In-text citation format
APA uses author–date parenthetical citations. Page numbers are required for direct quotes and recommended when paraphrasing a specific passage.
Paraphrase
Cognitive load increases sharply once decision-making continues past three hours (Tahir & Brennan, 2021).
Direct quote with page number
Tahir and Brennan (2021) describe the threshold as "the point at which clinical reasoning narrows rather than deepens" (p. 224). The ampersand is used inside parentheses; and is spelled out when the names are part of the sentence.
Three or more authors
(Iqbal et al., 2019) - APA 7 uses et al. from the very first citation when there are three or more authors. APA 6 spelled out all authors on the first appearance; the rule changed in the 7th edition and is one of the most common inherited errors.
Multiple works in one parenthesis
Order alphabetically by first author and separate with semicolons: (Brennan, 2020; Park et al., 2022; Tahir & Brennan, 2021). The order is alphabetical, not chronological.
Same author, same year
Distinguish with lowercase letters appended to the year, ordered alphabetically by title in the reference list: (Brennan, 2020a; Brennan, 2020b). The letters appear in both the in-text citation and the reference list.
