面部表情的类别知觉及其个体差异

面部表情类别知觉效应是指连续变化的表情在人脑中按照类别表征, 且不同类别的表情之间存在明显的类别界线。介绍了面部表情类别知觉效应的行为和脑电研究范式及基础研究, 综述了攻击性、抑郁症、精神分裂症、社交焦虑等对面部表情类别知觉的影响, 以及面部表情类别知觉的发展研究。综述表明, 类别知觉研究能够揭示不同人群表情知觉类别界线及其偏移情况, 有助于解释相应的社会行为。未来研究应注重对面部表情类别知觉效应的个体差异和神经生理机制的探索。

Categorical Perception of Facial Expression and Its Individual Differences

Categorical perception (CP) effect of facial expression is that facial expressions varying continuously are perceived in human brain as belonging to qualitatively discrete categories, with a clear categorical boundary between different emotional expressions. In this paper, the behavior and ERP experiment paradigms and the fundamental research were introduced, and the influence on CP effect of facial expression of aggression, depression, schizophrenia as well as social anxiety disorder and the developmental research of CP were summarized. The review indicates that CP research could reveal the categorical boundary and its deviation of emotional perception among different individuals, which contributes to the explanation of their corresponding social behaviors. Future research should pay more attention to the individual difference and neural mechanism underlying CP effect of facial expression.
