If your case study includes raw data like surveys or diagnostic tests results, you’ll need to analyze them carefully. Here are some steps that could help:

  • Identify what each piece of data represents
  • Look for correlations between different pieces of data
  • Compute statistics (mean, median, mode) if necessary
  • Use graphs or charts for visual representation

Keep in mind; interpreting raw data requires both statistical knowledge and intuition about human behavior.

Finally, drafting conclusions is key in analyzing a psychology case study. Based on your observations, evaluations of theoretical approaches and interpretations of any given data – what do you conclude about the subject’s mental health status? Remember not to jump to conclusions hastily but instead base them solidly on evidence from your analysis.

In all this journey of analysis remember one thing: every person is unique and so are their experiences! So while theories and previous studies guide us, they never define an individual completely.

Applying Lessons from Psychology Case Studies

Let’s dive into how we can apply the lessons learned from psychology case studies. If you’ve ever studied psychology, you’ll know that case studies offer rich insights. They shed light on human behavior, mental health issues, and therapeutic techniques. But it’s not just about understanding theory. It’s also about implementing these valuable lessons in real-world situations.

One of the most famous psychological case studies is Phineas Gage’s story. This 19th-century railroad worker survived a severe brain injury which dramatically altered his personality. From this study, we gained crucial insight into how different brain areas are responsible for various aspects of our personality and behavior.

  • Lesson: Recognizing that damage to specific brain areas can result in personality changes, enabling us to better understand certain mental conditions.

Sigmund Freud’s work with a patient known as ‘Anna O.’ is another landmark psychology case study. Anna displayed what was then called hysteria – symptoms included hallucinations and disturbances in speech and physical coordination – which Freud linked back to repressed memories of traumatic events.

  • Lesson: The importance of exploring an individual’s history for understanding their current psychological problems – a principle at the heart of psychoanalysis.

Then there’s Genie Wiley’s case – a girl who suffered extreme neglect resulting in impaired social and linguistic development. Researchers used her tragic circumstances as an opportunity to explore theories around language acquisition and socialization.

  • Lesson: Reinforcing the critical role early childhood experiences play in shaping cognitive development.

Lastly, let’s consider the Stanford Prison Experiment led by Philip Zimbardo examining how people conform to societal roles even when they lead to immoral actions.

  • Lesson: Highlighting that situational forces can drastically impact human behavior beyond personal characteristics or morality.

These examples demonstrate that psychology case studies aren’t just academic exercises isolated from daily life. Instead, they provide profound lessons that help us make sense of complex human behaviors, mental health issues, and therapeutic strategies. By understanding these studies, we’re better equipped to apply their lessons in our own lives – whether it’s navigating personal relationships, working with diverse teams at work or even self-improvement.

Challenges and Critiques of Psychological Case Studies

Delving into the world of psychological case studies, it’s not all rosy. Sure, they offer an in-depth understanding of individual behavior and mental processes. Yet, they’re not without their share of challenges and criticisms.

One common critique is the lack of generalizability. Each case study is unique to its subject. We can’t always apply what we learn from one person to everyone else. I’ve come across instances where results varied dramatically between similar subjects, highlighting the inherent unpredictability in human behavior.

Another challenge lies within ethical boundaries. Often, sensitive information surfaces during these studies that could potentially harm the subject if disclosed improperly. To put it plainly, maintaining confidentiality while delivering a comprehensive account isn’t always easy.

Distortion due to subjective interpretations also poses substantial difficulties for psychologists conducting case studies. The researcher’s own bias may color their observations and conclusions – leading to skewed outcomes or misleading findings.

Moreover, there’s an ongoing debate about the scientific validity of case studies because they rely heavily on qualitative data rather than quantitative analysis. Some argue this makes them less reliable or objective when compared with other research methods such as experiments or surveys.

To summarize:

  • Lack of generalizability
  • Ethical dilemmas concerning privacy
  • Potential distortion through subjective interpretation
  • Questions about scientific validity

While these critiques present significant challenges, they do not diminish the value that psychological case studies bring to our understanding of human behavior and mental health struggles.

Conclusion: The Impact of Case Studies in Understanding Human Behavior

Case studies play a pivotal role in shedding light on human behavior. Throughout this article, I’ve discussed numerous examples that illustrate just how powerful these studies can be. Yet it’s the impact they have on our understanding of human psychology where their true value lies.

Take for instance the iconic study of Phineas Gage. It was through his tragic accident and subsequent personality change that we began to grasp the profound influence our frontal lobes have on our behavior. Without such a case study, we might still be in the dark about this crucial aspect of our neurology.

Let’s also consider Genie, the feral child who showed us the critical importance of social interaction during early development. Her heartbreaking story underscores just how vital appropriate nurturing is for healthy mental and emotional growth.

Here are some key takeaways from these case studies:

  • Our brain structure significantly influences our behavior.
  • Social interaction during formative years is vital for normal psychological development.
  • Studying individual cases can reveal universal truths about human nature.

What stands out though, is not merely what these case studies teach us individually but collectively. They remind us that each person constitutes a unique combination of various factors—biological, psychological, and environmental—that shape their behavior.

One cannot overstate the significance of case studies in psychology—they are more than mere stories or isolated incidents; they’re windows into the complexities and nuances of human nature itself.

In wrapping up, I’d say that while statistics give us patterns and trends to understand groups, it’s these detailed narratives offered by case studies that help us comprehend individuals’ unique experiences within those groups—making them an invaluable part of psychological research.

Psychology Case Study Examples

Experiments are often used to help researchers understand how the human mind works. There have been many famous examples in psychology over the years. Some have shown how phenomena like memory and personality work. Others have been disproven over time. Understanding the study design, data, content, and analytical approach of case studies is important to verifying the validity of each study.

In considering case studies, researchers continuously test and reevaluate the conclusions made by past psychologists to continue offering the most up-to-date and effective care to modern clients. Prospective case studies are continually being developed based on previous findings and multiple case studies done in one area can lend credence to the findings. Learning about the famous psychology case studies can help you understand how research continues to shape what psychologists know about the human experience and mind. 

Examples of the most famous case study in psychology

Hundreds of thousands of case studies have been done in psychology, and narrowing a list of the most ground-breaking studies can be challenging. However, the following seven case studies present findings that have defied expectations, achieved positive outcomes for humanity, and launched further research into existing knowledge gaps within the niche.

Phineas Gage

The case of Phineas Gage is perhaps the  most cited study  in psychology. This famous case study showed how different areas of the brain affect personality and cognitive ability. While working as a construction foreman on a railroad, Phineas Gage was involved in an accident in which a rod was pushed through his cheek and brain. He survived, but because of the accident, both his personality and his ability to learn new skills were affected.

Although the case is frequently cited and referenced in psychology, relatively little information about Gage's life before and after the accident is known. Researchers have discovered that the last two decades of his life were spent in his original job, which may have been unlikely to have been possible if the extent of his injuries were as severe as initially believed. Still, his case was a starting point for psychology research on how memory and personality work in the brain, and it is a seminal study for that reason.

