基于面部特征的信任感在人际信任和合作行为中起着重要的作用。人际信任行为既涉及委托人，也涉及受托人。然而，对于两个个体的年龄如何影响人际信任行为，目前还没有明确的结论。因此，本研究采用信任博弈任务，探讨了不同年龄组被试对不同年龄面孔反应的信任行为差异，并分析了这种差异在面孔加工阶段是否明显。行为结果表明，只有年轻人比年轻人向年长的伴侣投入更多的钱;也就是说，年轻人更信任年长的面孔。事件相关电位（ERP）分析表明，在面孔加工的早期阶段，年轻面孔比年长面孔诱发更多的负性N170;同时，年长面孔比年轻面孔诱发更多的正性VPP，年轻人比年长者诱发更多的正性VPP。在面孔加工的中后期，年轻面孔比年长面孔在年轻人中引起更多的负FRN，而在老年人中则没有。此外，年长的面孔比年轻的面孔在年长的成年人中引起更多的积极LPP，但在年轻的成年人中没有。神经元分析表明，面孔可信性判断的年龄差异可能发生在面孔加工的后期。结合行为和神经结果，我们发现年轻人和老年人的可信度感知和信任行为之间存在分离，这可能会为如何防止老年人被欺骗提供见解。
Perceived trustworthiness based on facial appearance plays an important role in interpersonal trust and cooperative behavior. Interpersonal trust behaviors involve both trustors and trustees. However, there is no clear conclusion on how the age of the two individuals affects interpersonal trust behaviors. Therefore, this study used the trust game task to explore the differences in trust behaviors between two different age groups in response to faces of different ages and analyzed whether such differences were apparent in the face processing stage. The behavioral results showed that only younger adults invested more money with older partners than younger ones; that is, younger adults trusted older faces more. The event-related potential (ERP) analyses showed that in the early stage of face processing, younger faces elicited more negative N170 than older faces; at the same time, older faces elicited more positive VPP than younger faces, and younger adults had more positive VPP than older adults. In the middle and late stages of face processing, younger faces elicited more negative FRN than older faces in younger adults but not in older adults. In addition, older faces elicited more positive LPP than younger faces in older adults but not in younger adults. The neural analyses suggested that age-related differences in facial trustworthiness judgments might occur in the later stages of face processing. Combining the behavioral and neural results, we found a dissociation between trustworthiness perceptions and trust behaviors in both younger and older adults, which may provide insight into how to prevent older adults from being deceived.
