【摘要】 社会比较又称人际比较,是一个获取社会信息、评估社会信息和回应社会信息的加工过程,个体将储存在记忆中的比较信息与自我信息进行对比,进而获得自我定位和自我评估。竞争关系是组织中常见的关系形式之一,是指人们为了争夺共同目标或占据有利地位而形成的互相求胜的关系形式。社会比较在组织中如何影响结果评价、公平感知的研究主要集中在奖赏加工方面,近年来,研究者们对社会比较影响奖赏加工的认知机制和神经机制研究开展了大量研究,而竞争情境作为组织中人际互动的重要环境变量,却未得到研究者们的关注。本研究的目的在于探讨社会比较中竞争情境对奖励加工影响的神经机制。实验采用修正的点估计任务范式,使用ERPs技术记录被试完成点估计任务后获取奖励反馈的脑电成分。结果发现个体在社会比较中对奖励反馈呈现出的时程加工特点如下:有竞争情境比无竞争情境诱发更大波幅的P2和P3;无竞争情境比有竞争情境诱发更负的FRN;奖励高于对手比低于对手诱发更大波幅的P3。该研究证实竞争情境的存在会增强个体与对手比较时的动机水平,更关注自己所获奖励的公平性。更多还原

【Abstract】 Social comparison is also called interpersonal comparison,it is a information processing process that obtain social information,evaluation of social information and response to social information,which mean is that individual make comparative information stored in memory compare to self information,thus acquiring self positioning and self evaluation.Compete relationship is one of common forms of relationships in the organization,means that the form of mutual win relationship was set up for the common goal or a good position.The research field about how social relationship impacted on outcome assessment and justice perception were focus on award processing,in recent years,a large number researches were carried out for cognitive mechanism and neural mechanism of social comparison affect on award processing.But there is a variable haven’t get researchers attention that is compete relationship,which is a important environment variable during interpersonal interaction in organization.The purpose of this research is that explore the neural mechanism of social comparison affect on reward processing. Experiment using the fixed dot estimation task,and using ERPs technology records the electrical components when participants looking the feedback of reward information after they compared with another opponent.The purpose of this study is to explore social comparison competition situation in the neural mechanism of the impact of reward processing.Experiments using fixed point estimation task paradigm,using ERPs technology records the participants get a reward after feedback point estimation task electrical components.The results found that reward processing during social comparison showed the calendar processing characteristics as follows:(1) relative to no competition situation,competition situation induced larger amplitude of P2 and P3;(2) relative to competition situation,no competition situation more negative FRN;(3) relative to higher reward than opponent,lower reward than opponent induced larger amplitude of P3.The research confirmed that the existence of competition situation will enhance individual motivation level when compared with opponent,and take individual more attention on reward fairness.更多还原