Genie the "feral child"

Although an outdated term, "feral children" referred to children raised without human interaction, often due to abuse or neglect. One  famous case study of a neglected child was done with a child known as Genie. She was raised in a single bedroom with little human interaction. She never gained the cognitive ability of an average adult, even though she was found at age 13. Later in life, she regressed and stopped speaking altogether. Her case has been studied extensively by psychologists who want to understand how enculturation affects cognitive development. It's one of many cognitive psychology examples that have had an impact on this field.

Henry Molaison

The case study  of Henry Molaison has helped psychologists understand memory. It is one of the most famous case studies in neuroscience. Henry Molaison was in a childhood accident that left him with debilitating seizures. Doctors could stop the seizures by removing slivers of his brain's hippocampus, though they did not fully understand what they were doing at the time. As a result, scientists learned how important the hippocampus is to forming long-term memories. After the surgery, Molaison could no longer form long-term memories, and his short-term memory was brief. The case study started further research into memory and the brain.

Jill Price had one of a few documented cases of hyperthymesia, a term for an overactive memory that allowed her to remember such mundane things as what she had for dinner on an average day in August 20th years previously. Her  case study  was used as a jumping-off point to research how memory works and why some people have exceptional memories. 

However, through more research, it was discovered that her overall memory was not exceptional. Rather, she only remembered details of her own life. She was diagnosed with obsessive-compulsive disorder (OCD), with memories being part of her obsession. This case study is still relevant because it has helped modern psychologists understand how mental illness affects memory.

In the John/Joan  case study , a reputable sexologist tested his theory that nurture, not nature, determined gender. The case study has been cited extensively and laid the groundwork for other research into gender identity. However, the case study was not legitimate. In this study, Dr. John Money performed surgery on an infant whose genitals were damaged during circumcision. 

The boy was raised as a girl; however, he never identified as female and eventually underwent gender-affirming surgery as an adult. Because Dr. Money didn't follow up with the patient appropriately and did not report adverse findings, the case study is still often cited as successful.

Anna O. was the pseudonym given to a German woman who was one of the first to undergo psychoanalysis. Her case inspired many of the theories of Freud and other prominent psychologists of the time. It was determined at the time that Anna's symptoms of depression were eliminated through talk therapy. More recently, it has been suggested that Anna O. had another illness, such as epilepsy, from which she may have recovered during the therapy. This  case study is still cited as a reason psychologists believe that psychotherapy, or talk therapy, can be helpful to many patients. 

Victor the "wild boy" of Aveyron

Another study done on a child that had grown up without parents was done with a boy named "Victor" who had been found wandering in the wilderness and was thought to have been living alone for years. The boy could not speak, use the bathroom, or connect with others. However, through the study of his condition, he was able to learn bathroom habits, how to dress, writing, and primary language. Psychologists today speculate that he may have been autistic. 

Ethical concerns for doing a case study

When case studies are flawed through not having enough information or having the wrong information, they can be harmful. Valuable research hours and other resources can be wasted while theories are used for inappropriate treatment. Case studies can therefore cause as much harm as benefit, and psychologists are often careful about how and when they are used.

Those who are not psychologists and are interacting with studies can also practice caution. Psychologists and doctors often disagree on how case studies should be applied. In addition, people without education in psychology may struggle to know whether a case study is built on a faulty premise or misinformation. It can also be possible to generalize case studies to situations they do not apply. If you think a case study might apply to your case or that of a loved one, consider asking a therapist for guidance. 

Case studies are descriptions of real people. The individuals in the studies are studied intensively and often written about in medical journals and textbooks. While some clients may be comfortable being studied for science, others may not have consented due to the inability or lack of consent laws at the time. In addition, some subjects may not have been treated with dignity and respect. 

When considering case study content and findings from psychology, it can be helpful to think of the cases as stories of real individuals. When you strip away the science and look at the case as a whole person in a unique situation, you may get more out of the study than if you look at it as research that proves a theory. 

Therapeutic implications of a case study

Case examples are sometimes used in therapy to determine the best course of treatment. If a typical case study from psychology aligns with your situation, your therapist may use the treatment methods outlined in the study. Psychiatrists and other mental health professionals also use case examples to understand mental illness and its treatment.

Researchers have reviewed the role of case studies in counseling and psychotherapy. In  one study , the authors discussed how reading case studies benefits therapists, providing a conceptual guide for clinical work and an understanding of the theory behind the practice. They also stressed the importance of teaching psychotherapy trainees to do better case study research. They encouraged practitioners to publish more case studies documenting the methods they use in their practice.

How a case study is used in counseling

If you want to meet with a psychologist, counseling may benefit you. Therapists often use theories behind popular case studies and can discuss their implications with you. In addition, you may be able to participate in case studies in your area, as psychologists and psychiatrists often perform clinical trials to understand treatments on a deeper level.

Online therapy can also be beneficial if you cannot find a therapist in your area. Through a platform like BetterHelp , you can get matched with a provider meeting your needs and choose between phone, video, or live chat sessions. When experiencing symptoms of a mental health condition, it can sometimes be hard to leave home for therapy. You can use many online therapy platforms from the comfort and safe space of your own home. 

Therapy is a personal experience; not everyone will go into it seeking the same outcomes. Keeping this in mind may ensure you get the most out of online therapy, regardless of your specific goals. If you're interested in learning more about the effectiveness of online therapy, you can look into various clinical studies that have shown it can be as effective , if not more effective, than in-person options.

A case study research paper examines a person, place, event, condition, phenomenon, or other type of subject of analysis in order to extrapolate  key themes and results that help predict future trends, illuminate previously hidden issues that can be applied to practice, and/or provide a means for understanding an important research problem with greater clarity. A case study research paper usually examines a single subject of analysis, but case study papers can also be designed as a comparative investigation that shows relationships between two or more subjects. The methods used to study a case can rest within a quantitative, qualitative, or mixed-method investigative paradigm.

How to Approach Writing a Case Study Research Paper

General information about how to choose a topic to investigate can be found under the " Choosing a Research Problem " tab in the Organizing Your Social Sciences Research Paper writing guide. Review this page because it may help you identify a subject of analysis that can be investigated using a case study design.

