Outline of Final Research Achievements

The study aimed to develop an animal model for studying a reward strategy process based on social interactions. Marmoset monkeys as well as humans were known the only primates showing unsolicited prosociality. We have trained marmosets to choose visual targets on a touch-screen monitor to get a juice reward. Next, we have been developing a behavior recording system of social-related (interindivisual) reward choice task for marmosets in the neighboring cages. The study suggests a possibility that development of an inetrindivisual behavioral task using marmosets can contribute to elucidate the basis of social-related reward strategy process in humans.
