ABSTRACT
The role of gender role in interpreting sex differences in emotion is unknown. The present study examined how gender role moderates sex differences in emotional reactivity. Event-related potentials (ERP) were recorded in sixty-eight subjects with typical or androgynous gender roles when they passively observed neutral and negative pictures. Behaviorally, typical females (feminine females) reported higher emotional rating than typical males (masculine males), while androgynous males and androgynous females reported no significant differences. Electrophysiologically, we found higher late positive potential (LPP) amplitude in typical females compared to typical males, while this pattern of sex difference was absent in androgynous subjects. The network analysis of EEG data indicates that typical males showed enhanced network coupling strengths between frontal/prefrontal and parietal areas than typical females, which was again absent in androgynous subjects. These findings suggest that gender role is an important determinant in the interpretation of sex differences in emotional reactivity.
