Question

How do you cite a source with 4 or more authors?

Answer 1

List all the authors in the signal phrase or in parentheses the first time you cite the source.

(Kernis, Cornell, Sun, Berry, & Harlow, 1993)
In subsequent citations, only use the first author's last name followed by "et al." in the signal phrase or in parentheses.

(Kernis et al., 1993)

Answer 2

That applies for any reference with 3-5 authors. For 6 or more authors, use et al. in ALL citations.
