What are headings?

Headings, sections, subsections, or levels of subordination are a style of dividing your research paper into major parts, then minor subsections. Most college papers do not need headings, especially if you are only producing two to five pages. However, if your professor requests you use headings or your are writing an especially long or detailed paper, then use headings to help readers navigate your text. Follow the APA style rules for creating the correct level of heading. Always start with a level one heading and drill down to the last subsection possible (five) in order as seen below. Instructions and examples for headings are available on p. 47- 49 of the new APA 7th Edition manual.

• Heading Levels Template: Student Paper APA Style 7th Edition This example student paper clearly illustrates how to style section headings including the paper title and the Introduction section (which should not be labeled Introduction as APA assumes all papers begin with an introduction section).

Proper Title Case vs. lowercase paragraph heading

Proper title case is using both uppercase and lowercase letters in a title. It calls for the major words to be capitalized while any small conjunctions are made smaller, i.e., 

The Title of this Paper is Lengthy

Lowercase paragraph heading calls for the first word to be capitalized along with any proper nouns contained within the heading, i.e., 

        The title of this heading is much shorter and all lowercase except for the first word.

7th Edition APA Style: How to Use APA Headings in Your Paper

APA headings and subheadings give your paper the structure it needs to differentiate and separate sections –  much like how we’ve structured this article.  Sounds simple, right? Not exactly. 

Like a reference list, in-text citations, footnotes, and abstract, APA headings require correct formatting. More so since the American Psychological Association (APA) released the 7th edition of their style guide. 

In this article, we’ll go through the different APA heading levels and their formats. You will also have access to APA headings examples and insight on  APA capitalization rules  so you can nail APA heading formatting without breaking a sweat. 

Table of Contents

What Are APA Headers? 

As mentioned earlier, APA headers separate and differentiate your paper’s sections. They are crucial in scholarly works because: 

• They give structure to your report. 
• Readers and your adviser or restructure can quickly identify the sections of your paper. 
• When properly formatted and used, they can provide a visual aid to improve the flow of information in your paper. 

The APA headers are divided into five levels (more on this later!).

APA 6th Edition vs. 7th Edition: Is There A Difference In Headings?  

Before diving down to APA’s unique headings system, let’s talk about the elephant in the room – the style guide edition. And, we hate to break it to you. There are a lot of changes between the APA 6th edition vs. 7th edition, but since we’re only talking about headings, we’re not going to outline all the differences. 

Luckily for you, there are not a lot of changes in the APA style 7th edition headings. 

• For the capitalization and style, you should write the headings in title case and boldface. 
• Formatting of the first level (main level of heading) and second level headings are almost identical to the 6th edition, except for the new title case and boldface rules. 
• The third, fourth, and fifth-level headings of the 7th edition APA are distinguished by using periods, indentation, and italics. 

To better understand these changes, you can refer to the table below.  

In addition to these formatting changes, the 7th APA style guide also dictates that student papers do not need a running head.

What Are the Different APA Heading Levels? 

Now that you know what APA headings are and the difference between the headings of APA 6th and 7th editions, let’s talk about the levels. 

APA headings levels are divided into five – Level 1, Level 2, Level 3, Level 4, and Level 5. In a hurry? You can check the comparison table below.

Expert Insight:  Title case means capitalizing the first letter of words with at least four or more letters. These words are typically proper nouns, pronouns, adverbs, nouns, and adjectives. However, keep in mind that the first word in a header is always in upper case, even if the first word is an article like “ the”  or  “a.”

Level 1 

Level 1, or the first level of heading, represents the main section of your paper. For instance, if your paper topic discusses the effects of social media platforms on university students, the header “Method” should be in level 1. 

In a 7th APA style, the structure should be:

The text after Level 1 will be a new paragraph and not on the same line as the heading. 

Expert Insight:  Does the Level 1 format look familiar? That’s because it has the same structure as the Paper Title element (APA 7 title page) in the APA cover page format.

What if the next portion of your paper discusses the sampling method you’ve used? In that case, the first level of subsection should be the second level of headings or simply Level 2. Why? This is because the “sampling method” is a cluster of the main level “Method.”

The structure of a Level 2 header is, however, different. Instead of having the “Sampling Method” centered, you’ll flush it to the left. A Level 2 header will be in bold, and the paragraph will start in a new line. 

Here’s how a Level 2 APA is formatted:

Tip:  When in doubt, remember that APA sub-headings or subsections should be related to the subsequent header.

Level 3 

The third level of headings, or Level 3, further expounds the information you’ve shared in Level 2 or “Sampling Method.” In this case, your level 3 will be “Procedure.”The formatting of Level 2 and Level 3 are pretty similar.

As a matter of fact, there is one key difference a Level 3 header will be in bold italic. The alignment, boldface, and title case will remain the same. 

You should format a Level 3 APA header like this:

Level 4 

You will need to use the fourth level of headings or Level 4 if there are other details from the Level 3 “Sampling Method” that you need to discuss further. In our APA example, that Level 4 will be the “Participant Recruitment.”

The format of Level 4 is distinct from levels 1, 2, and 3 because: 

• It is indented. 
• The paragraph is in line with the heading. 
• You will add a period at the end of the heading. 

To better understand an APA Level 4 heading format, here is an example:

You’ve probably caught on that Level 5 is a subheading of Level 4, and you are correct! If “Participant Recruitment” warrants more information, you can use the fifth level of headings for either “Tools” or “Compensation.”

The formatting of Level 5 is a bit similar to Level 4; the only difference is that you’ll use a boldface italic. Other elements like indent and period will remain the same. 

APA Heading Examples 

If you combine the levels, your paper should look like this:

How to Choose the Right APA Heading to Use?

