摘　　要：采用事件相关技术,探讨在合作任务中,决策对象和分配方式如何影响个体公平评价的时间进程。使用2(决策对象:自我、群体)×2(分配方式:按贡献分配、平均分配)被试内设计。结果发现自我决策比为群体决策诱发更大的P2和更小的FRN;自我决策时,按贡献分配诱发的P3显著小于平均分配诱发的P3;为群体决策时,两种方式诱发的P3无显著差异。结果表明决策对象在早期阶段被优先加工与考虑,而晚期阶段的公平评价受到决策对象和分配方式的联合调节。By using event related potential (ERPs) technique, this paper discusses how decision objects and distribution methods affect the time process of individual fairness evaluation in cooperative tasks. The experiment adopts the within-subject design of 2 (decision objects: oneself, the group) × 2 (distribution methods: contribution distribution, equal distribution). Making decisions for themselves induces larger P2 and small FRN than for groups. When individuals made decisions for themselves, the P3 induced by contribution distribution was significantly smaller than that induced by equal distribution, while made decisions for their own groups, there was no significant difference between two kinds of distribution methods. The results show that the decision-making object is given priority to be processed and considered in the early stage, while the fair evaluation in the late stage is jointly regulated by the decision-making object and the distribution methods.