However, identifying a case to investigate involves more than choosing the research problem . A case study encompasses a problem contextualized around the application of in-depth analysis, interpretation, and discussion, often resulting in specific recommendations for action or for improving existing conditions. As Seawright and Gerring note, practical considerations such as time and access to information can influence case selection, but these issues should not be the sole factors used in describing the methodological justification for identifying a particular case to study. Given this, selecting a case includes considering the following:

  • The case represents an unusual or atypical example of a research problem that requires more in-depth analysis? Cases often represent a topic that rests on the fringes of prior investigations because the case may provide new ways of understanding the research problem. For example, if the research problem is to identify strategies to improve policies that support girl's access to secondary education in predominantly Muslim nations, you could consider using Azerbaijan as a case study rather than selecting a more obvious nation in the Middle East. Doing so may reveal important new insights into recommending how governments in other predominantly Muslim nations can formulate policies that support improved access to education for girls.
  • The case provides important insight or illuminate a previously hidden problem? In-depth analysis of a case can be based on the hypothesis that the case study will reveal trends or issues that have not been exposed in prior research or will reveal new and important implications for practice. For example, anecdotal evidence may suggest drug use among homeless veterans is related to their patterns of travel throughout the day. Assuming prior studies have not looked at individual travel choices as a way to study access to illicit drug use, a case study that observes a homeless veteran could reveal how issues of personal mobility choices facilitate regular access to illicit drugs. Note that it is important to conduct a thorough literature review to ensure that your assumption about the need to reveal new insights or previously hidden problems is valid and evidence-based.
  • The case challenges and offers a counter-point to prevailing assumptions? Over time, research on any given topic can fall into a trap of developing assumptions based on outdated studies that are still applied to new or changing conditions or the idea that something should simply be accepted as "common sense," even though the issue has not been thoroughly tested in current practice. A case study analysis may offer an opportunity to gather evidence that challenges prevailing assumptions about a research problem and provide a new set of recommendations applied to practice that have not been tested previously. For example, perhaps there has been a long practice among scholars to apply a particular theory in explaining the relationship between two subjects of analysis. Your case could challenge this assumption by applying an innovative theoretical framework [perhaps borrowed from another discipline] to explore whether this approach offers new ways of understanding the research problem. Taking a contrarian stance is one of the most important ways that new knowledge and understanding develops from existing literature.
  • The case provides an opportunity to pursue action leading to the resolution of a problem? Another way to think about choosing a case to study is to consider how the results from investigating a particular case may result in findings that reveal ways in which to resolve an existing or emerging problem. For example, studying the case of an unforeseen incident, such as a fatal accident at a railroad crossing, can reveal hidden issues that could be applied to preventative measures that contribute to reducing the chance of accidents in the future. In this example, a case study investigating the accident could lead to a better understanding of where to strategically locate additional signals at other railroad crossings so as to better warn drivers of an approaching train, particularly when visibility is hindered by heavy rain, fog, or at night.
  • The case offers a new direction in future research? A case study can be used as a tool for an exploratory investigation that highlights the need for further research about the problem. A case can be used when there are few studies that help predict an outcome or that establish a clear understanding about how best to proceed in addressing a problem. For example, after conducting a thorough literature review [very important!], you discover that little research exists showing the ways in which women contribute to promoting water conservation in rural communities of east central Africa. A case study of how women contribute to saving water in a rural village of Uganda can lay the foundation for understanding the need for more thorough research that documents how women in their roles as cooks and family caregivers think about water as a valuable resource within their community. This example of a case study could also point to the need for scholars to build new theoretical frameworks around the topic [e.g., applying feminist theories of work and family to the issue of water conservation].

Structure and Writing Style

The purpose of a paper in the social sciences designed around a case study is to thoroughly investigate a subject of analysis in order to reveal a new understanding about the research problem and, in so doing, contributing new knowledge to what is already known from previous studies. In applied social sciences disciplines [e.g., education, social work, public administration, etc.], case studies may also be used to reveal best practices, highlight key programs, or investigate interesting aspects of professional work.

In general, the structure of a case study research paper is not all that different from a standard college-level research paper. However, there are subtle differences you should be aware of. Here are the key elements to organizing and writing a case study research paper.

I.  Introduction

As with any research paper, your introduction should serve as a roadmap for your readers to ascertain the scope and purpose of your study . The introduction to a case study research paper, however, should not only describe the research problem and its significance, but you should also succinctly describe why the case is being used and how it relates to addressing the problem. The two elements should be linked. With this in mind, a good introduction answers these four questions:

  • What is being studied? Describe the research problem and describe the subject of analysis [the case] you have chosen to address the problem. Explain how they are linked and what elements of the case will help to expand knowledge and understanding about the problem.
  • Why is this topic important to investigate? Describe the significance of the research problem and state why a case study design and the subject of analysis that the paper is designed around is appropriate in addressing the problem.
  • What did we know about this topic before I did this study? Provide background that helps lead the reader into the more in-depth literature review to follow. If applicable, summarize prior case study research applied to the research problem and why it fails to adequately address the problem. Describe why your case will be useful. If no prior case studies have been used to address the research problem, explain why you have selected this subject of analysis.
  • How will this study advance new knowledge or new ways of understanding? Explain why your case study will be suitable in helping to expand knowledge and understanding about the research problem.

Each of these questions should be addressed in no more than a few paragraphs. Exceptions to this can be when you are addressing a complex research problem or subject of analysis that requires more in-depth background information.

II.  Literature Review

The literature review for a case study research paper is generally structured the same as it is for any college-level research paper. The difference, however, is that the literature review is focused on providing background information and  enabling historical interpretation of the subject of analysis in relation to the research problem the case is intended to address . This includes synthesizing studies that help to:

  • Place relevant works in the context of their contribution to understanding the case study being investigated . This would involve summarizing studies that have used a similar subject of analysis to investigate the research problem. If there is literature using the same or a very similar case to study, you need to explain why duplicating past research is important [e.g., conditions have changed; prior studies were conducted long ago, etc.].
  • Describe the relationship each work has to the others under consideration that informs the reader why this case is applicable . Your literature review should include a description of any works that support using the case to investigate the research problem and the underlying research questions.
  • Identify new ways to interpret prior research using the case study . If applicable, review any research that has examined the research problem using a different research design. Explain how your use of a case study design may reveal new knowledge or a new perspective or that can redirect research in an important new direction.
  • Resolve conflicts amongst seemingly contradictory previous studies . This refers to synthesizing any literature that points to unresolved issues of concern about the research problem and describing how the subject of analysis that forms the case study can help resolve these existing contradictions.
  • Point the way in fulfilling a need for additional research . Your review should examine any literature that lays a foundation for understanding why your case study design and the subject of analysis around which you have designed your study may reveal a new way of approaching the research problem or offer a perspective that points to the need for additional research.
  • Expose any gaps that exist in the literature that the case study could help to fill . Summarize any literature that not only shows how your subject of analysis contributes to understanding the research problem, but how your case contributes to a new way of understanding the problem that prior research has failed to do.
  • Locate your own research within the context of existing literature [very important!] . Collectively, your literature review should always place your case study within the larger domain of prior research about the problem. The overarching purpose of reviewing pertinent literature in a case study paper is to demonstrate that you have thoroughly identified and synthesized prior studies in relation to explaining the relevance of the case in addressing the research problem.

III.  Method

In this section, you explain why you selected a particular case [i.e., subject of analysis] and the strategy you used to identify and ultimately decide that your case was appropriate in addressing the research problem. The way you describe the methods used varies depending on the type of subject of analysis that constitutes your case study.