With five levels to choose from, selecting which one you should use for your paper can be daunting. Here are some tips: 

• Use the Level 1 APA header when it is an important part of the paper. For instance, method, conclusion, and results. 
• Use the Level 2 heading when the subsections are related to the first level. 
• You should apply a Level 3 header when the APA subheadings are related to Level 2. 
• Level 4 headers should be used in your paper if the sections are directly correlated with Level 3. 
• Lastly, you should use Level 5 headers when the information is related to Level 4. 

How Do You Organize Headings in APA 7? 

Now that you are familiar with all the five-level headings in APA 7. The question now is, how do you arrange them? The rule of thumb for organizing APA 7 headers is to always start with Level 1, followed by subsequent headings of equal importance. 

Does that mean that the levels should only be used once? Not technically. You can have all the number of levels in a section as long as you follow the progression, wherein Level 1 always comes first. 

Tip:  Don’t mistake section labels and APA headings or vice versa. Section labels or special headings are different from regular headings. Not only are they formatted differently, but they also appear at the top section of the paper, below the pagination or page number. You will always find them at the start of a new page. 

Additional APA 7 Header Guidelines 

On top of the format or structure of the level headers, you should also watch out for the following: 

• Text, including the headers, should be double-spaced.
• Font size and typeface should stay consistent throughout your article. For instance, if you’ve used Times New Roman 12pt in your headers, the text should also have the same typeface and size. 
• Depending on your teacher’s requirements, you may or may not need labels (letter or number) for the headers. When in doubt, ask for clarification. 
• There should be at least two APA subheadings in your paper. If you only have one, consider adding more sections in your paper or use no subheadings at all. 

APA Headings FAQ

How to create table of contents in apa format.

In APA 7th edition, it is not required to have a table of contents, but in case your adviser requires one, you can easily do so whether you are using Google docs or Microsoft Word. 

In Google Docs: 

• Set the headers in the correct header size. Click the “Normal Text” dropdown and choose Header 1 for Level 1 APA headings, Header 2 for Level 2, and so on. 
• Go to Insert>Table of Contents. 

Note:  Keep in mind that APA 7th style guide dictates that the headings and text should have the same font size and typeface. So, after printing the table of contents, make sure to revert the levels to the correct size. 

In Microsoft Word: 

• Highlight the level heading 
• Select Update the Heading
• Match the heading size with the level heading. For instance, if you have a Level 1 Header, select Header 1. 
• Go to References > Table of Contents > Custom Table of Contents.  
• Input how many headings you will need. 

Tip:  Ensure you set the levels in the correct format before creating the table of contents. All levels no longer have a lower case heading. The only thing you should watch out for is the alignment, boldface, italics, and period.

Do You Have to Use All the APA Headers?

No, you don’t have to use all five APA headers in your paper. The headers and the number of subsections will highly depend on your writing style and subject matter. 

Is There an Introduction Heading? 

No, there isn’t an “introduction heading.” This is because the first paragraphs of a paper are already understood as the introduction section. 

Heading in the Right Direction 

The format of APA headings and subheadings can be confusing at first. But remember, APA capitalization rules for the 7th APA edition mean using title case for all heading levels; no more uppercase and lowercase headings. And you can distinguish the third, fourth, and fifth-level headings through italicization, period, and indentation. As for the text after the heading, only levels 4 and 5 will have the paragraph in line with the headings. 

Don’t forget that running headers are no longer required in student papers! But just to be on the safe side, make sure to always ask your instructor.

Headings are used to effectively organize ideas within a study or manuscript.  It can also highlight important items, themes or topics within sections.  By creating concise headings, the reader can anticipate key points and track the development of your argument.  The heading levels establish the hierarchy of each section and are designated by their formatting.

Adapted from American Psychological Association. (2009). Format for Five Levels of Heading in APA Journals. Publication manual of the American psychological association (6th ed., p. 62) Washington, D.C.: American Psychological Association.

• If you need to use subsections in any given section, use a least two, otherwise omit their use.
• Do not label headings with numbers or letters
• Use of title case : Use of both upper and lower case letters, all major words are capitalized
• Paragraph headings are immediately followed by text for that subsection, rather than starting on a new line.  The heading sits at the start of the first paragraph for that section.

There are five levels of headings available to use in an APA formatted paper. These headings indicate the hierchy of the information within the paper.

For example, if your paper contains the standard main sections Method , Results , and Discussion , these should all use the first-level heading.

• Method (level one)
• Results (level one)
• Discussion (level one)

If you want to include Participants and Instruments within the Method section, you would make these a level two heading.

• Participants (level two)
• Instruments (level two)

A subsection of Participants , like Age or Race , would be level three headings. This pattern continues down to level five headings.

• Age (level three)
• Race (level three)

Styling the Different Headings

Each level has specific formatting requirements to make it visibly obvious which level it is. As with all other text in an APA formatted paper, the font size should be 12pt. The differences between each level are as follows:

Level One Heading

Level one headings are centered and bolded, with all major words capitalized (articles and conjunctions are not captalized).

Level Two Heading

Level two headings are similar to level one headings, except are aligned on the left.

Level Three Heading. Level three headings are similar to levels one and two, except they're indented by 5 spaces, followed by a period, and the text following the heading does not start on a new line.

Level Four Heading. The level four heading is identical to level three, except it is also italicized.

Level Five Heading. Finally, the level five heading is identical to level four, except it is no longer bold.

• Comprehensive Guide to Headings and Subheadings in APA 7.0

Section 1: Introduction to Headings and Subheadings in APA 7.0-

In academic writing, the use of headings and subheadings is crucial for organizing and structuring a paper. APA (American Psychological Association) style, specifically in its 7th edition, provides clear guidelines on how to effectively use headings and subheadings to enhance readability and comprehensibility of research papers, essays, and other scholarly works. This section will provide a comprehensive introduction to the importance, purpose, and benefits of using headings and subheadings in APA 7.0 format.

