面孔社会知觉中的表情效应

面孔社会知觉指知觉者基于面孔所有者的面孔信息对面孔所有者的人格特质等进行知觉推断的过程。表情是人们进行面孔社会知觉的关键线索之一。表情可以单独通过本身的局部特征和结构信息影响面孔社会知觉, 还可以通过对知觉者的情绪诱发或表情传达的行为倾向性来影响面孔社会知觉的结果。考虑到现实生活中多种表情类型的组合及特定表情(伪装表情)高频出现以及知觉者判断人格特质存在主观性, 未来研究要加强多种表情类型对面孔社会知觉的影响研究, 还要进一步将知觉者因素作为未来研究的变量。

Effects of expression on social perceptions of faces

Social perceptions of faces refer to the process in which people perceive others' social characteristics (e.g., personality) based on their face information. Facial expression plays a key role in social perceptions of faces. The local features and structural information are the main factors affecting social perceptions of faces. Facial expression can also impact social perceptions of faces by eliciting the perceivers' emotion and their behavioral tendency. In daily life, facial expressions are very complicated. For example, there might be mixture of multiple expressions, as well as fake expressions; on the other hand, social perceptions of faces are of great subjectivity. Further studies should expand the types of facial expression, and take the perceivers' characteristics into account.
