Abstract：
Human societies benefit from social norms that increase cooperation and support social order. Hence, the understanding of effective mechanisms enforcing norms is crucial. One of such mechanisms is \"third-party punishment\" (TPP) - a form of social punishment that could be delivered by a third-party, not directly affected by the actions of the norm violator. Previous electrophysiological studies (ERP) reported that perceived violations of norms evoked the medial frontal negativity in third-parties. The current study further probed the link between the medial frontal negativity (MFN) and actual TPP of norm violation, as it was not shown directly before. Participants played a dictator game as third-parties, being able to select different levels of punishment of an unfair violator\'s decisions. We replicated previous findings and showed the amplitude of the MFN correlated with the intensity of TPP (Fz, r = -0.516, p = 0.034, FCz, r = -0.509; p = 0.037). Overall, our findings further support the direct link between the MFN and the intensity of TPP.
摘要：
人类社会受益于增加合作和支持社会秩序的社会规范。因此，对执行规范的有效机制的理解至关重要。其中一种机制是“第三方惩罚”(TPP)——一种可以由第三方实施的社会惩罚形式。不受违反者行为的直接影响。先前的电生理研究（ERP）报告说，违反规范的行为会引起第三方的内侧额叶负性。当前的研究进一步探讨了内侧额叶负性（MFN）与实际违反规范的TPP之间的联系，因为它之前没有直接显示。参与者作为第三方玩独裁者游戏，能够对不公平违反者的决定选择不同程度的惩罚。我们复制了以前的发现，并显示了最惠国待遇的幅度与TPP的强度相关(Fz，r=-0.516,p=0.034,FCz,r=-0.509；p=0.037）。总的来说,我们的研究结果进一步支持最惠国待遇与TPP强度之间的直接联系。
