在社会交往中，人们会根据微妙的面部线索迅速自动地判断他人的可信度。为了研究这些判断的行为和神经相关性，我们进行了两项研究：一项研究是构建和评估一组可信度不同的自然面孔（研究1：n = 30），另一项研究是调查事件相关电位（ERP）对这组自然面孔的反应（研究2：n = 30）。这两项研究的参与者提供了高度可靠和几乎相同的可信度评级所选择的面孔，支持的概念，值得信赖和不值得信赖的面孔的歧视取决于不同的面部线索。这些线索似乎是在一个自动和自下而上驱动的方式处理，因为这些面孔的自由观看是足够的，以引起信任相关的差异，晚期正电位（LPPs）所示的较大幅度不值得信赖的相比，值得信赖的脸。两者合计，这些研究结果表明，自然的面孔包含不同的线索，自动和快速处理，以促进在各种情况下的不值得信赖和值得信赖的面孔的歧视，大概是通过加强精心处理的不值得信赖的面孔相比。
During social interactions, individuals rapidly and automatically judge others' trustworthiness on the basis of subtle facial cues. To investigate the behavioral and neural correlates of these judgments, we conducted 2 studies: 1 study for the construction and evaluation of a set of natural faces differing in trustworthiness (Study 1: n = 30) and another study for the investigation of event-related potentials (ERPs) in response to this set of natural faces (Study 2: n = 30). Participants of both studies provided highly reliable and nearly identical trustworthiness ratings for the selected faces, supporting the notion that the discrimination of trustworthy and untrustworthy faces depends on distinct facial cues. These cues appear to be processed in an automatic and bottom-up-driven fashion because the free viewing of these faces was sufficient to elicit trustworthiness-related differences in late positive potentials (LPPs) as indicated by larger amplitudes to untrustworthy as compared with trustworthy faces. Taken together, these findings suggest that natural faces contain distinct cues that are automatically and rapidly processed to facilitate the discrimination of untrustworthy and trustworthy faces across various contexts, presumably by enhancing the elaborative processing of untrustworthy as compared with trustworthy faces.