Purpose of Headings and Subheadings

Headings and subheadings serve as visual cues to help readers navigate through the content of a paper. They create a hierarchical structure, indicating the relationships between different sections and subsections, and aid in organizing ideas and presenting information in a logical manner. By using headings and subheadings, writers can effectively divide their work into manageable and coherent sections, making it easier for readers to comprehend and follow the main arguments and supporting details.

Importance of Headings and Subheadings

Clear and well-structured headings and subheadings are essential in academic writing for several reasons. First and foremost, they enhance the overall readability of the paper by breaking down the text into smaller, digestible chunks. This organization allows readers to quickly identify and locate specific information, especially when they are scanning or skimming through the document.

Secondly, headings and subheadings contribute to the coherence and flow of the paper. By providing a clear roadmap, they guide the reader through the main ideas, supporting evidence, and key points presented in each section. This not only improves the overall structure of the paper but also helps maintain the logical progression of thoughts and arguments.

Additionally, headings and subheadings assist both readers and writers in comprehending complex topics. They enable writers to organize their thoughts, ensuring that each section focuses on a specific aspect or theme. This organization facilitates a deeper understanding of the subject matter for both the writer during the drafting process and the reader during the consumption of the paper.

Formatting Guidelines for Headings and Subheadings

APA 7.0 provides specific rules and formatting guidelines for using headings and subheadings. These guidelines include the use of different levels of headings, capitalization rules, and placement within the paper. Understanding and adhering to these guidelines is crucial for maintaining consistency and conformity with APA style.

The APA 7.0 formatting guidelines for headings and subheadings are based on a five-level hierarchy, with each level indicating the level of importance and hierarchy of information. Level 1 headings are the highest level, followed by Level 2, Level 3, and so on. Each level has a specific formatting style, such as font size, boldness, and indentation, to differentiate it from the other levels. Furthermore, APA 7.0 also provides guidance on the appropriate use of sentence case, title case, and capitalization in headings and subheadings. For instance, Level 1 headings are typically written in sentence case and are centered and bolded. Level 2 headings are aligned to the left margin, bolded, and written in title case. To maintain clarity and consistency, APA 7.0 also provides recommendations on the number of headings to use within a paper. It suggests that at least two headings should be used in any given section, as a single heading alone may not adequately represent the content covered.

Section 2: The Purpose and Importance of Headings and Subheadings in APA 7.0

Facilitating information retrieval.

One of the primary purposes of headings and subheadings in APA 7.0 is to facilitate information retrieval for readers. When faced with a lengthy document, readers often engage in scanning or skimming techniques to locate specific information or sections of interest. Well-structured headings and subheadings act as signposts, allowing readers to quickly identify the content they are seeking without having to read the entire text. By providing a clear and organized hierarchy, headings guide readers to the main sections of a paper, while subheadings further break down the content into more specific subsections. This hierarchical structure enables readers to navigate the document with ease, locating relevant information efficiently. Thus, headings and subheadings in APA 7.0 contribute significantly to the overall accessibility and user-friendliness of academic papers.

Enhancing Readability and Comprehensibility

Headings and subheadings play a vital role in enhancing the readability and comprehensibility of academic writing. They help break up large blocks of text into smaller, digestible sections, preventing the overwhelming feeling that dense paragraphs can create. By visually separating different sections and subsections, headings and subheadings allow readers to mentally prepare for the content they are about to encounter. Additionally, headings and subheadings improve the flow and coherence of a paper. They provide a roadmap for readers, helping them understand the organization and structure of the author's arguments and supporting evidence. Well-crafted headings and subheadings enable readers to follow the logical progression of ideas and maintain a clear understanding of the paper's main points. Finally, headings and subheadings aid in the comprehension of complex topics. By breaking down the content into smaller, focused sections, readers can grasp the material more easily. Headings act as cognitive cues, preparing readers for the information presented in each section. This approach not only facilitates understanding but also allows readers to engage with the content at a deeper level, promoting knowledge retention.

Organizing and Structuring Ideas

Headings and subheadings in APA 7.0 serve as valuable tools for organizing and structuring ideas within a paper. They help writers divide their work into meaningful sections, each addressing a specific aspect or theme related to the overall topic. This organization ensures that information is presented in a coherent and logical manner, making it easier for both the writer and the reader to navigate the paper.

By using headings and subheadings, writers can create a clear outline for their work, ensuring that each section has a distinct focus. This outline acts as a framework, guiding the writer in presenting their arguments and supporting evidence in a systematic and organized way. Writers can use headings to delineate major sections or main ideas, while subheadings allow for further subcategorization and exploration of subtopics.

Furthermore, headings and subheadings assist writers in structuring their thoughts during the writing process. By providing a visual representation of the paper's organization, headings help writers maintain a coherent flow of ideas and prevent the inclusion of irrelevant or tangential information. This structured approach not only improves the overall quality of the paper but also enhances the writer's ability to communicate their ideas effectively.

Conveying the Hierarchical Relationship of Information

Another important purpose of headings and subheadings in APA 7.0 is to convey the hierarchical relationship of information. By assigning different levels to headings, the writer can indicate the relative importance and order of ideas within the paper. Higher-level headings represent broader themes or major sections, while lower-level headings address more specific subtopics or subsections. This hierarchical structure helps readers understand the organization and logical flow of the paper at a glance. It allows them to grasp the overall structure and the relationships between different sections without having to read the entire document. Additionally, the use of indentation and formatting styles for each level of heading further reinforces the hierarchical relationship and aids in visual differentiation.

Section 3: Formatting Guidelines for Headings and Subheadings in APA 7.0

Proper formatting of headings and subheadings is crucial in APA 7.0 style to ensure consistency, clarity, and readability in academic writing. This section will delve into the specific formatting guidelines provided by APA 7.0 for headings and subheadings, including the use of different levels, capitalization rules, and placement within the paper.

