先前的研究表明，社交距离(例如，成为朋友或陌生人)会影响人们的公平考虑和关心他人的行为。然而，社交距离如何影响接受者对(不)公平行为的评价还不完全清楚。在这项研究中，我们让人们玩一个独裁者游戏，在这个游戏中，他们从朋友或陌生人那里收到(不公平的)提议，同时记录他们的大脑潜力。结果表明，内侧额叶负波(MFN)是一个与预期违规相关的成分，它对不公平的朋友提议的反应比对朋友的公平提议更消极，而对陌生人的提议没有表现出不同的反应。无论是朋友还是陌生人提供的服务，P300对于公平的服务都比对不公平的服务更积极。这些结果表明，违反社会规范的行为可以在评估过程的早期阶段被发现，而且这种发现可以受到社会距离的调节。(C)2011爱思唯尔B.V.保留所有权利。
Previous research showed that social distance (e.g., being friends or strangers) influences people's fairness consideration and other-regarding behavior. However, it is not entirely clear how social distance influences the recipient's evaluation of (un)fair behavior. In this study, we let people play a dictator game in which they received (un)fair offers from either friends or strangers while their brain potentials were recorded. Results showed that the medial frontal negativity (MFN), a component associated with the processing of expectancy violation, was more negative-going in response to unfair than to fair offers from friends whereas it did not show differential responses to offers from strangers. The P300 was more positive for fair than for unfair offers irrespective of friends or strangers making the offers. These results suggest that violation of social norms can be detected at an early stage of evaluative processing and that this detection can be modulated by social distance. (C) 2011 Elsevier B.V.
