概要 OBJECTIVES: This study examined the roles of the insula and the anterior cingulate activations in the rejection of unfair offers in the impunity game.METHODS: Fifteen participants played the impunity game in ten trials as responders during neuroimaging.RESULTS: About 45% of the unfair offers were rejected by the responders even when responders could not restore a fair outcome, which cannot be accounted for by social preference of inequity aversion. Imaging data showed that the right anterior insula was activated when participants faced and rejected unfair offers.CONCLUSIONS: The insula activation during a rejection of the unfair offers is the reflection of an emotional response, rather than social preference of inequity aversion. The role of emotion in the neuroeconomics of fairness was demonstrated.
