中文摘要：

个体往往会基于面孔特征对他人进行特质推断和社会评价，这种推进和评价会影响个体的行为决策。结合印象形成的双加工理论和面孔加工的双通路模型，本文提出陌生面孔的印象加工主要包括两类方式：一是基于社会分类线索及相似特征的加工，激活个体的刻板印象；二是基于熟悉面孔的相似性特征线索，通过过度泛化激活与熟悉他人相一致的印象。本文进一步阐述了两类面孔线索印象加工的过程和影响陌生面孔印象加工的相关因素。在此基础上，本文提出现有的研究对两类加工方式的交互作用及其加工阶段尚未作深入探讨，同时指出知觉者本人的人格特质和面孔信息对印象加工的影响也需要在未来研究中进一步探索。

英文摘要：

We often form impressions on the characteristics of others from single, and static samples of their appearance. It is the very first thing we see when, or even before, we meet them. And these impressions influence decisions that people make in a variety of important domains, such as mate choice, employment, pro-social behaviors and so on （Zebrowitz ＆ Montepare, 2008）. As an important cue to form impressions, faces usually bring rich social information （Zhang ＆ Zhu, 2012）. Both of the two main models of dual processing theories on impressions, the continuum model and the dual-process model, emphasized the role of social category and the specific individual information in impression processing （Fisk ＆ Neuberg, 1990）. The face recognition model of Bruce and Young proposed that there were two routes to process facial characteristics, based on identity-nonspecific （including social category） or identity- specific information （Bruce ＆Young, 1986）. Comparing the theories of dual processing on impressions with the face recognition model of Bruce and Young, one may suggest that processing of unknown impressions may rely on two kinds of facial information, the social category or similar characteristics and familiar faces characteristics. On the one hand, some researchers proposed that social category and stereotypes processing might be two separated processes. The social category actually is a cue to activate stereotypes （Zhang ＆ Zuo, 2012）. However, even face itself does not possess obvious characteristics of social category; individuals can also activate stereotypes based on similar social category characteristics （Zebrowitz ＆ Montepare, 2008）. On the other hand, people could not directly get information from an unknown face to form impressions. However, the similarity between a face and a familiar face could be a cue, which could help us to form consistent social evaluations and trait inference from the familiar face （Gawroski ＆ Quiun, 2013; Verosky ＆ Todorov, 2010, 2013?