Levels of Headings

APA 7.0 introduces a five-level hierarchy for headings, each denoting a different level of importance and significance within the paper. These levels provide a structured framework for organizing the content and help readers understand the organization and flow of ideas. Here are the five headings in APA 7.0:

Level 1: Centered, Bold and Title Case

            Text begins here.

Level 2: Left-Aligned, Bold and Title Case

Level 3: Left-Aligned, Bold, Italics, and Title Case

Level 4: Left-Aligned, Bold, Title Case, and Period. Text begins here.

Level 5: Left-Aligned, Bold, Title Case, Italics, and Period . Text begins here.

Section 4: Organizing and Structuring Your Paper

Using headings and subheadings in apa 7.0.

Organizing and structuring your paper effectively is crucial for presenting your ideas in a logical and coherent manner. Headings and subheadings in APA 7.0 play a vital role in achieving this goal by providing a clear framework for organizing your content. This section will delve into strategies and best practices for utilizing headings and subheadings to organize and structure your paper in accordance with APA 7.0 guidelines.

Preparing an Outline

Before you begin writing your paper, it is helpful to create an outline that outlines the main sections and subsections you intend to cover. An outline acts as a roadmap, allowing you to visualize the overall structure and flow of your paper. It serves as a foundation for developing meaningful headings and subheadings that accurately represent the content and facilitate logical organization. Start by identifying the major sections that your paper will include, such as introduction, literature review, methods, results, discussion, and conclusion. These major sections will serve as Level 1 headings in APA 7.0. Next, break down each major section into subsections that address specific subtopics or aspects related to the main theme. These subsections will be represented by Level 2 headings. Depending on the complexity and depth of your paper, you may further divide the subsections into sub-subsections using Level 3, Level 4, and Level 5 headings. Creating a comprehensive outline not only helps you organize your thoughts but also ensures that you cover all the necessary components of your paper. It allows you to see the relationships between different sections and subsections, enabling you to present your arguments and evidence in a logical and coherent sequence.

Maintaining Consistency and Parallelism

Consistency is key when it comes to organizing and structuring your paper using headings and subheadings. It is important to establish a consistent framework that is followed throughout the entire document. Consistency ensures that readers can easily understand the hierarchy and relationships between different sections and subsections. When creating headings and subheadings, aim for parallelism in terms of grammatical structure and formatting. Parallelism means that headings at the same level should have a similar grammatical structure and formatting style. For instance, if you choose to use noun phrases for Level 2 headings, maintain this pattern consistently across all Level 2 headings in your paper. This helps readers navigate through the content smoothly and maintain a sense of coherence. Furthermore, parallelism extends to the use of punctuation and capitalization within headings and subheadings. Maintain consistent capitalization rules, such as sentence case for Level 1 headings and title case for Level 2 headings. This uniformity enhances the visual hierarchy and clarity of your paper.

Balancing Depth and Granularity

Effective organization and structuring involve finding the right balance between depth and granularity in your headings and subheadings. Level 1 headings represent major sections and should encapsulate broad themes or concepts, providing an overview of what will be discussed within each section. Level 2 headings, as subsections, delve into more specific topics or aspects related to the main theme of the major section.

Reviewing and Revising the Organization

Organizing and structuring your paper using headings and subheadings is not a one-time task. It is an iterative process that requires regular review and revision to ensure optimal clarity and coherence. Once you have completed the initial draft of your paper, review the organization of your headings and subheadings. Ask yourself if the structure effectively reflects the flow of your ideas and supports your main argument. Consider whether the headings accurately represent the content of each section and subsection. During the review process, pay attention to transitions between sections and subsections. Ensure that the headings and subheadings create a smooth transition from one topic to another, guiding readers through the logical progression of your paper. If you notice any gaps or inconsistencies, revise and refine the organization accordingly. Additionally, seek feedback from peers, mentors, or instructors. Their fresh perspective can provide valuable insights into the clarity and effectiveness of your headings and subheadings. Incorporate their feedback and make necessary adjustments to improve the overall organization and structure of your paper.

Section 5: Common Mistakes to Avoid in Using Headings and Subheadings in APA 7.0

While using headings and subheadings in APA 7.0 can greatly improve the organization and readability of your paper, it's important to be aware of common mistakes that can compromise the effectiveness of your headings. By understanding and avoiding these mistakes, you can ensure that your headings enhance the clarity and coherence of your academic writing. This section will explore some common mistakes to avoid when using headings and subheadings in APA 7.0.

Inconsistent Formatting

One of the most common mistakes is inconsistent formatting of headings and subheadings. In APA 7.0, it is crucial to maintain consistency in capitalization, alignment, and formatting styles across headings at the same level. Inconsistencies can confuse readers and disrupt the visual hierarchy of your paper. Ensure that all Level 1 headings have the same formatting, all Level 2 headings have the same formatting, and so on. Consistency in formatting contributes to the overall professionalism and readability of your work.

Poor Alignment and Spacing

Another mistake to avoid is incorrect alignment and spacing of headings and subheadings. In APA 7.0, Level 1 headings are centered and typically start on a new page or a new line with an extra line space before and after the heading. Level 2 headings and lower-level headings, however, are left-aligned and generally require an extra line space before the heading but not after. Failure to align and space headings correctly can create confusion and disrupt the logical flow of your paper. Review APA 7.0 guidelines carefully to ensure proper alignment and spacing of your headings.

Lack of Parallelism

Parallelism, or consistent grammatical structure, is crucial when using headings and subheadings. Headings at the same level should follow a similar structure to maintain coherence and readability. For example, if you use noun phrases for Level 2 headings, ensure that all Level 2 headings follow this pattern. Lack of parallelism can make your headings appear disjointed and may confuse readers. Consistently apply parallel structure within each level of headings to create a smooth and organized flow of information.

