面孔与躯体的情绪可以合二为一吗?——整合效应及其神经机制

The Integrated Effect of Face-body Emotional Information and Its Neural Mechanism

面孔、躯体都能表达和传递情绪信息,有效整合两种视觉线索的情绪信息是正常人际交往和社会互动的必要条件。面孔与躯体的情绪整合效应,既体现为二者情绪一致时情绪加工的促进作用,又表现为面孔-躯体情绪整合相较于单一情绪线索的加工优势。面孔-躯体情绪整合主要涉及面孔与躯体的构型编码、情绪加工及与动作知觉相关的脑区和通路。本文提出了涵盖“三个子过程”和“三个阶段”的情绪整合层级模型。今后的研究应进一步关注自闭症、抑郁症等临床个体的情绪整合加工,揭示神经系统“如何”整合动态视觉情绪信息,探究视觉情绪整合加工特点等问题。

Both face and body can express and convey emotional information.Effective integration of emotional information of the two visual cues is a necessary condition for regular interpersonal and social communication.The emotional integration effect of face and body is reflected not only in promoting emotional processing when the two emotions are consistent but also in the advantage of face-body emotional integration over single emotional cues.Face-body emotional integration mainly involves face and body configuration coding,emotional processing,brain regions,and pathways related to motion perception.This paper presents an emotional integration hierarchy model covering the“three sub-processes”and“three stages”.Future research should pay more attention to the emotional integration processing of clinical individuals such as autism and depression,reveal“how”the nervous system integrates dynamic emotional visual information,and explore the characteristics of emotional visual integration processing.
