APA Style (7th ed.)
No, because "the first paragraphs of a paper are understood to be introductory" (American Psychological Association, 2020, p. 47). The introduction may include Level 2 section headings to label sub-sections in the introduction because "the paper title at the top of the first page of text acts as a de facto Level 1 heading" (American Psychological Association, 2020, p. 47). At the conclusion of the introduction, begin the next section of the paper with a Level 1 heading.