Overcomplicating the Heading Structure

While it is important to provide a clear and hierarchical structure to your paper, overcomplicating the heading structure can lead to confusion and excessive fragmentation. Strive to find a balance between providing enough detail to cover your content effectively and avoiding an excessive number of headings and subheadings. Each heading should represent a meaningful subdivision and contribute to the overall organization and coherence of your paper. Aim for a clear and concise heading structure that guides readers without overwhelming them with excessive levels or overly specific subdivisions.

Lack of Descriptiveness

Headings and subheadings should be descriptive and informative to accurately represent the content covered within each section. Avoid using generic or ambiguous headings that do not provide a clear indication of what readers can expect to find. Vague headings can leave readers uncertain about the content or make it challenging to locate specific information within your paper. Ensure that your headings succinctly capture the main ideas or themes of each section, guiding readers through your content effectively.

Ignoring the Reader's Perspective

When creating headings and subheadings, it's important to consider the perspective of your readers. Put yourself in their shoes and think about how your headings will facilitate their understanding and navigation through your paper. Consider whether your headings effectively communicate the main points, guide readers through the logical flow of your arguments, and enable them to locate specific information easily. Ignoring the reader's perspective can result in headings that are unclear, unhelpful, or inconsistent, hindering the overall readability and comprehension of your work.

Neglecting to Revise and Edit Headings

Headings should not be an afterthought or treated as static elements in your paper. Neglecting to revise and edit your headings can lead to inaccuracies, lack of clarity, or poor alignment with the final content of your paper. As you progress through the writing process, continuously review and refine your headings to ensure they accurately represent the content and flow of your arguments. Make necessary adjustments, reword headings for better clarity, and ensure that they align with the finalized structure and organization of your paper.

• using subheadings only when the paper has at least two subsections within a larger section

APA headings and subheadings refers to the rules for formatting sections of documents in the 7th Edition of the American Psychological Association’s Publication Manual .

A research paper written in APA style should be organized into sections and subsections using the five levels of APA headings. 

Related Concepts:

Notice how sections contain at least two smaller subsections in the example below:

Design  

Participants. , demographics..

Characteristics.

Limitations

Starting with the first level of heading, the subsections of the paper should progressively use the next level(s) of heading without skipping any levels. Major sections of the paper’s main body, including the Method, Results, and Discussion sections, should always be formatted with the first level of heading. However, keep in mind that the Introduction section, which is preceded by the full title of the paper, should be presented in plain type. Any subsections that fall under the major sections are formatted with the next level of heading.

Note that all paragraphs of the main body, including those that fall under subsections of a larger section, still maintain the pattern of indentation, use Times New Roman font, 12 pt., and are double-spaced. There are no extra lines or spaces between paragraphs and headings.

How are the five levels of APA-style headings formatted?

Format each of the five levels of APA-style headings as demonstrated in the example below. Note that while the example features headings titled “First Level,” “Second Level,” and so on, each heading in your paper should be named according to the section it describes. 

First level

The first level of heading is bolded and centered, and the first letter of each word in the heading is capitalized. The paragraph text should be typed on the following line and indented five spaces from the left.

Second level

The second level of heading is bolded and situated flush left, and the first letter of each word in the heading is capitalized. The paragraph text should be typed on the following line and indented five spaces from the left.

Third level

The third level of heading is bolded, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Fourth level

The fourth level of heading is bolded, italicized, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Fifth level

The fifth level of heading is italicized, indented five spaces from the left, and followed by a period. Capitalize only the first letter of the first word in the heading and of proper nouns. The first paragraph following this heading should be typed on the same line as the heading.

Method  (1st level)

Design (2nd level)

        Participants (3rd level)

        Demographics. (4th level)

              Age Group. (5th level)

Limitations  (2nd level)

• For student papers, include only the page number in the top right margin of every page of the paper
• For professional papers, place the page number in the top right margin and the running head in the top left margin of every page of the paper. Running heads should be a shortened version of the paper title.

How the brain is flexible enough for a complex world (without being thrown into chaos)

Many neurons exhibit “mixed selectivity,” meaning they can integrate multiple inputs and participate in multiple computations. Mechanisms such as oscillations and neuromodulators recruit their participation and tune them to focus on the relevant information.

Every day our brains strive to optimize a trade-off: With lots of things happening around us even as we also harbor many internal drives and memories, somehow our thoughts must be flexible yet focused enough to guide everything we have to do. In a new paper in Neuron, a team of neuroscientists describes how the brain achieves the cognitive capacity to incorporate all the information that’s relevant without becoming overwhelmed by what’s not.

The authors argue that the flexibility arises from a key property observed in many neurons: “mixed selectivity.” While many neuroscientists used to think each cell had just one dedicated function, more recent evidence has shown that many neurons can instead participate in a variety of computational ensembles, each working in parallel. In other words, when a rabbit considers nibbling on some lettuce in a garden, a single neuron might be involved in not only assessing how hungry it feels but also whether it can hear a hawk overhead or smell a coyote in the trees and how far away the lettuce is.

The brain does not multitask, said paper co-author Earl K. Miller , Picower Professor in The Picower Institute for Learning and Memory at MIT and a pioneer of the mixed selectivity idea, but many cells do have the capacity to be roped into multiple computational efforts (essentially “thoughts”). In the new paper the authors describe specific mechanisms the brain employs to recruit neurons into different computations and to ensure that those neurons represent the right number of dimensions of a complex task.

“These neurons wear multiple hats,” Miller said. “With mixed selectivity you can have a representational space that’s as complex as it needs to be and no more complex. That’s what flexible cognition is all about.”

Co-author Kay Tye , Professor at The Salk Institute and the University of California at San Diego, said mixed selectivity among neurons particularly in the medial prefrontal cortex is key to enabling many mental abilities.

"The mPFC is like a hum of whispers that represents so much information through highly flexible and dynamic ensembles," Tye said. “Mixed selectivity is the property that endows us with our flexibility, cognitive capacity, and ability to be creative.  It is the secret to maximizing computational power which is essentially the underpinnings of intelligence."

