Perceived reputation of others modulates empathic neural responses.

Empathy enables us to understand and share the emotional and affective states of another person and plays a key role in social behaviors. The current study investigated whether and how empathic neural responses to pain were modulated by the perceived reputation of others. Action histories reflecting individuals' past cooperation or betrayal actions in the repeated prisoner's dilemma game were introduced as an index of reputation. We assessed brain activity with functional magnetic resonance imaging while the participants observed individuals with a good or bad reputation receiving or not receiving pain. The results indicated that the participants exhibited reduced empathic responses in AI and dACC to the individual who had a bad reputation relative to the one who had a good reputation, suggesting that their empathy for pain was modulated by the perceived reputation of others.
