识别一个人的身份是指导社会交往的基础。我们可以通过看一个人的脸来识别她的身份，也可以通过听她的声音来识别。一个重要的问题是，视觉和听觉信息如何结合在一起，使我们能够独立于刺激的形式来识别身份。本研究报告收敛的证据，在单变量对比和多变量分类表明，后上级颞沟（pSTS），以前已知的编码多模态的视觉和听觉表示，编码信息的人的身份与不变性内和跨模态。特别是，pSTS显示了对面部的选择性，对声音的选择性，在视觉模态内跨图像变换的面部身份分类，以及跨模态的个人身份分类。(C)2017爱思唯尔有限公司版权所有
Recognizing the identity of a person is fundamental to guide social interactions. We can recognize the identity of a person looking at her face, but also listening to her voice. An important question concerns how visual and auditory information come together, enabling us to recognize identity independently of the modality of the stimulus. This study reports converging evidence across univariate contrasts and multivariate classification showing that the posterior superior temporal sulcus (pSTS), previously known to encode polymodal visual and auditory representations, encodes information about person identity with invariance within and across modality. In particular, pSTS shows selectivity for faces, selectivity for voices, classification of face identity across image transformations within the visual modality, and classification of person identity across modality.
