| Research Abstract |
To test the hypothesis that prosocial behavior requires the concurrent development of empathy and mentalizing, we applied behavioral analysis and functional MRI to normal, disease and different cultural groups to clarify the neural basis of a self-other similarity and distinction, and the relationship between empathy and mentalizing in driving prosocial behavior. Our infant behavioral and adult fMRI studies indicate that the ability to predict others' action goals requires a corresponding motor ability, providing evidence for a direct matching process by a mirror neuron system. The simultaneous fMRI in pairs of adults showed that the inter-subjectivity is represented by the neural synchronization of the mirror neuron system. Finally our fMRI studies confirmed that the prosocial behaviors are driven by social acceptance through mentalizing, as well as warm glow through empathy, both of which are involved in the reward system, shedding lights on the mechanism of prosocial behavior.
