个人简介：

Dr. Frank Krueger is Associate Professor of Systems Social Neuroscience at the School of Systems Biology at George Mason University. He is Chief of the Social Cognition & Interaction: Functionalism & Immersion (SCI:FI) Lab and Co-Director of the Center for the Study of Neuroeconomics. As a psychologist and neuroscientist, Dr. Krueger is interested in understanding the psychological functions (i.e., why they exist and work) and the proximate neurobiological mechanisms (i.e., how they work) of social cognition (e.g., beliefs, schemata) and social interactions (e.g., trust, reciprocity) combining methods from social psychology, behavioral economics, and social neuroscience.

主要内容：

Social punishment is a sanction of deviant behavior of others that violates the social norms recognized and accepted by the group, which enabled the intense social cooperation enjoyed by our ancestors— despite their genetic heterogeneity. The range of social punishment is driven by only two factors: the wrongdoer's intention and the harm caused to the victim. Neuroscientists are accumulating evidence that is beginning to build a neuropsychological model of social punishment based on the assumption that third-party punishment (TPP, individuals incur costs to punish norm violators, even when they are not themselves the victims of the violations) is an evolutionary extension of second-party punishment (SPP, victims themselves retaliating against their aggressors). Here, we performed a coordinate-based meta-analysis implementing the activation likelihood estimation method to determine similar and different consistent brain regions activated for SPP and TPP. Next, we investigated the similarities and differences of the connectivity patterns of these regions using task-based meta-analytic connectivity mapping and task-free resting-state functional connectivity analyses —as different connectivity patterns may indicate the presence of different brain modules underlying distinct functional roles. Finally, we implemented hierarchical clustering of the meta-analytic connectivity to examine the convergence of these connectivity profiles. Our result provided evidence that TPP and SPP involve similar neural and cognitive mechanisms, and that TPP may indeed represent a form of punishment that has evolved from older and more widespread forms of SPP. Further, we showed that TPP and SPP preferentially recruit different brain regions. However, we point out that the sharp, functional dichotomy of these brain regions supposed in the literature may be a simplification of a far more complex picture. In conclusion, we provide an emerging neuropsychological model of social punishment that may help future researchers to better characterize the underlying dynamics of social norm enforcement and shed light someday on the difficult question about how we should treat the serious wrongdoers among us.
