在信任博弈中，受托人的面部信任度和反馈信息会影响委托人的投资行为。本研究探讨了结果评价（评价反馈）的时间特征及其对面孔信任加工的影响。共有25名大学生参加了一项决策任务，其中反馈之前，面对刺激。对参与者继续投资的决定进行了评价。我们观察到，委托人更倾向于继续投资于值得信赖的受托人或那些在积极反馈（收益）后出现的受托人。事件相关电位（ERP）结果显示，在面孔呈现阶段，损失的可信面孔比损失的可信面孔和损失的不可信面孔诱发更多的负反馈相关负性（FRN）。此外，没有达到预期的面孔会引起更多的负面FRN。值得信赖的面孔与收益诱导更多的积极的晚期积极成分（LPC）比值得信赖的面孔与损失，并产生更多的动机性注意。在不同的阶段，自下而上和自上而下的面部信任感知过程相结合。综上所述，自上而下的加工对面孔信任感的早期影响较大，自上而下和自下而上的加工对面孔信任感的中期影响较大，自下而上的加工对面孔信任感的后期影响较大。
Facial trustworthiness and feedback information of trustees can influence trustors’ investment behavior in trust games. This study investigated the temporal features of outcome evaluation (evaluation of feedback) and how they influence the processing of facial trustworthiness. A total of 25 college students participated in a decision-making task in which feedback was presented prior to a face stimulus. The decision of participants to continue investing was evaluated. We observed that trustors were more inclined to keep investing in trustworthy trustees or those appearing after positive feedback (gains). Event-related potential (ERP) results revealed that in the face presentation stage, trustworthy faces with losses induced more negative feedback-related negativity (FRN) than did trustworthy faces with gains and untrustworthy faces with losses. Further, faces that did not meet expectations induced more negative FRN. Trustworthy faces with gains induced more positive late positive component (LPC) than did trustworthy faces with losses and generated more motivated attention. Bottom–up and top–down processes were integrated for facial trustworthiness perception at different stages. In sum, top–down processing exerted a greater impact during the early stage of facial trustworthiness perception, both top–down and bottom–up processing were involved in the medium term, and bottom–up processing exerted a greater impact in the later stage.
