Formatting section titles in boldface type is one of the main ways to differentiate between important sections in an APA style research paper. While bold formatting for titles is not explicitly required in the APA Publication Manual (7th edition), it is one of the most common stylistic elements used to visually stand out section headings from normal text in papers written for psychology and other social sciences courses that utilize APA style.
The general logic behind bolding section titles is that it allows readers to quickly scan a document and identify the major topic or area being covered in each new section at a glance. With bolded headings, the manuscript flow and organization are easier for readers to follow without having to stop and carefully read every heading word-for-word. Bold formatting creates a typographical hierarchy that helps maintain order and coherence throughout longer papers with multiple nested subsections.
When determining which sections require boldface formatting in an APA style paper, all primary section titles such as the Introduction, Method, Results, and Discussion should always be bolded. Headings for any other expressly numbered or labeled main sections like References or Appendices are also bolded. Secondary subsection titles do not necessarily need bold formatting. The APA Manual does not provide explicit guidance on the formatting of nested subsection titles, leaving some discretion to individual writers and journal style preferences.
As a general rule, most APA papers will bold only primary level 1 headings for the major paper sections. Subsection headings at level 2 or deeper are usually not bolded and instead rely on typographical cues like underlining, italics, capitalization styles, or numbered/lettered formatting to effectively designate heading hierarchy on the page. This makes the body of the paper easier to parse visually while still distinguishing main section breaks.
It is also common practice in some disciplines to bold higher order subsection titles in addition to main headings, such as bolding level 1 and level 2 headings while leaving level 3+ non-bolded. Manuscript length and complexity are factors to consider, as bolded deep subheadings may become overkill in longer papers with many nested levels. Authors also need to maintain consistency – either bolding all subsection title levels or none beyond the primary headings for logical flow and formatting uniformity.
Regardless of which section titles receive bold formatting treatment, the actual formatting process is straightforward in Word. To bold a title, simply select the heading text and click the bold button or use the keyboard shortcut Ctrl+B (Windows) or Command+B (Mac) before beginning the section content below it. An alternative is to apply a Heading style like Heading 1, 2, etc. through the Styles toolbar which will automatically bold primary headings by default.
For cohesion, section titles should be formatted as a complete thought or sentence rather than as a phrase or words. This means including necessary punctuation like periods after declarative title statements. Headings should also start on separate lines from the text below and any other styling like italics, underlines, or capitalization should be consistent with the rest of the document format.
Overall, using boldface for section titles in an APA research paper provides a clean and easy-to-follow typographical hierarchy that helps organize ideas and guide readers through the structure and content flow. By bolding primary section headings and discretionary higher order subsections, authors can better draw attention to crucial transition points while maintaining typographic coherence throughout longer manuscripts.