Origins of an idea

The idea of mixed selectivity germinated in 2000 when Miller and colleague John Duncan defended a surprising result from a study of cognition in Miller’s lab. As animals sorted images into categories, about 30 percent of the neurons in the prefrontal cortex of the brain seemed to be involved. Skeptics who believed that every neuron had a dedicated function scoffed that the brain would devote so many cells to just one task. Miller and Duncan’s answer was that perhaps cells had the flexibility to be involved in many computations. The ability to serve on one cerebral task force, as it were, did not preclude them from being able to serve many others.

But what benefit does mixed selectivity convey? In 2013 Miller teamed up with two co-authors of the new paper, Mattia Rigotti of IBM Research and Stefano Fusi of Columbia University, to show how mixed selectivity endows the brain with powerful computational flexibility. Essentially, an ensemble of neurons with mixed selectivity can accommodate many more dimensions of information about a task than a population of neurons with invariant functions.

“Since our original work, we've made progress understanding the theory of mixed selectivity through the lens of classical machine learning ideas,” Rigotti said. “On the other hand, questions dear to experimentalists about the mechanisms implementing it at a cellular level had been comparatively under-explored. This collaboration and this new paper set out to fill that gap.”

In the new paper the authors imagine a mouse who is considering whether to eat a berry. It might smell delicious (that’s one dimension). It might be poisonous (that’s another). Yet another dimension or two of the problem could come in the form of a social cue. If the mouse smells the berry scent on a fellow mouse’s breath, then the berry is probably OK to eat (depending on the apparent health of the fellow mouse). A neural ensemble with mixed selectivity would be able to integrate all that.

Recruiting neurons

While mixed selectivity has the backing of copious evidence—it has been observed across the cortex and in other brain areas such as the hippocampus and amygdala—there are still open questions. For instance, how are neurons recruited to tasks and how do neurons that are so “open-minded” remain tuned only to what really matters to the mission?

In the new study, the researchers who also include Marcus Benna of UC San Diego and Felix Taschbach of The Salk Institute, define the forms of mixed selectivity that researchers have observed, and argue that when oscillations (also known as “brain waves”) and neuromodulators (chemicals such as serotonin or dopamine that influence neural function) recruit neurons into computational ensembles, they also help them “gate” what’s important for that purpose.

To be sure, some neurons are dedicated to a specific input, but the authors note they are an exception rather than the rule. The authors say these cells have “pure selectivity.” They only care if the rabbit sees lettuce. Some neurons exhibit “linear mixed selectivity,” which means their response predictably depends on multiple inputs adding up (the rabbit sees lettuce and feels hungry). The neurons that add the most dimensional flexibility are the “nonlinear mixed selectivity” ones that can account for multiple independent variables without necessarily summing them. Instead they might weigh a whole set of independent conditions (e.g. there’s lettuce, I’m hungry, I hear no hawks, I smell no coyotes, but the lettuce is far and I see a pretty sturdy fence).

So what brings neurons into the fold to focus on the salient factors, however many there are? One mechanism is oscillations, which are produced in the brain when many neurons all maintain their electrical activity at the same rhythm. This coordinated activity enables information sharing, essentially tuning them together like a bunch of cars all playing the same radio station (maybe the broadcast is about a hawk circling overhead). Another mechanism the authors highlight is neuromodulators. These are chemicals that upon reaching receptors within cells can influence their activity as well. A burst of acetylcholine, for instance, might similarly attune neurons with the right receptors to certain activity or information (like maybe that feeling of hunger).

“These two mechanisms likely work together to dynamically form functional networks,” the authors write.

Understanding mixed selectivity, they continue, is critical to understanding cognition.

“Mixed selectivity is ubiquitous,” they conclude. “It is present across species and across functions from high-level cognition to ‘automatic’ sensorimotor processes such as object recognition. The widespread presence of mixed selectivity underscores its fundamental role in providing the brain with the scalable processing power needed for complex thought and action.”

How to Create a Table of Contents in Word for Your Paper? [For Students]

Working on a paper or thesis is mentally exhausting on its own, but having to format everything according to MLA, APA, or Chicago style can be a real headache, especially when creating a table of contents. Manually updating it every time you make changes is tedious and error-prone. What you really need is a way to generate and update the table of contents automatically, allowing you to concentrate on the content without worrying about the structure.

This makes the entire process smoother and less stressful, letting you focus on your research without the constant formatting frustration. In this article, we will explore the essentials of creating a functional and clear table of contents Word for students, covering what it is, why it's important, and how to prepare one that effectively outlines your paper's structure.

Table of Contents in APA, MLA and Chicago Style

In academic writing, particularly for longer pieces such as thesis, dissertations, and research papers, having a clear organization is highly beneficial. A crucial aspect that helps readers navigate your work is a Table of Contents (TOC). Despite the variations in specific style guides like APA, MLA, or Chicago, incorporating a TOC provides numerous advantages. Besides these benefits, TOCs in these three academic formats adhere to generally similar guidelines, although there are some differences that must be acknowledged and addressed.

1. A Table of Contents in APA

The American Psychological Association (APA) style is commonly used in the social sciences. While APA style does not always require a table of contents, it is often recommended for lengthy papers or theses. Here's how to structure a table of contents in APA style:

Placement : The TOC goes between the abstract and introduction on a separate page.

Formatting : Use the same font and size as your main text (typically 12 pt Times New Roman).

Title : Center and bold the word "Contents" at the top of the page.

Heading Levels : Include all level 1 (main sections) and level 2 (subheadings) headings in the TOC.

Alignment : Left-align all entries in the TOC.

Indentation : Level 2 headings are indented for clarity.

Lower Levels (Optional) : Including level 3 headings or lower is optional and requires additional indentation for each level.

Length : Keep the TOC concise; ideally, it shouldn't exceed two pages.

