ABSTRACT
Are boys more aggressive than girls? Although a tremendous amount of research over the last several decades supports an answer of “yes” (Block, 1983; Parke & Slaby, 1983), more recent research would also support an answer of “it depends” (Knight, Guthrie, Page, & Fabes, 2002). That is, it depends on important contextual factors that might vary across investigations such as the definition of aggression, the method of assessment employed, and the age of the child/adolescent.
