Relationship between sex-role identity and functional cerebral lateralization.
The present study examined the relationship between sex-role identity (SRI) and functional cerebral lateralization (FCL) in right-handed males. Two tasks (figure task and location task) were used to assess FCL. The figure task required the identification of shape stimuli, while the location task involved identification of the position of stimuli. SRI was assessed by the Bem Sex Role Inventory (BSRI). Males with higher masculine scores in the BSRI indicated greater differences in the reaction time between right and left visual-fields in the location task. This finding suggests that males with higher masculinity in SRI might have greater FCL.
