摘　　要：为了考察在合作任务中,个体对任务结果的比较阶段及分配阶段的脑电变化,本研究采用事件相关电位技术,考察三个任务变量:情境(贡献、责任)、比较(大、小)、分配(贡献原则、平均原则)对合作结果评价的影响。结果发现,责任比贡献诱发更大的FRN和更小的P3;贡献大小诱发的FRN和P3无差异,但责任大比责任小诱发更大的FRN和更小的P3。分配评价阶段,罚金反馈比奖金反馈诱发更大的FRN,基于贡献(责任)分配比基于平均分配的方案诱发出更大的P3。这表明合作背景中仅在责任比较中表现出自我服务偏向,在分配评价阶段未显示自我服务偏向。Using the event-related potential(ERP)technique,the present study investigated how context-based social comparison and distribution affect individuals’outcome evaluation in a cooperative task and their associated EEG responses.Three task variables including context(contribution vs.responsibility),comparison(more vs.less)and distributive principle(equity vs.equality)were manipulated.The results revealed that compared to the contribution based context,responsibility induced larger FRN and smaller P3;furthermore,there was no difference in terms of FRN and P3 induced by more or less contribution.However,the more responsibility condition triggered larger FRN and smaller P3 than the less responsibility condition.In the distribution phase,feedback by monetary penalty elicited larger FRN than feedback by monetary rewards,and the equity based principle elicited larger P3 than the equality based principle.These results indicate that self-service bias appears only in the responsibility comparison rather than the distributive evaluation.
