人类躯体与人类面孔相似:是由各个部位按照一定的空间关系组成,并且是对称的。它也能提供个体身份和行为方式等信息,如年龄、性别、意图、情感状态等。它与面孔相辅相成,共同促成对个体身份的辨别。躯体知觉是指大脑对进入视觉加工系统中的人类躯体刺激的侦察,感知或识别。躯体知觉应当如面孔知觉研究一样受到更多的关注。文章概述、评价了与躯体知觉相关的认知神经研究,着重介绍了躯体知觉的认知和神经机制,并提出了一些值得进一步研究的问题。
Similar to the human face, human body is symmetrical. It is composed by parts' location according to certain spatial relationships. Human body can provide information of individual's identity, age, sex, intention, emotional state, and so on. Perceptions of body together with perceptions of face promote individual's identity discrimination. Body perception refers to the detection, perception or recognition about the visual human body stimuli. Body perception, just as face perception, should receive more attention in scientific research. The purpose of the article is to outline and evaluate cognitive and neural studies about body perception. This article mainly focuses on the cognitive and neural mechanisms of body perception. Finally, the article proposed a number of open issues for future research. The studies of human body perception are new. Limited research literatures make it difficult for researchers to get an accurate inference on the neural mechanisms of human body perception. Future studies also need to address the following questions. It is uncertain whether the recognition of the human body is also based on a configural processing mechanism. But this view about human body perception has been supported by the findings based on a number of different methods of cognitive neuroscience (behavioral research methods, neuropsychological research methods, fMIR methods), it is worthwhile to further research in this field. In addition, it is also unclear whether the configural processing is the continuous or parallel operation. Future studies need to clarify the exact operational style of these types about configural processing and to explore which type is more fit to human body recognition. Although both the body processing and face processing present inversion effect, they may be different in the mechanisms that dominated the processing to produce different effects. We need to further explore whether we can use the processing mechanism of face inversion to explain the mechanism of the body inversion