If your subject of analysis is an incident or event . In the social and behavioral sciences, the event or incident that represents the case to be studied is usually bounded by time and place, with a clear beginning and end and with an identifiable location or position relative to its surroundings. The subject of analysis can be a rare or critical event or it can focus on a typical or regular event. The purpose of studying a rare event is to illuminate new ways of thinking about the broader research problem or to test a hypothesis. Critical incident case studies must describe the method by which you identified the event and explain the process by which you determined the validity of this case to inform broader perspectives about the research problem or to reveal new findings. However, the event does not have to be a rare or uniquely significant to support new thinking about the research problem or to challenge an existing hypothesis. For example, Walo, Bull, and Breen conducted a case study to identify and evaluate the direct and indirect economic benefits and costs of a local sports event in the City of Lismore, New South Wales, Australia. The purpose of their study was to provide new insights from measuring the impact of a typical local sports event that prior studies could not measure well because they focused on large "mega-events." Whether the event is rare or not, the methods section should include an explanation of the following characteristics of the event: a) when did it take place; b) what were the underlying circumstances leading to the event; and, c) what were the consequences of the event in relation to the research problem.

If your subject of analysis is a person. Explain why you selected this particular individual to be studied and describe what experiences they have had that provide an opportunity to advance new understandings about the research problem. Mention any background about this person which might help the reader understand the significance of their experiences that make them worthy of study. This includes describing the relationships this person has had with other people, institutions, and/or events that support using them as the subject for a case study research paper. It is particularly important to differentiate the person as the subject of analysis from others and to succinctly explain how the person relates to examining the research problem [e.g., why is one politician in a particular local election used to show an increase in voter turnout from any other candidate running in the election]. Note that these issues apply to a specific group of people used as a case study unit of analysis [e.g., a classroom of students].

If your subject of analysis is a place. In general, a case study that investigates a place suggests a subject of analysis that is unique or special in some way and that this uniqueness can be used to build new understanding or knowledge about the research problem. A case study of a place must not only describe its various attributes relevant to the research problem [e.g., physical, social, historical, cultural, economic, political], but you must state the method by which you determined that this place will illuminate new understandings about the research problem. It is also important to articulate why a particular place as the case for study is being used if similar places also exist [i.e., if you are studying patterns of homeless encampments of veterans in open spaces, explain why you are studying Echo Park in Los Angeles rather than Griffith Park?]. If applicable, describe what type of human activity involving this place makes it a good choice to study [e.g., prior research suggests Echo Park has more homeless veterans].

If your subject of analysis is a phenomenon. A phenomenon refers to a fact, occurrence, or circumstance that can be studied or observed but with the cause or explanation to be in question. In this sense, a phenomenon that forms your subject of analysis can encompass anything that can be observed or presumed to exist but is not fully understood. In the social and behavioral sciences, the case usually focuses on human interaction within a complex physical, social, economic, cultural, or political system. For example, the phenomenon could be the observation that many vehicles used by ISIS fighters are small trucks with English language advertisements on them. The research problem could be that ISIS fighters are difficult to combat because they are highly mobile. The research questions could be how and by what means are these vehicles used by ISIS being supplied to the militants and how might supply lines to these vehicles be cut off? How might knowing the suppliers of these trucks reveal larger networks of collaborators and financial support? A case study of a phenomenon most often encompasses an in-depth analysis of a cause and effect that is grounded in an interactive relationship between people and their environment in some way.

NOTE:   The choice of the case or set of cases to study cannot appear random. Evidence that supports the method by which you identified and chose your subject of analysis should clearly support investigation of the research problem and linked to key findings from your literature review. Be sure to cite any studies that helped you determine that the case you chose was appropriate for examining the problem.

IV.  Discussion

The main elements of your discussion section are generally the same as any research paper, but centered around interpreting and drawing conclusions about the key findings from your analysis of the case study. Note that a general social sciences research paper may contain a separate section to report findings. However, in a paper designed around a case study, it is common to combine a description of the results with the discussion about their implications. The objectives of your discussion section should include the following:

Reiterate the Research Problem/State the Major Findings Briefly reiterate the research problem you are investigating and explain why the subject of analysis around which you designed the case study were used. You should then describe the findings revealed from your study of the case using direct, declarative, and succinct proclamation of the study results. Highlight any findings that were unexpected or especially profound.

Explain the Meaning of the Findings and Why They are Important Systematically explain the meaning of your case study findings and why you believe they are important. Begin this part of the section by repeating what you consider to be your most important or surprising finding first, then systematically review each finding. Be sure to thoroughly extrapolate what your analysis of the case can tell the reader about situations or conditions beyond the actual case that was studied while, at the same time, being careful not to misconstrue or conflate a finding that undermines the external validity of your conclusions.

Relate the Findings to Similar Studies No study in the social sciences is so novel or possesses such a restricted focus that it has absolutely no relation to previously published research. The discussion section should relate your case study results to those found in other studies, particularly if questions raised from prior studies served as the motivation for choosing your subject of analysis. This is important because comparing and contrasting the findings of other studies helps support the overall importance of your results and it highlights how and in what ways your case study design and the subject of analysis differs from prior research about the topic.

Consider Alternative Explanations of the Findings Remember that the purpose of social science research is to discover and not to prove. When writing the discussion section, you should carefully consider all possible explanations revealed by the case study results, rather than just those that fit your hypothesis or prior assumptions and biases. Be alert to what the in-depth analysis of the case may reveal about the research problem, including offering a contrarian perspective to what scholars have stated in prior research if that is how the findings can be interpreted from your case.

Acknowledge the Study's Limitations You can state the study's limitations in the conclusion section of your paper but describing the limitations of your subject of analysis in the discussion section provides an opportunity to identify the limitations and explain why they are not significant. This part of the discussion section should also note any unanswered questions or issues your case study could not address. More detailed information about how to document any limitations to your research can be found here .

Suggest Areas for Further Research Although your case study may offer important insights about the research problem, there are likely additional questions related to the problem that remain unanswered or findings that unexpectedly revealed themselves as a result of your in-depth analysis of the case. Be sure that the recommendations for further research are linked to the research problem and that you explain why your recommendations are valid in other contexts and based on the original assumptions of your study.

V.  Conclusion

As with any research paper, you should summarize your conclusion in clear, simple language; emphasize how the findings from your case study differs from or supports prior research and why. Do not simply reiterate the discussion section. Provide a synthesis of key findings presented in the paper to show how these converge to address the research problem. If you haven't already done so in the discussion section, be sure to document the limitations of your case study and any need for further research.

The function of your paper's conclusion is to: 1) reiterate the main argument supported by the findings from your case study; 2) state clearly the context, background, and necessity of pursuing the research problem using a case study design in relation to an issue, controversy, or a gap found from reviewing the literature; and, 3) provide a place to persuasively and succinctly restate the significance of your research problem, given that the reader has now been presented with in-depth information about the topic.

