DESCRIPTION (provided by applicant): The goal of the proposed research is to investigate how social category information such as race, gender, and age affect the perception of faces. This will be done by drawing on work from two related yet not-well-integrated lines of research. The first deals with early perceptual processing of faces, and the second focuses more generally on impression formation. Research in the former tradition has not often addressed the role of social category information whereas work in the latter tradition has not addressed how early perceptual processes affect outcomes such as stereotyping and prejudice. Preliminary research we have done using event-related brain potentials (ERPOs) shows that target race and gender have multiple discrete effects on the processing of faces beginning as early as 100 ms after stimulus onset (Ito & Urland, in press). Moreover, these effects differ throughout the time course of processing. Based on this, the working hypothesis of the proposed research is that social category membership affects the perception of faces at very early stages of processing, and that it has different effects as processing progresses. Studies are proposed that (a) assess the degree to which the perception of social category membership is a multi-staged process, (b) examine whether a single model can account for processing of different group dimensions, and (c) assess how early perceptual aspects of face processing relate to stereotyping and prejudice. More generally, the proposed research will integrate models from cognitive neuroscience on face perception with social psychological models of social perception with the ultimate goal of better understanding the full time course of how social cues are extracted from faces and later affect the activation of stereotypes and prejudice.

描述（由申请人提供）：拟议研究的目标是调查种族、性别和年龄等社会类别信息如何影响面孔的感知。这将通过利用两个相关但尚未充分整合的研究领域的工作来完成。第一个涉及面部的早期感知处理，第二个更普遍地关注印象的形成。前一种传统的研究并不经常解决社会类别信息的作用，而后一种传统的研究则没有解决早期感知过程如何影响诸如刻板印象和偏见等结果。 我们使用事件相关大脑电位 (ERPO) 进行的初步研究表明，目标种族和性别早在刺激发生后 100 毫秒就开始对面部处理产生多种离散影响（Ito 和 Urland，正在出版）。此外，这些影响在整个处理过程中是不同的。基于此，本研究的工作假设是，社会类别成员资格会在处理的早期阶段影响对面孔的感知，并且随着处理的进展，它会产生不同的影响。建议进行研究（a）评估社会类别成员资格的感知是一个多阶段过程的程度，（b）检查单一模型是否可以解释不同群体维度的处理，以及（c）评估早期感知如何面部处理的各个方面与刻板印象和偏见有关。更一般地说，拟议的研究将把面部感知的认知神经科学模型与社会感知的社会心理学模型相结合，最终目标是更好地理解如何从面部提取社会线索并随后影响刻板印象和偏见的激活的整个过程。 。