2. A Table of Contents in MLA

The Modern Language Association (MLA) style is typically used in the humanities. While MLA does not always require a table of contents for shorter papers, longer academic works may benefit from having one. Here are some tips for creating a table of contents in MLA style:

Font and Size : Stick to Times New Roman, 12 point size, for consistency with the rest of your document.

Margins : Use standard 1-inch margins on all sides.

Spacing : Double line spacing is the norm for MLA formatting.

Indentations : Create a clear distinction between paragraphs with a ½-inch indent for the first line.

Headings : Use title case capitalization (capitalize the first word of each main word) for your headings in the TOC.

3. A Table of Contents in Chicago Style

The Chicago Manual of Style (CMS) is widely used in historical and other academic research. Chicago style often requires a detailed table of contents for dissertations and other extensive works. Here's how to create a table of contents in Chicago style:

Starting Fresh : Begin your TOC on a separate page following the title page.

Clear Labeling : Center the title "Contents" at the top of the page.

Spacing for Readability : Leave a double space between "Contents" and the first entry in your TOC.

Mirroring Your Paper : List chapter titles, headings, and subheadings in the exact order they appear in your paper.

Matching Matters : Ensure capitalization and the hierarchy of titles/headings in the TOC match your paper's formatting.

Pinpointing Locations :  Place page numbers flush right, using leader dots (a series of periods) to connect them to the corresponding entry.

How to Create a Table of Contents Easily in Word for Your Paper

Before inserting a table of contents in Word , we first need to format the headings of our research paper or thesis according to an academic style.

Let's take a look at it through an example for better understanding. We need to write a research paper on Environment Safety, so before getting started with the writing part, let’s create an outline for it. This means we will need to lay out the headings in order. We have a main heading called Heading 1, and then we have subheadings called Heading 2. In some instances, we have Heading 3 or Heading 4 as well, so let's take a look at the breakdown of these headings beforehand.

H1 : The main heading of your document, typically used once for the overall title.

H2 : Subheadings that break down your H1 topic into major sections.

H3 : Subheadings that further divide your H2 sections into more specific points.

If you understand this, then formatting will be a breeze for you. So let's jump right into it:

Step 1 : We now have our outline laid out in our document on Microsoft Word.

Step 2 : Even though I went through and formatted my headings and subheadings by increasing the font size of the main headings and making them bold, this is completely wrong.

Step 3 : In Word, we need to do proper formatting. To do this, click on your main heading of the essay and head over to the Home tab.

Step 4 : Now, in the "Styles" section, you will see various styles. From this, click on "Heading 1", and you will notice a change in your headings formatting.

Step 5 : To change the formatting to fit your academic style, right-click on the "Heading 1" button in the Styles section to open the context menu, and then click on "Modify".

Step 6 : In the Modify Style dialog, users can change the font, font size, and other changes to format their heading.

Step 7 : Similarly, click on Heading 2 in your document, then in the Styles section, select Heading 2, and so on.

Step 8 : Once all the headings have been formatted, now we can proceed to inserting a table of contents into our document.

Step 9 : To insert the table of contents, visit the Reference tab and then click on the "Table of Contents" option in the ribbon menu.

Step 10 : Microsoft Word gives its users the option to insert a pre-formatted table of contents, but if you wish to insert a custom-made table of contents, that's also possible.

Step 11 : Once you have selected your desired table of contents, it will be added, and you can now complete your work with ease.

How to Update the Table of Contents in Word for Your Paper

The outline was ready, or at least that's what we thought, but now we added a few new headings, but they won't show up in the table of contents. Now, to address this, we need to Update our Table of Contents:

Step 1 : Let's open Microsoft Word again. As we can see, there's nothing changed in the table of contents even though we've correctly styled the headings in our essay.

Step 2 : To update the table of contents, right-click anywhere on the table of contents to open the context menu.

Step 3 : In the context menu, we need to click on "Update Field" or simply press the shortcut key "F9".

Step 4 : Now, we see the Update Table of Contents dialog. Click on "Update entire table" and then click "OK".

Step 5 : The table of contents will now be completely updated with the new headings that you've inserted.

Bonus Tip: Converting Your Paper to PDF Without Losing Format

Once you're done with your paper and a well-organized table of contents, the next step is often converting it to a PDF. This is crucial because PDFs preserve formatting, ensuring that your hard work doesn't get scrambled when shared or printed. However, conversion can be tricky, especially with Microsoft Word 365. When converting a document to PDF in Word 365, you might encounter issues like misaligned text, broken page breaks, or distorted table of contents formatting.

WPS Office is an excellent alternative to Microsoft Word 365 for PDF conversions. It offers robust PDF features that can convert your paper without losing formatting. Here's why WPS Office might be a better choice:

Direct PDF Conversion : WPS Office has a built-in PDF converter that maintains the layout and structure of your document, reducing the risk of misalignment.

Enhanced PDF Features : WPS Office allows you to merge, split, or compress PDFs , which can be useful if you need to adjust your document after conversion.

Easy Table of Contents Management : WPS Office handles tables of contents well, ensuring links and formatting remain intact.

WPS Office: Use Word, Excel, and PPT for FREE, No Ads.

Now, to convert your Word document with the table of contents into a PDF document without losing any formatting in the process, WPS Office provides a very easy and effective solution:

Step 1 : Let's open the Word document in WPS Office and then head over to the Menu on the top left of the page.

Step 2 : In the menu, click on "Save as" and select "Other formats" from the flyout menu.

Step 3 : Simply in the Save as options, change the file type to "PDF" in the "File Type" field and then hit "Save" to save your document as a PDF.

FAQs about Table of Contents in Word

Solar Storm Intensifies, Filling Skies With Northern Lights

Officials warned of potential blackouts or interference with navigation and communication systems this weekend, as well as auroras as far south as Southern California or Texas.

