公平作为人类社会最重要的社会规范之一,对于个人生存和社会稳定至关重要。人类具有不公平厌恶倾向(inequity aversion),当受到不公平对待时,会产生不满和怨恨,并不惜牺牲自己的经济利益以惩罚对方。以往研究发现,不公平感知(unfairness perception)会降低个体对不公平实施者的信任,但目前尚不清楚这种影响是否会泛化到对无关陌生人的信任(即是否出现溢出效应)?此外,除了亲身经历不公平对待,人们还会作为旁观者在日常生活中观察到不公平行为。当观察到不公平行为且该行为没有受到惩罚时,是否也会降低个体对无关陌生人的信任?本研究通过两项实验对上述问题进行了探讨。研究1采用单因素被试间实验设计,通过最后通牒游戏(ultimatum game),操纵提议者分钱方案公平性,诱发公平和不公平情境,并通过随后的信任游戏(trust game)考察个体对无关陌生人的信任行为。研究2同样采用单因素被试间实验设计,让被试作为观察者,观察独裁者游戏(dictator game)中的公平和不公平分配行为,并通过随后的信任游戏考察个体对无关陌生人的信任行为。结果表明:(1)在先前的最后通牒游戏中... 相似文献

采用最后通牒博弈范式,考察利益水平及社会距离对个体公平加工的影响,探讨公平加工的情境依赖性。实验结果表明:(1)对分配提议的加工受到利益水平的调节,不利不公平条件下被试更加注重公平。(2)提议的不同水平影响被试的拒绝行为,提议越不公平,拒绝率越高。(3)虽然社会距离的主效应不显著,但在实际情境中,较近的社会距离下人们对公平的要求更严格,证实公平加工具有情境依赖性。 相似文献

在最后通牒博弈中,自利动机与公平偏好的权衡决定着个体拒绝或者接受不公平分配。根据双系统理论,对于个体拒绝不公平分配是系统1中的自动反应还是系统2中的控制加工这一争议,从理论假说、影响因素和脑机制三个方面进行了探讨。自动消极互惠假说和社会启发假说支持公平偏好的自动加工假说,公平偏好控制假说则认为公平偏好是抑制自利动机的控制加工的结果。系统1通过脑岛、杏仁核和腹内侧前额叶皮层识别和评估公平行为;系统2通过扣带回皮层、腹外侧、背内侧和背外侧前额叶皮层,对系统1进行重新评估和调节并做出相应的决策。个体差异因素和实验任务特征可能会影响个体在系统1中的自动反应。未来研究需要进一步完善实验范式,深入探索其中的调节变量及其神经网络。 相似文献

公平加工的情境依赖性:来自ERP的证据 总被引:1,自引:0,他引:1
公平是人类社会生活的重要概念。大量研究采用最后通牒博弈, 发现人们具有不公平厌恶倾向, 即宁愿牺牲个人的经济利益, 也要拒绝不公平的分配提议。已有研究表明, 损失情境会增强不公平厌恶, 但其神经机制尚不清楚。本实验采用ERP技术, 运用最后通牒博弈范式, 考察两个情境因素:域(损失或获益)和博弈对象(人或计算机)对公平加工的影响。发现损失域下对不公平分配的拒绝率更高, 而博弈对象对决策行为无影响; 获益域下, 对家为人比对家为计算机诱发了更负的N1; 人机博弈时, 获益域比损失域诱发了更大的P2和LPP, 损失域比获益域、不公平提议比公平提议诱发了更大的N350, 而公平提议比不公平提议诱发了更大的LPP; 人际博弈时, 这些差异均不显著。这些结果表明, 对分配提议的大脑加工受博弈对象的调节, 人际博弈时, 对损益域、公平与不公平提议的加工类似, 而人机博弈时, 损失域和不公平提议涉及更多的抑制加工和冲突解决, 获益域和公平提议则更富动机性意义, 证实公平加工具有情境依赖性。 相似文献

大量研究采用最后通牒博弈发现人们愿意牺牲自身利益来维护公平,普遍具有不公平厌恶倾向。本文基于行为博弈任务对个体处于不同角色时的公平行为,从神经学层面做出新的解释,并对现存理论模型做了梳理。脑成像的研究发现,公平行为的相关脑区主要有负责情绪加工的脑岛和与认知控制相关的背外侧前额叶,内侧眶额皮层。前脑岛激活越大,个体拒绝不公平方案的可能性越大,而腹外侧前额叶可以调节前脑岛的活动,使个体采取更理性的方式,接受不公平分配方案。另外,睾酮素和催产素作为神经调节的激素,可以对公平行为起到调节作用,睾酮素通过抑制内侧眶额皮层的激活,增加对不公平方案的拒绝率,相反,催产素可以降低个体对于不公平方案的拒绝率,并增加个体的公平行为。 相似文献

研究发现,人们普遍具有追求公平的偏好,即人们在追求个人收益时也会关注收益分配的公平性。随着电生理技术的发展,越来越多的研究者采用电生理技术对公平偏好进行深入探讨。本研究从脑电、皮肤电、心电等方面梳理公平偏好的电生理机制。脑电的研究发现,公平偏好相关的脑电主要涉及反馈相关负波和P300;皮肤电的研究发现,相比于公平分配,个体在不公平分配情况下其皮肤电的激活水平更高;心率的研究发现,相比于公平分配,个体遭遇不公平分配时其心率降低。研究公平偏好电生理机制有助于更深入地揭示公平偏好的产生根源与形成过程。未来可从公平偏好电生理的整合研究、公平偏好的脑成像与电生理的整合性探索,以及拓展公平偏好电生理的外部效度和研究范式等方面展开进一步探究。 相似文献

