Effects of Sexually Dimorphic Shape Cues on Neurophysiological Correlates of Women’s Face Processing

Participants performed a sex categorization task using images varying in sexual dimorphism. Sexual dimorphism modulated superior-central N250 magnitude and N170 and P200 peak latency. The sex of the face further modulated the amplitude of the P200. These findings extend prior work linking the superior-central N250 to social categorization processes.
