Empathic concern induction modulates behavioral ratings and neural responses to harm-related moral judgment: An event-related potentials study.

Although empathic concern is critical in harm-related moral judgment, the temporal dynamics underlying the impact of empathic concern on moral judgment remain unclear. This study used event-related potentials (ERPs) to investigate how empathic concern induction shaped the way individuals perceive harmful/helpful behaviors. Behavioral results showed that participants assigned more blame to harmful behaviors in the empathic concern priming condition compared to those in the control condition. ERP results showed that helpful behaviors elicited larger N1 than did harmful behaviors. Additionally, harmful behaviors in the empathic concern priming condition elicited more negative N2 than did harmful behaviors in the control condition. Moreover, harmful behaviors elicited larger late positive potential (LPP) than did helpful behaviors in the control condition. These findings suggest that (1) empathic concern induction might increase moral sensitivity about harm-related norms; (2) participants independent of the empathic concern manipulation can distinguish between harmful behaviors and helpful behaviors similarly, as indicated by the early ERP component (N1); (3) empathic concern especially influences the intermediate (N2) and later (LPP) ERP components.