Consider the following points to help ensure your conclusion is appropriate:

  • If the argument or purpose of your paper is complex, you may need to summarize these points for your reader.
  • If prior to your conclusion, you have not yet explained the significance of your findings or if you are proceeding inductively, use the conclusion of your paper to describe your main points and explain their significance.
  • Move from a detailed to a general level of consideration of the case study's findings that returns the topic to the context provided by the introduction or within a new context that emerges from your case study findings.

Note that, depending on the discipline you are writing in or the preferences of your professor, the concluding paragraph may contain your final reflections on the evidence presented as it applies to practice or on the essay's central research problem. However, the nature of being introspective about the subject of analysis you have investigated will depend on whether you are explicitly asked to express your observations in this way.

Problems to Avoid

Overgeneralization One of the goals of a case study is to lay a foundation for understanding broader trends and issues applied to similar circumstances. However, be careful when drawing conclusions from your case study. They must be evidence-based and grounded in the results of the study; otherwise, it is merely speculation. Looking at a prior example, it would be incorrect to state that a factor in improving girls access to education in Azerbaijan and the policy implications this may have for improving access in other Muslim nations is due to girls access to social media if there is no documentary evidence from your case study to indicate this. There may be anecdotal evidence that retention rates were better for girls who were engaged with social media, but this observation would only point to the need for further research and would not be a definitive finding if this was not a part of your original research agenda.

Failure to Document Limitations No case is going to reveal all that needs to be understood about a research problem. Therefore, just as you have to clearly state the limitations of a general research study , you must describe the specific limitations inherent in the subject of analysis. For example, the case of studying how women conceptualize the need for water conservation in a village in Uganda could have limited application in other cultural contexts or in areas where fresh water from rivers or lakes is plentiful and, therefore, conservation is understood more in terms of managing access rather than preserving access to a scarce resource.

Failure to Extrapolate All Possible Implications Just as you don't want to over-generalize from your case study findings, you also have to be thorough in the consideration of all possible outcomes or recommendations derived from your findings. If you do not, your reader may question the validity of your analysis, particularly if you failed to document an obvious outcome from your case study research. For example, in the case of studying the accident at the railroad crossing to evaluate where and what types of warning signals should be located, you failed to take into consideration speed limit signage as well as warning signals. When designing your case study, be sure you have thoroughly addressed all aspects of the problem and do not leave gaps in your analysis that leave the reader questioning the results.

Writing Tip

At Least Five Misconceptions about Case Study Research

Social science case studies are often perceived as limited in their ability to create new knowledge because they are not randomly selected and findings cannot be generalized to larger populations. Flyvbjerg examines five misunderstandings about case study research and systematically "corrects" each one. To quote, these are:

Misunderstanding 1 :  General, theoretical [context-independent] knowledge is more valuable than concrete, practical [context-dependent] knowledge. Misunderstanding 2 :  One cannot generalize on the basis of an individual case; therefore, the case study cannot contribute to scientific development. Misunderstanding 3 :  The case study is most useful for generating hypotheses; that is, in the first stage of a total research process, whereas other methods are more suitable for hypotheses testing and theory building. Misunderstanding 4 :  The case study contains a bias toward verification, that is, a tendency to confirm the researcher’s preconceived notions. Misunderstanding 5 :  It is often difficult to summarize and develop general propositions and theories on the basis of specific case studies [p. 221].

While writing your paper, think introspectively about how you addressed these misconceptions because to do so can help you strengthen the validity and reliability of your research by clarifying issues of case selection, the testing and challenging of existing assumptions, the interpretation of key findings, and the summation of case outcomes. Think of a case study research paper as a complete, in-depth narrative about the specific properties and key characteristics of your subject of analysis applied to the research problem.

How To Write a Psychology Case Study in 8 Steps (Plus Tips)

We bet you may be familiar with what a case study is if you are a psychology, sociology, or anthropology student, depending on what you study in college. This research technique is employed to examine a specific individual, group, or circumstance. This tutorial from our dissertation writing services will teach you how to write a case study effectively, from conducting research to properly citing sources. Additionally, we will examine various case study types and provide examples for you so that you have no further questions.

  • Gather information to create a profile for a subject. …
  • Choose a case study method. …
  • Collect information regarding the subject’s background. …
  • Describe the subject’s symptoms or problems. …
  • Analyze the data and establish a diagnosis. …
  • Choose a treatment approach.

Why are psychology case studies important?

Case studies in psychology are crucial because they can be used to develop treatments, validate diagnoses, and provide evidence to support psychological theories. They can also enable future psychologists to review additional comprehensive empirical research to broaden their own case study investigations. The comparison of information from earlier case studies can aid future research development procedures.

What is a psychology case study?

A psychology case study is a comprehensive examination of a single individual, group of people, or event that draws on data from experiments, observations, and other sources. Psychologists gather data for a case study through experimentation, interviews, observation, psychometric testing, and case study archives. These studies typically investigate psychological mechanisms and behaviors to gather knowledge for subsequent investigations into a condition or behavior. Sometimes, a case study will look at every aspect of a person’s life and behavior.

Benefits of psychology case studies

Here are some common benefits of a psychology case study:

Types of psychology case studies

A research psychologist may choose to conduct one of the following six types of case studies:

How to write a psychology case study

If you’re considering writing your own case study, here are eight steps to get you started:

1. Gather information to create a profile for a subject

Before creating research methods and a hypothesis, it’s critical to gain as much knowledge as you can about the research topic. You can use prior case studies as supplementary data to conduct and better understand theories or information during your case study research. After gathering data from earlier studies, gather data on the topic from the following four sources:

2. Choose a case study method

When creating a psychology case study, there are two approaches to consider: the prospective approach and the retrospective approach. To choose the best approach, take into account the case study’s focus and the research you hope to uncover. In a prospective case study, the goal is to observe a person or group in order to identify and comprehend the psychological outcomes. Retrospective case studies analyze past events, such as a subject’s diagnosis, to identify potential influences on a subject’s psychological well-being and past behaviors.

3. Collect information regarding the subjects background

The subject’s history or background is presented in the first section of a case study. In this section, a research psychologist collects the following information:

4. Describe the subjects symptoms or problems

Include any mental, bodily, or sensory symptoms a subject may have in order to create an effective treatment plan. Including in your study any thoughts, emotions, or worries the subject has regarding their symptoms is beneficial. If the subject is tested, describe all results and evaluations that are pertinent to the case study.

5. Analyze the data and establish a diagnosis

This step entails analyzing and choosing the best diagnosis for the subject based on the information from your research. Explain each step of your research methods, as well as the symptoms of your subject, to provide evidence to support your diagnosis. Additionally, symptoms may serve as evidence that a person meets the requirements for a particular disorder.

