How should section and subsection headings be formatted in APA style?
A research paper written in APA style should be organized into sections and subsections using the five levels of APA headings. APA recommends using subheadings only when the paper has at least two subsections within a larger section. Notice how sections contain at least two smaller subsections in the example below:
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.
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.
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.
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.
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.
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.
Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?”, the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.
In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.
This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.
Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).
Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.
Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).
Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.
As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”
Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.
David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).
Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.
Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting”, Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.
Writing at Work
APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:
- MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
- Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
- Associated Press (AP) style. Used by professional journalists.
The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.
The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:
- The name(s) of the author(s) or institution that wrote the source
- The year of publication and, where applicable, the exact date of publication
- The full title of the source
- For books, the city of publication
- For articles or essays, the name of the periodical or book in which the article or essay appears
- For magazine and journal articles, the volume number, issue number, and pages where the article appears
- For sources on the web, the URL where the source is located
The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. (Chapter 13 “APA and MLA Documentation and Formatting”, Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)
In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.
- Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
- Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
- APA papers usually include an abstract that concisely summarizes the paper.
- APA papers use a specific headings structure to provide a clear hierarchy of information.
- In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
- In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.