By Katrina Miller and Judson Jones

Katrina Miller reports on space and astronomy and Judson Jones is a meteorologist.

A dramatic blast from the sun set off the highest-level geomagnetic storm in Earth’s atmosphere on Friday that is expected to make the northern lights visible as far south as Florida and Southern California and could interfere with power grids, communications and navigations system.

It is the strongest such storm to reach Earth since Halloween of 2003. That one was strong enough to create power outages in Sweden and damage transformers in South Africa.

The effects could continue through the weekend as a steady stream of emissions from the sun continues to bombard the planet’s magnetic field.

The solar activity is so powerful that the National Oceanic and Atmospheric Administration, which monitors space weather, issued an unusual storm watch for the first time in 19 years, which was then upgraded to a warning. The agency began observing outbursts on the sun’s surface on Wednesday, with at least five heading in the direction of Earth.

“What we’re expecting over the next couple of days should be more significant than what we’ve seen certainly so far,” Mike Bettwy, the operations chief at NOAA’s Space Weather Prediction Center, said at a news conference on Friday morning.

For people in many places, the most visible part of the storm will be the northern lights, known also as auroras. But authorities and companies will also be on the lookout for the event’s effects on infrastructure, like global positioning systems, radio communications and even electrical power.

While the northern lights are most often seen in higher latitudes closer to the North Pole, people in many more parts of the world are already getting a show this weekend that could last through the early part of next week.

As Friday turned to Saturday in Europe, people across the continent described skies hued in a mottling of colors.

Alfredo Carpineti , an astrophysicist, journalist and author in North London, saw them with his husband from the rooftop of their apartment building.

“It is incredible to be able to see the aurora directly from one’s own backyard,” he said. “I was hoping to maybe catch a glimpse of green on the horizon, but it was all across the sky in both green and purple.”

Here’s what you need to know about this weekend’s solar event.

How will the storm affect people on Earth?

A geomagnetic storm watch or warning indicates that space weather may affect critical infrastructure on or orbiting near Earth. It may introduce additional current into systems, which could damage pipelines, railroad tracks and power lines.

According to Joe Llama, an astronomer at Lowell Observatory, communications that rely on high frequency radio waves, such as ham radio and commercial aviation , are most likely to suffer. That means it is unlikely that your cellphone or car radio, which depend on much higher frequency radio waves, will conk out.

Still, it is possible for blackouts to occur. As with any power outage, you can prepare by keeping your devices charged and having access to backup batteries, generators and radio.

The most notable solar storm recorded in history occurred in 1859. Known as the Carrington Event, it lasted for nearly a week, creating aurora that stretched down to Hawaii and Central America and impacting hundreds of thousands of miles of telegraph lines.

But that was technology of the 19th century, used before scientists fully understood how solar activity disrupted Earth’s atmosphere and communication systems.

“That was an extreme level event,” said Shawn Dahl, a forecaster at NOAA’s Space Weather Prediction Center. “We are not anticipating that.”

Unlike tornado watches and warnings, the target audience for NOAA’s announcements is not the public.

“For most people here on planet Earth, they won’t have to do anything,” said Rob Steenburgh, a space scientist at NOAA’s Space Weather Prediction Center.

The goal of the announcements is to give agencies and companies that operate this infrastructure time to put protection measures in place to mitigate any effects.

“If everything is working like it should, the grid will be stable and they’ll be able to go about their daily lives,” Mr. Steenburgh said.

Will I be able to see the northern lights?

It is possible that the northern lights may grace the skies this week over places that don’t usually see them. The best visibility is outside the bright lights of cities.

Clouds or stormy weather could pose a problem in some places. But if the skies are clear, even well south of where the aurora is forecast to take place, snap a picture or record a video with your cellphone. The sensor on the camera is more sensitive to the wavelengths produced by the aurora and may produce an image you can’t see with the naked eye.

Another opportunity could be viewing sunspots during the daytime, if your skies are clear. As always, do not look directly at the sun without protection. But if you still have your eclipse glasses lying around from the April 8 event, you may try to use them to try to spot the cluster of sunspots causing the activity.

How strong is the current geomagnetic storm?

Giant explosions on the surface of the sun, known as coronal mass ejections, send streams of energetic particles into space. But the sun is large, and such outbursts may not cross our planet as it travels around the star. But when these particles create a disturbance in Earth’s magnetic field, it is known as a geomagnetic storm.

NOAA classifies these storms on a “G” scale of 1 to 5, with G1 being minor and G5 being extreme. The most extreme storms can cause widespread blackouts and damage to infrastructure on Earth. Satellites may also have trouble orienting themselves or sending or receiving information during these events.

The current storm is classified as G5, or “extreme.” It is caused by a cluster of sunspots — dark, cool regions on the solar surface — that is about 16 times the diameter of Earth. The cluster is flaring and ejecting material every six to 12 hours.

“We anticipate that we’re going to get one shock after another through the weekend,” said Brent Gordon, chief of the space weather services branch at NOAA’s Space Weather Prediction Center.

Why is this happening now?

The sun’s activity ebbs and flows on an 11-year cycle, and right now, it is approaching a solar maximum. Three other severe geomagnetic storms have been observed so far in the current activity cycle, which began in December 2019, but none were predicted to cause effects strong enough on Earth to warrant a watch or warning announcement.

The cluster of sunspots generating the current storm is the largest seen in this solar cycle, NOAA officials said. They added that the activity in this cycle has outperformed initial predictions .

More flares and expulsions from this cluster are expected, but because of the sun’s rotation the cluster will be oriented in a position less likely to affect Earth. In the coming weeks, the sunspots may appear again on the left side of the sun, but it is difficult for scientists to predict whether this will cause another bout of activity.

“Usually, these don’t come around packing as much of a punch as they did originally,” Mr. Dahl said. “But time will tell on that.”

Jonathan O’Callaghan contributed reporting from London.
