| Outline of Final Research Achievements |
High sociality contributes to helping behavior. One of major motives for helping behavior is empathic joy, empathizing with anticipated joy of help recipient. We conducted functional magnetic resonance imaging (fMRI) experiments to investigate neural correlates underlying helping behaviors motivated by empathic joy. As a result, we found activity in reward system (dorsal striatum) during helping behaviors with alleviating aversive arousal response in anterior cingulate cortex. Furthermore, we showed empathic social behavior is perceived as reward and alleviates visual cortex activation in response to aversive stimuli. This result suggested that interrelationship between empathic joy and pain motivates helping behavior and such kind of social behavior is effective for recipients.
