Modulation of behavioral and brain responses to visual perspective taking by social rejection: Evidence from electrophysiology
Abstract
Visual perspective taking (VPT) is crucial for reasoning about other people's mental states. To explore the modulation of behavioral and neural responses to visual perspective taking by social rejection, we firstly manipulated rejection using get-acquainted oral communication and a two-person visual perspective task, then explored how the experience of social rejection affected the behavioral and neural responses during the follow-up classical one-person visual perspective task. The subjective rating and behavior results showed that social rejection increased individuals' negative affect level and feelings of need-threat, decreased self-regulation and impulsive control. The event-related potentials (ERP) and standardized low resolution brain electromagnetic tomography (sLORETA) results mainly showed that the increased parietal late slow wave (LSW) showed greater activities in SPL and rTPJ after social rejection. Moreover, compared with making judgments from self-perspective, making judgments from other-perspective yielded later TP450 and greater late frontal wave (LFW). In addition, the left LFW of socially rejected group showed more positive amplitude for other-inconsistent condition than that for other-consistent condition. These results suggested that social rejection might decrease impulsive control behaviorally, as well as increase neural processing of perspective taking, including visual-spatial perspective taking (indexed by the LSW), calculating of the self and other…
