Research ReportSex difference in the processing of task-relevant and task-irrelevant social information: An event-related potential study of familiar face recognition
چکیده انگلیسی

Behavioral studies suggest that men are more likely to develop independent self-construals whereas women are more likely to develop interdependent self-construals. The gender difference in self-construals leads to two predictions. First, independent self-construals may result in a bias of attentional processing of self-related information that is stronger in men than in women. Second, interdependent self-construals may induce greater sensitivity to contextual information from the environment in women than in men. The present study tested these hypotheses by recording event-related potentials (ERPs) to familiar faces (self-, mother-, and father-faces) and unfamiliar faces (gender/age matched strangers' faces) from 14 male and 14 female adults. Using an odd ball paradigm, in separate blocks of trials, familiar faces were designated as either targets that required behavioral responses or as non-targets that did not require a behavioral response. We found that a long latency positivity at 420-620 ms over the parietal area (the attention sensitive target P3) showed a larger amplitude to self-face than to mother-/father-faces that were designated as targets in men but not in women. In contrast, a long latency positivity at 430-530 ms over the central area (the context sensitive novelty P3) was enlarged to familiar compared to strangers' faces that were designated as non-targets and this effect was greater in women than in men. Our results showed ERP evidence for sex differences in the processing of task-relevant and task-irrelevant social information.

► Men scored higher than women in individualism/independent self-construal subscale. ► Target P3 was enlarged to self- than mother-/father-faces in men. ► Novelty P3 was enlarged to familiar than unfamiliar faces in women. ► Sex differences exist in the processing of faces of self and close others.
