Although gender differences in empathy have been well established through measuring subjective outcomes, some studies of the neural mechanisms of pain empathy have not found gender differences. This inconsistent evidence may be caused by different research methods or different paradigms. The present study adopted a different approach from the pain empathy paradigm to examine gender differences in empathic responses to others’ economic payoffs using event-related potentials. The results showed that the N2 amplitudes in female participants were more negative than those in male participants, indicating a greater female than male susceptibility to facial expressions at the early stage of empathy. The LPP amplitudes for male participants were found to be more positive in the observation condition (involving no self-interest) than in the participation condition (involving self-interest), but there was no significant difference in the LPP amplitudes for the female participants between the two conditions. The results suggest that females’ empathic responses are more likely to be elicited automatically by the perception of others’ emotional states. In contrast, males’ empathic responses are more likely to be mediated by self-interest, which subsequently reduces their empathic responses.
