To make our results on the body-selective N response directly comparable with prior studies, we presented participants with nude and fully clothed male and female stimuli. Brain responses to different stimuli in Experiment 2. Our ERP data show for the first time that early visual processing of nude over clothed bodies is enhanced. Evol Hum Behav The procedure for the ERP measurements was similar to that in Experiment 1. Cogn Brain Res Figure 2 shows ERPs from two occipito-temporal T5, T6 channels and scalp topographies of the mean voltage amplitudes for different stimulus types averaged across stimulus sex.
Altogether these results show that early face and body sensitive cortical responses are sensitive to the visibility of the sex-related features of human bodies and that the human brain exhibits enhanced visual processing of other people's nude bodies, a mechanism possibly beneficial in identifying potential mating partners and competitors.