6. Choose a treatment approach

Once you have reached a diagnosis, the following step in writing a psychology case study is to select a treatment strategy. Here are four treatment approaches you may decide to use:

7. Describe treatment goals and processes

Define the objectives of using this treatment, how you intend to use it, and any outcomes you anticipate occurring after treatment after choosing a treatment approach. Some objectives might be to completely eradicate symptoms or use the therapy to lessen some symptoms and implement coping mechanisms so the patient can resume a normal life. To provide more details on the diagnosis for future research, it’s crucial to record your treatment procedures and keep track of how the subject responds to them.

8. Write a discussion section

The discussion section appears as the final section of a psychology case study. You must describe all case study procedures, outcomes, and components in this section, along with any restrictions and how the study adds to prior research. This section also contains any psychological conclusions or hypotheses that may need additional study. You have the chance to review every aspect of your study in the discussion section and assess its accuracy, potential contributions to future research, and potential therapeutic strategies a psychologist might employ with a different patient who shares your history and symptoms.

15 Famous Experiments and Case Studies in Psychology

psychology theories, explained below

Psychology has seen thousands upon thousands of research studies over the years. Most of these studies have helped shape our current understanding of human thoughts, behavior, and feelings.

The psychology case studies in this list are considered classic examples of psychological case studies and experiments, which are still being taught in introductory psychology courses up to this day.

Some studies, however, were downright shocking and controversial that you’d probably wonder why such studies were conducted back in the day. Imagine participating in an experiment for a small reward or extra class credit, only to be left scarred for life. These kinds of studies, however, paved the way for a more ethical approach to studying psychology and implementation of research standards such as the use of debriefing in psychology research .

Case Study vs. Experiment

Before we dive into the list of the most famous studies in psychology, let us first review the difference between case studies and experiments.

  • It is an in-depth study and analysis of an individual, group, community, or phenomenon. The results of a case study cannot be applied to the whole population, but they can provide insights for further studies.
  • It often uses qualitative research methods such as observations, surveys, and interviews.
  • It is often conducted in real-life settings rather than in controlled environments.
  • An experiment is a type of study done on a sample or group of random participants, the results of which can be generalized to the whole population.
  • It often uses quantitative research methods that rely on numbers and statistics.
  • It is conducted in controlled environments, wherein some things or situations are manipulated.

Famous Experiments in Psychology

1. the marshmallow experiment.

Psychologist Walter Mischel conducted the marshmallow experiment at Stanford University in the 1960s to early 1970s. It was a simple test that aimed to define the connection between delayed gratification and success in life.

The instructions were fairly straightforward: children ages 4-6 were presented a piece of marshmallow on a table and they were told that they would receive a second piece if they could wait for 15 minutes without eating the first marshmallow.

About one-third of the 600 participants succeeded in delaying gratification to receive the second marshmallow. Mischel and his team followed up on these participants in the 1990s, learning that those who had the willpower to wait for a larger reward experienced more success in life in terms of SAT scores and other metrics.

This case study also supported self-control theory , a theory in criminology that holds that people with greater self-control are less likely to end up in trouble with the law!

The classic marshmallow experiment, however, was debunked in a 2018 replication study done by Tyler Watts and colleagues.

This more recent experiment had a larger group of participants (900) and a better representation of the general population when it comes to race and ethnicity. In this study, the researchers found out that the ability to wait for a second marshmallow does not depend on willpower alone but more so on the economic background and social status of the participants.

2. The Bystander Effect

In 1694, Kitty Genovese was murdered in the neighborhood of Kew Gardens, New York. It was told that there were up to 38 witnesses and onlookers in the vicinity of the crime scene, but nobody did anything to stop the murder or call for help.

Such tragedy was the catalyst that inspired social psychologists Bibb Latane and John Darley to formulate the phenomenon called bystander effect or bystander apathy .

Subsequent investigations showed that this story was exaggerated and inaccurate, as there were actually only about a dozen witnesses, at least two of whom called the police. But the case of Kitty Genovese led to various studies that aim to shed light on the bystander phenomenon.

Latane and Darley tested bystander intervention in an experimental study . Participants were asked to answer a questionnaire inside a room, and they would either be alone or with two other participants (who were actually actors or confederates in the study). Smoke would then come out from under the door. The reaction time of participants was tested — how long would it take them to report the smoke to the authorities or the experimenters?

The results showed that participants who were alone in the room reported the smoke faster than participants who were with two passive others. The study suggests that the more onlookers are present in an emergency situation, the less likely someone would step up to help, a social phenomenon now popularly called the bystander effect.

3. Asch Conformity Study

Have you ever made a decision against your better judgment just to fit in with your friends or family? The Asch Conformity Studies will help you understand this kind of situation better.

In this experiment, a group of participants were shown three numbered lines of different lengths and asked to identify the longest of them all. However, only one true participant was present in every group and the rest were actors, most of whom told the wrong answer.

Results showed that the participants went for the wrong answer, even though they knew which line was the longest one in the first place. When the participants were asked why they identified the wrong one, they said that they didn’t want to be branded as strange or peculiar.

This study goes to show that there are situations in life when people prefer fitting in than being right. It also tells that there is power in numbers — a group’s decision can overwhelm a person and make them doubt their judgment.

4. The Bobo Doll Experiment

The Bobo Doll Experiment was conducted by Dr. Albert Bandura, the proponent of social learning theory .

Back in the 1960s, the Nature vs. Nurture debate was a popular topic among psychologists. Bandura contributed to this discussion by proposing that human behavior is mostly influenced by environmental rather than genetic factors.

In the Bobo Doll Experiment, children were divided into three groups: one group was shown a video in which an adult acted aggressively toward the Bobo Doll, the second group was shown a video in which an adult play with the Bobo Doll, and the third group served as the control group where no video was shown.

The children were then led to a room with different kinds of toys, including the Bobo Doll they’ve seen in the video. Results showed that children tend to imitate the adults in the video. Those who were presented the aggressive model acted aggressively toward the Bobo Doll while those who were presented the passive model showed less aggression.

While the Bobo Doll Experiment can no longer be replicated because of ethical concerns, it has laid out the foundations of social learning theory and helped us understand the degree of influence adult behavior has on children.

5. Blue Eye / Brown Eye Experiment

Following the assassination of Martin Luther King Jr. in 1968, third-grade teacher Jane Elliott conducted an experiment in her class. Although not a formal experiment in controlled settings, A Class Divided is a good example of a social experiment to help children understand the concept of racism and discrimination.

The class was divided into two groups: blue-eyed children and brown-eyed children. For one day, Elliott gave preferential treatment to her blue-eyed students, giving them more attention and pampering them with rewards. The next day, it was the brown-eyed students’ turn to receive extra favors and privileges.

As a result, whichever group of students was given preferential treatment performed exceptionally well in class, had higher quiz scores, and recited more frequently; students who were discriminated against felt humiliated, answered poorly in tests, and became uncertain with their answers in class.

This study is now widely taught in sociocultural psychology classes.

