The human "person" is a common percept we encounter. Research on person perception has been focused either on face or body perception-with less attention paid to whole person perception. We review psychological and neuroscience studies aimed at understanding how face and body processing operate in concert to support intact person perception. We address this question considering: a.) the task to be accomplished (identification, emotion processing, detection), b.) the neural stage of processing (early/late visual mechanisms), and c.) the relevant brain regions for face/body/person processing. From the psychological perspective, we conclude that the integration of faces and bodies is mediated by the goal of the processing (e.g., emotion analysis, identification, etc.). From the neural perspective, we propose a hierarchical functional neural architecture of face-body integration that retains a degree of separation between the dorsal and ventral visual streams. We argue for two centers of integration: a ventral semantic integration hub that is the result of progressive, posterior-to-anterior, face-body integration; and a social agent integration hub in the dorsal stream STS.
人类“个体”是我们经常遇到的一个普遍概念。个体知觉的研究要么集中在面孔知觉上，要么集中在身体知觉上，而对整体个体知觉的关注较少。我们回顾了旨在理解面部和身体处理如何协同运作以支持完整个体知觉的心理学和神经科学研究。我们从以下三个方面来考虑这个问题：a）要完成的任务（识别、情绪处理、检测），b）处理的神经阶段（早期/晚期视觉机制），以及 c）用于面部/身体/个体处理的相关脑区。从心理学的角度来看，我们的结论是，面部和身体的整合是由处理的目标（例如，情绪分析、识别等）介导的。从神经科学的角度来看，我们提出了一个分层的功能性面部-身体整合神经结构，保留了背侧和腹侧视觉流之间的一定程度的分离。我们认为有两个整合中心：腹侧语义整合中心，是逐步的、从后向前的、面部-身体整合的结果；以及背侧 STG 中的社会代理整合中心。
