| Research Abstract |
Using a series of behavioral experiments and brain-imaging method, we investigated how third parties contribute to achieve sustainable mutual cooperation in large-scale groups. The results of these experiments suggest that 1) people estimate others' cooperativeness using "theory of mind" and make decision whether or not to interact with others, 2) in addition, people's own cooperativeness and/or social anxiety also affects the decision. We also found that people from the third party point of view, has generally negative interpersonal impressions to punishers who contributed to achieve mutual cooperation.
