The influence of empathic concern on evaluative processing in self and charity outcomes.

Abstract

Empathy plays a crucial role in determining how one understands others' emotional experiences and behavioral decisions. This study aimed to explore whether empathic concern affects the processing of self-related and charity-related outcome evaluations. In this study, participants performed gambling tasks for themselves and low- and high-empathy charities. The behavioral results showed that low-empathy charities had a significantly higher risk rate than the self, whereas there was no significant difference between low-and high-empathy charities. The event-related potential (ERP) results showed that the P300 valence difference (d-P300) of the self was significantly higher for high-empathy charitable activities than for low-empathy charitable activities, and the d-P300 of high-empathy charitable activities was significantly higher than that of low-empathy charitable activities. The P300 valence differences primarily originated from activation difference in the posterior mid-cingulate cortex (pMCC) and medial prefrontal cortex (mPFC). The time-frequency analysis showed that positive outcomes induced greater β2 event-related desynchronization (ERD) amplitudes for high-empathy charitable activities compared to negative outcomes. These findings suggest that empathic concern increased the distinction between good and bad outcomes for charities and promoted greater cognitive effort allocation toward prosocial rewards. The d-P300 is closely linked to activations in the pMCC and mPFC.
