| Research Abstract |
Partner choice is one of the most important decision making for social life in primates including human. The aims of this study are to elucidate a strategy of social partner choice to get more rewards and neural systems underlying social partner choice. In human experiment, I compared behavioral strategies between when subjects could choose their partners and when their partners had been pre-determined. The results showed that the subjects showed more cooperative behaviors when they could choose their partners by themselves. In monkey experiment, I recorded neuronal activity from the amygdala while the monkeys were choosing one of the two options which were directed by facial expression of partners. I found the neuron showing different activity in response to different identity of the stimuli. This result indicates that the amygdala is involved in processing of who is the partner.
