Abstract：本研究考察对他人可信程度的感知是否会影响对该人物面孔长相的表征及其潜在的机制。实验1让被试形成目标人物可信或不可信的印象。随后利用反相关图像分类技术将被试对目标人物面孔的心理表征可视化。结果发现无论目标人物是男性还是女性, 高可信度的目标人物与更具吸引力和积极特质的面孔表征相关。实验2从一批新的被试中可视化了可信和不可信群体的面孔表征的特征, 并与实验1中获得的目标人物的面孔表征的特征做相似性分析, 发现被描述为可信(或不可信)的目标人物的面孔表征特征与可信(或不可信)群体的面孔表征特征有更多的相似性, 说明当人们得知他人是可信(或不可信)时, 会把脑海中的对应图式特征叠加到该人物的面孔物理特征上, 从而重塑面孔表征。本研究说明自上而下的加工方式在面孔表征形成中扮演了重要作用。

Abstract： This study examined whether the perception of an individual’s trustworthiness influenced the mental representation of that face and its underlying mechanisms.
In Experiment 1, participants were instructed to develop an opinion about a target person’s trustworthiness, perceiving him/her as either trustworthy or untrustworthy. Then, the reverse correlation image classification technology was employed to visualize participants’ mental representations of the target person’s face. The results showed that regardless of the target person’s gender, those described as highly trustworthy were associated with more positive and attractive facial representations.
In Experiment 2, group’s facial mental representation features of trustworthy and untrustworthy faces were compared with those of the target person from Experiment 1. The results revealed that the face representation features of the target people described as trustworthy (or untrustworthy) had more similarities with those of trustworthy (or untrustworthy) groups.
The findings indicated that when people perceive an individual as trustworthy (or untrustworthy), they would superimpose the corresponding schema features in their minds on the physical characteristics of the perceived individual’s face, leading to a reconfiguration of the face representation. Overall, our study underscores the importance of top-down factors in shaping face representations.