6. Stanford Prison Experiment

One of the most controversial and widely-cited studies in psychology is the Stanford Prison Experiment , conducted by Philip Zimbardo at the basement of the Stanford psychology building in 1971. The hypothesis was that abusive behavior in prisons is influenced by the personality traits of the prisoners and prison guards.

The participants in the experiment were college students who were randomly assigned as either a prisoner or a prison guard. The prison guards were then told to run the simulated prison for two weeks. However, the experiment had to be stopped in just 6 days.

The prison guards abused their authority and harassed the prisoners through verbal and physical means. The prisoners, on the other hand, showed submissive behavior. Zimbardo decided to stop the experiment because the prisoners were showing signs of emotional and physical breakdown.

Although the experiment wasn’t completed, the results strongly showed that people can easily get into a social role when others expect them to, especially when it’s highly stereotyped .

7. The Halo Effect

Have you ever wondered why toothpastes and other dental products are endorsed in advertisements by celebrities more often than dentists? The Halo Effect is one of the reasons!

The Halo Effect shows how one favorable attribute of a person can gain them positive perceptions in other attributes. In the case of product advertisements, attractive celebrities are also perceived as intelligent and knowledgeable of a certain subject matter even though they’re not technically experts.

The Halo Effect originated in a classic study done by Edward Thorndike in the early 1900s. He asked military commanding officers to rate their subordinates based on different qualities, such as physical appearance, leadership, dependability, and intelligence.

The results showed that high ratings of a particular quality influences the ratings of other qualities, producing a halo effect of overall high ratings. The opposite also applied, which means that a negative rating in one quality also correlated to negative ratings in other qualities.

Experiments on the Halo Effect came in various formats as well, supporting Thorndike’s original theory. This phenomenon suggests that our perception of other people’s overall personality is hugely influenced by a quality that we focus on.

8. Cognitive Dissonance

There are experiences in our lives when our beliefs and behaviors do not align with each other and we try to justify them in our minds. This is cognitive dissonance , which was studied in an experiment by Leon Festinger and James Carlsmith back in 1959.

In this experiment, participants had to go through a series of boring and repetitive tasks, such as spending an hour turning pegs in a wooden knob. After completing the tasks, they were then paid either $1 or $20 to tell the next participants that the tasks were extremely fun and enjoyable. Afterwards, participants were asked to rate the experiment. Those who were given $1 rated the experiment as more interesting and fun than those who received $20.

The results showed that those who received a smaller incentive to lie experienced cognitive dissonance — $1 wasn’t enough incentive for that one hour of painstakingly boring activity, so the participants had to justify that they had fun anyway.

Famous Case Studies in Psychology

9. little albert.

In 1920, behaviourist theorists John Watson and Rosalie Rayner experimented on a 9-month-old baby to test the effects of classical conditioning in instilling fear in humans.

This was such a controversial study that it gained popularity in psychology textbooks and syllabi because it is a classic example of unethical research studies done in the name of science.

In one of the experiments, Little Albert was presented with a harmless stimulus or object, a white rat, which he wasn’t scared of at first. But every time Little Albert would see the white rat, the researchers would play a scary sound of hammer and steel. After about 6 pairings, Little Albert learned to fear the rat even without the scary sound.

Little Albert developed signs of fear to different objects presented to him through classical conditioning . He even generalized his fear to other stimuli not present in the course of the experiment.

10. Phineas Gage

Phineas Gage is such a celebrity in Psych 101 classes, even though the way he rose to popularity began with a tragic accident. He was a resident of Central Vermont and worked in the construction of a new railway line in the mid-1800s. One day, an explosive went off prematurely, sending a tamping iron straight into his face and through his brain.

Gage survived the accident, fortunately, something that is considered a feat even up to this day. He managed to find a job as a stagecoach after the accident. However, his family and friends reported that his personality changed so much that “he was no longer Gage” (Harlow, 1868).

New evidence on the case of Phineas Gage has since come to light, thanks to modern scientific studies and medical tests. However, there are still plenty of mysteries revolving around his brain damage and subsequent recovery.

11. Anna O.

Anna O., a social worker and feminist of German Jewish descent, was one of the first patients to receive psychoanalytic treatment.

Her real name was Bertha Pappenheim and she inspired much of Sigmund Freud’s works and books on psychoanalytic theory, although they hadn’t met in person. Their connection was through Joseph Breuer, Freud’s mentor when he was still starting his clinical practice.

Anna O. suffered from paralysis, personality changes, hallucinations, and rambling speech, but her doctors could not find the cause. Joseph Breuer was then called to her house for intervention and he performed psychoanalysis, also called the “talking cure”, on her.

Breuer would tell Anna O. to say anything that came to her mind, such as her thoughts, feelings, and childhood experiences. It was noted that her symptoms subsided by talking things out.

However, Breuer later referred Anna O. to the Bellevue Sanatorium, where she recovered and set out to be a renowned writer and advocate of women and children.

12. Patient HM

H.M., or Henry Gustav Molaison, was a severe amnesiac who had been the subject of countless psychological and neurological studies.

Henry was 27 when he underwent brain surgery to cure the epilepsy that he had been experiencing since childhood. In an unfortunate turn of events, he lost his memory because of the surgery and his brain also became unable to store long-term memories.

He was then regarded as someone living solely in the present, forgetting an experience as soon as it happened and only remembering bits and pieces of his past. Over the years, his amnesia and the structure of his brain had helped neuropsychologists learn more about cognitive functions .

Suzanne Corkin, a researcher, writer, and good friend of H.M., recently published a book about his life. Entitled Permanent Present Tense , this book is both a memoir and a case study following the struggles and joys of Henry Gustav Molaison.

13. Chris Sizemore

Chris Sizemore gained celebrity status in the psychology community when she was diagnosed with multiple personality disorder, now known as dissociative identity disorder.

Sizemore has several alter egos, which included Eve Black, Eve White, and Jane. Various papers about her stated that these alter egos were formed as a coping mechanism against the traumatic experiences she underwent in her childhood.

Sizemore said that although she has succeeded in unifying her alter egos into one dominant personality, there were periods in the past experienced by only one of her alter egos. For example, her husband married her Eve White alter ego and not her.

Her story inspired her psychiatrists to write a book about her, entitled The Three Faces of Eve , which was then turned into a 1957 movie of the same title.

14. David Reimer

When David was just 8 months old, he lost his penis because of a botched circumcision operation.

Psychologist John Money then advised Reimer’s parents to raise him as a girl instead, naming him Brenda. His gender reassignment was supported by subsequent surgery and hormonal therapy.

Money described Reimer’s gender reassignment as a success, but problems started to arise as Reimer was growing up. His boyishness was not completely subdued by the hormonal therapy. When he was 14 years old, he learned about the secrets of his past and he underwent gender reassignment to become male again.

Reimer became an advocate for children undergoing the same difficult situation he had been. His life story ended when he was 38 as he took his own life.

