Sex differences in memory for human faces is reviewed. It is found that research evidence to date is not conclusive, but where differences exist they favor female superiority over males in facial memory. In particular, evidence is cited to suggest that females are reliably superior to males in their recognition memory for other females. This is explained in terms of attribution theory and motivational differences between the sexes. The argument is made that theoretical explanations of memory for faces are insufficient if they rely solely on traditional information-processing models without including and accounting for differences in self-awareness. The paper concludes with a description of a recent study on recognition memory of photographs of subjects' own faces in which females prove superior to males in recognizing projections of their real self, their most sociable self, their most intelligent self, and their most trustworthy self.
