What should be included on the first line of the abstract page in APA format?

In APA format, the first line of the abstract page should include the word "ABSTRACT." This serves as a clear and standardized heading that indicates the beginning of the abstract section. The abstract provides a concise summary of the research paper's content, including the main purpose, methodology, results, and conclusions. By placing "ABSTRACT" at the top, readers can quickly identify the section that summarizes the entire study, ensuring that they understand the scope of the research at a glance.

The other options do not align with APA guidelines for formatting an abstract. For instance, "SUMMARY" is not used in this context, and including the title of the paper or the author's name would deviate from the specific formatting rules that dictate the structure of an abstract in APA style. The adherence to the term "ABSTRACT" reinforces clarity and uniformity across scholarly works in psychology and other fields that utilize APA format.
