Oksana Zinchenko, Research Fellow at the Institute of Cognitive Neuroscience, HSE University, has conducted meta-analysis of 17 articles to find out which areas of the brain are involved in decision-making for rendering social punishment. It would appear that in case of both victims of violations as well as witnesses, punishment decisions activate the brain regions responsible for focusing one’s attention, processing information, and responding effectively to social interaction. The findings of the study were published in Scientific Reports.
Social punishment is necessary in order to maintain order and cooperation in society. In their everyday lives, people who have committed wrongdoings may face reprimand or rejection. A decision to invoke punishment may be implemented by a person who was affected because of such a violation of norms (‘second-party punishment’), or by a neutral person, who nevertheless knows about the norm violation (‘third-party punishment’). It used to be a known fact that certain brain areas activate in victims of violations as well as in witnesses in response to different forms of social punishment. However, it was not entirely clear to date which areas were activated in particular.
A typical game for the study of social punishment is the Ultimatum where one test subject makes a decision about how much of the amount given to him or her will be given to another subject. The participant is free to divide the sum up as he or she likes, even keeping the entire amount. If the second participant finds the decision unfair, they can punish the offender (for example, reject the proposed division), i.e. execute ‘second party punishment’. Alternatively, the punishment can be invoked by the third test subject, the witness of the transaction, which will constitute third-party punishment.
