“…In general, the participants received the allocation after seeing the face of proposer. However, Leng et al (2020b) presented the face of proposer after presenting the fair or unfair allocation plan to the responder, who was played by the participants. They found that compared with the fair allocation plan given by the proposer with a trustworthy face, the unfair allocation plan elicited more negative FRN.…”

“…Individuals can even make decisions on whether a face is trustworthy within a limited time ( Todorov et al, 2008 ). When interacting with a stranger, people may make trustworthiness judgments based on first impressions in a bottom-up way, such as extracting facial cues ( Oosterhof and Todorov, 2008 ; Marzi et al, 2014 ), and then decide whether to cooperate with this person ( Rusman et al, 2012 ; Leng et al, 2020b ). Individuals can trust others and show their own trustworthiness traits to others.…”

“…In tasks involving self-reported trust, participants serving as the trustors are required to judge whether trustees are trustworthy ( Dzhelyova et al, 2011 ; Marzi et al, 2014 ; Calvo et al, 2018 ), or to assess the trustworthiness of the trustees on a scale ( Yang et al, 2011 ; Bailey et al, 2015a , b ). In behavioral trust tasks, participants play an economic game with their partner, such as the trust game ( Chen et al, 2012 ; Qi et al, 2018 ; Leng et al, 2020b ; Li et al, 2021 ) or the ultimatum game ( Osinsky et al, 2014 ). In the trust game, a participant serving as the trustor chooses an amount of money to give to the trustee, and the trustee chooses a certain portion of the doubled amount to return to the trustor.…”

“…In addition to the early face processing components, the middle and late components, such as the FRN (feedback-related negativity) and LPP (late positive potential), are also involved in trust judgments. The FRN, or FN, is a negative wave between 200 and 350 ms that is found in the prefrontal cortex and mainly reflects processing in the feedback stages of economic tasks ( Chen et al, 2012 ; Leng et al, 2020b ). Studies have found that the FRN reflects the difference between the expected results and the actual results.…”

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.