社会公平从古至今都是人类追求的崇高社会理想。对社会公平的感知即社会公平感直接决定着个体的机构信任,并影响其公共合作参与。本研究将社会公平感分为分配公平和程序公平,将机构信任度分为工具信任和动机信任,采用实验室情境设计的方法,引入最后通牒博弈和免责博弈范式,通过2个实验系统探讨"公正无私,一言而万民齐"的因果机制。研究发现分配公平与程序公平正作用于个体的公共合作态度与意向,在此基础上建立起公共合作的双路径模型:外部路径由分配公平产生工具信任和动机信任,进而触发公共合作;内部路径由程序公平产生动机信任和工具信任,进而触发公共合作;二者结合构成个体参与公共合作的双动力系统。双路径模型的适用性在组织情境和社会情境下均得到了支持。 相似文献

There is ample experimental evidence showing that people have a strong preference for equity in wealth allocation and social interaction. Although the behavior of gain sharing and responses to (un)fairness in allocation of wealth has been extensively investigated in studies employing economic exchange games, few studies have focused on how people respond to an unfair division of loss between individuals. In this study we developed a new variant of the ultimatum game and examined the participants' reactions to (un)fairness in both gain and loss sharing. Results from three experiments showed that the rejection rates to unfair offers were generally higher in the loss than in the gain domain. Moreover, participants were inclined to associate loss with “unfair” and gain with “fair”, with stronger associations leading to higher rejection rates in the ultimatum game. Furthermore, in subjective rating, unfair offers were perceived as being more unfair in the loss than in the gain domain. These results demonstrate an increased demand for fairness under adversity and the importance of justice in liability sharing. 相似文献

本研究借助经典的最后通牒博弈范式(UG)和独裁者博弈范式(DG),将回应者/接受者作为研究对象,考察了不同公平条件、平等条件下社会排斥对社会决策的影响作用。实验结果发现:(1)在面对高不公平性的分配方案时,被排斥组比被接纳组更倾向于拒绝接受该分配方案;(2)被排斥组对高不公平性分配方案的满意度要显著低于被接纳组;(3)被排斥组在不平等的博弈(DG)条件下对分配方案的满意度显著低于平等博弈(UG)条件下对分配方案的满意度。本研究结果说明,社会排斥情境下的被试对公平与平等因素更加敏感:在高不公平条件下,被排斥的个体表现出更少的合作互惠行为,甚至不惜放弃自身经济利益,也要惩罚博弈对方的不公平行为;此外,在不平等的博弈条件下,被排斥的个体产生了更多的消极情绪体验。本文的研究结果提高了社会决策研究的生态效度和传统决策模型的预测效度,有利于更加完整透彻地了解社会决策的影响因素。 相似文献

Standard economic models assume people exclusively pursue material self‐interests in social interactions. However, people exhibit social preferences; that is, they base their choices partly on the outcomes others obtained in a social interaction. People care about fairness, and reciprocity affects behavior. This study examines the differences in negative reciprocity (costly punishment for unfair divisions) as a function of age. Sixty‐one kindergarteners (5‐year‐olds), 53 second graders (8‐year‐olds), and 57 sixth graders (12‐year‐olds) played a dictator game or a mini–ultimatum game either with a human proposer or with a random machine that determined the division between the two players. By keeping the divisions between the players constant and varying the source of the unfair proposal, we were able to differentiate between reciprocity‐based and inequality‐aversion preferences. We found that kindergarteners proposed and accepted unfair divisions regardless of the source of the offer, behaving according to the standard economic model. Children in the sixth grade tended to reject unfair offers from a human proposer but accept unfair divisions from a random device, indicating the emergence of negative reciprocity preferences by age eight (and contrary to inequality aversion). Children at this age also tended to give more fair offers in the ultimatum game than in the dictator game, indicating the emergence of strategic thinking.

Previous research has shown that affective empathy, rather than cognitive empathy, significantly predicts people’s altruistic sharing behavior in economic games. However, most of these studies were conducted in Western populations. There might be cultural differences in the relations between empathy and altruism due to different levels of empathy between Western and Asian individuals. In this study, we measured different aspects of empathy in Chinese adults as well as their allocation offers in the dictator and ultimatum games. We found that cognitive empathy, but not affective empathy, was a significant predictor of adults’ altruistic sharing behavior in the two economic games. Subjective family income was also revealed to be a significant predictor of individuals’ altruism in the ultimatum game, such that people with lower subjective family income tended to be more generous. Potential implications of our findings are discussed. 相似文献

Research examining both the organizing and activating effects of testosterone in one-shot bargaining contexts has been vexed by inconsistencies. Some research finds that high-testosterone men are more likely to reject unfair offers in an ultimatum game and exogenous administration of testosterone to men leads to less generous offers. In contrast, other research finds that higher prenatal exposure to testosterone predicts more generous dictator game offers and administering testosterone to women leads to more generous ultimatum game offers. The current research seeks to resolve these inconsistencies by examining how the organizing effects of testosterone affect bargaining behavior. Because testosterone is associated with status seeking and concerns with social reputation, we hypothesized that testosterone would predict aggressive bargaining but only after provocation. Two studies found that prenatal testosterone exposure, as measured by 2D:4D ratio, led to aggressive responses for both males and females, but only after they received unfair offers. Furthermore, perceptions of fairness violations moderated but did not mediate the effect of testosterone on retributional responding. These results suggest that the organizing effects of testosterone have consistent effects on bargaining behavior for both males and females but its predictive ability requires some form of provocation to emerge. 相似文献
