Self-rated social-emotional perception and its neurophysiologic and cardiac correlates while viewing a film showing the suffering of other people

Using electroencephalographic (EEG) and cardiac measures, the study examined relevant mechanisms that may explain individual differences in self-rated emotion perception (i.e., the propensity of perceiving the emotional states of other persons in everyday life). Healthy women (n = 122) were confronted with film scenes showing the suffering of other people. Functional coupling between prefrontal and posterior cortices, measured by EEG coherences, more strongly decreased in individuals higher on emotion perception. This finding suggests that the propensity to loosen prefrontal inhibitory control on posterior cortical areas involved in basic processes of emotion perception is associated with higher susceptibility to social-emotional information and, therefore, with higher scores on self-rated emotion perception. In addition, higher self-rated perception of other persons' emotions was related to more pronounced cardiac responses to the observation of horrifying events occurring to people in the film which indicate enhanced attention and heightened perceptual processing