15. Kim Peek

Kim Peek was the inspiration behind Rain Man , an Oscar-winning movie about an autistic savant character played by Dustin Hoffman.

The movie was released in 1988, a time when autism wasn’t widely known and acknowledged yet. So it was an eye-opener for many people who watched the film.

In reality, Kim Peek was a non-autistic savant. He was exceptionally intelligent despite the brain abnormalities he was born with. He was like a walking encyclopedia, knowledgeable about travel routes, US zip codes, historical facts, and classical music. He also read and memorized approximately 12,000 books in his lifetime.

This list of experiments and case studies in psychology is just the tip of the iceberg! There are still countless interesting psychology studies that you can explore if you want to learn more about human behavior and dynamics.

You can also conduct your own mini-experiment or participate in a study conducted in your school or neighborhood. Just remember that there are ethical standards to follow so as not to repeat the lasting physical and emotional harm done to Little Albert or the Stanford Prison Experiment participants.

Case study definition

case study information psychology

Case study, a term which some of you may know from the "Case Study of Vanitas" anime and manga, is a thorough examination of a particular subject, such as a person, group, location, occasion, establishment, phenomena, etc. They are most frequently utilized in research of business, medicine, education and social behaviour. There are a different types of case studies that researchers might use:

• Collective case studies

• Descriptive case studies

• Explanatory case studies

• Exploratory case studies

• Instrumental case studies

• Intrinsic case studies

Case studies are usually much more sophisticated and professional than regular essays and courseworks, as they require a lot of verified data, are research-oriented and not necessarily designed to be read by the general public.

How to write a case study?

It very much depends on the topic of your case study, as a medical case study and a coffee business case study have completely different sources, outlines, target demographics, etc. But just for this example, let's outline a coffee roaster case study. Firstly, it's likely going to be a problem-solving case study, like most in the business and economics field are. Here are some tips for these types of case studies:

• Your case scenario should be precisely defined in terms of your unique assessment criteria.

• Determine the primary issues by analyzing the scenario. Think about how they connect to the main ideas and theories in your piece.

• Find and investigate any theories or methods that might be relevant to your case.

• Keep your audience in mind. Exactly who are your stakeholder(s)? If writing a case study on coffee roasters, it's probably gonna be suppliers, landlords, investors, customers, etc.

• Indicate the best solution(s) and how they should be implemented. Make sure your suggestions are grounded in pertinent theories and useful resources, as well as being realistic, practical, and attainable.

• Carefully proofread your case study. Keep in mind these four principles when editing: clarity, honesty, reality and relevance.

Experimental Psychology Seminar - John Greenwood, UCL

23 April 2024–24 April 2024, 12:30 pm–3:00 pm

JohnGreenwood_EPseminar

John Greenwood will present research demonstrating how crowding—where clutter merges visual elements—affects both peripheral and foveal vision. His studies illustrate similar error patterns in the typical vision and in conditions like amblyopia, suggesting that these effects are governed by 'pooling' models. These models propose that crowding simplifies visual scenes into a general 'gist', reducing the demand on neural resources. This research extends to how crowding independently affects color and motion judgments, offering insights into the visual system's multifaceted response to clutter.

Event Information

Venue: Room 313, 26 Bedford Way.

A buffet lunch will be available just before the talk at 12.30pm in room 313BW.

You may also attend virtually via zoom:  https://ucl.zoom.us/j/91768876812?pwd=aExJVmFTZnBZZCtFbmlGS0tSY2VCdz09 Meeting ID: 917 6887 6812 Passcode: 950231 Title: Using typical vision to understand clinical disorders of vision

Abstract: Our ability to recognise objects in the world is impaired in cluttered environments, even for objects that are clearly visible in isolation. This process, known as crowding , presents the fundamental limit on our peripheral vision. These disruptive effects are elevated in foveal vision (the centre of our gaze) during development, and further elevated in clinical disorders including amblyopia (‘lazy eye’) and nystagmus (uncontrolled eye movements), placing a limit on everyday tasks like reading.

Can we understand the mechanisms underlying these elevations using crowding in the typical periphery? I will first show that crowding produces the same kinds of errors in peripheral vision as in the foveal vision of typical and amblyopic children. These errors are well described in all cases by ‘pooling’ models that depict crowding as an unwanted combination of cluttered elements. In peripheral vision, crowding can also independently disrupt judgements of colour and motion for the same target object, suggesting the existence of multiple instances of crowding throughout the visual system. Dissociations between the crowding of colour and motion are similarly evident in amblyopic vision. Together, our findings depict crowding as a process that simplifies the visual scene to provide a ‘gist’ that can be efficiently encoded with reduced neural resources.

About the Speaker

John greenwood.

Associate Professor in Experimental Psychology at Experimental Psychology, UCL

I am Associate Professor in Experimental Psychology at University College London, working on visual perception. My lab examines spatial vision and 'crowding' in both typical peripheral vision and in clinical disorders such as amblyopia and nystagmus, as well as face recognition, visual imagery and hallucinations, and the perception of visual dimensions including motion, depth, and position. I joined the department in 2013 with a Career Development Award from the Medical Research Council, having previously undertaken postdoctoral research at the Institute of Ophthalmology at University College London (London, UK) with Prof. Steven Dakin and Dr. Peter Bex from 2008-2010, and at the Laboratoire Psychologie de la Perception of the Université Paris Descartes (Paris, France) with Patrick Cavanagh from 2011-2013. My Ph.D. was completed in 2007 at the School of Psychology of the Australian National University (Canberra, Australia), with Dr. Mark Edwards.

Case Study: How Aggressively Should a Bank Pursue AI?

  • Thomas H. Davenport
  • George Westerman

case study information psychology

A Malaysia-based CEO weighs the risks and potential benefits of turning a traditional bank into an AI-first institution.

Siti Rahman, the CEO of Malaysia-based NVF Bank, faces a pivotal decision. Her head of AI innovation, a recent recruit from Google, has a bold plan. It requires a substantial investment but aims to transform the traditional bank into an AI-first institution, substantially reducing head count and the number of branches. The bank’s CFO worries they are chasing the next hype cycle and cautions against valuing efficiency above all else. Siti must weigh the bank’s mixed history with AI, the resistance to losing the human touch in banking services, and the risks of falling behind in technology against the need for a prudent, incremental approach to innovation.

Two experts offer advice: Noemie Ellezam-Danielo, the chief digital and AI strategy at Société Générale, and Sastry Durvasula, the chief information and client services officer at TIAA.

Siti Rahman, the CEO of Malaysia-headquartered NVF Bank, hurried through the corridors of the university’s computer engineering department. She had directed her driver to the wrong building—thinking of her usual talent-recruitment appearances in the finance department—and now she was running late. As she approached the room, she could hear her head of AI innovation, Michael Lim, who had joined NVF from Google 18 months earlier, breaking the ice with the students. “You know, NVF used to stand for Never Very Fast,” he said to a few giggles. “But the bank is crawling into the 21st century.”
