社会认知中的一个主导主题是，人们通常通过根据他们所属的社会群体对他人进行分类来简化个人感知过程。然而，尽管有大量文献记载了这种策略的认知益处，但仍存在一些未解决的问题。特别是，类别匹配对人的分类过程有多重要？知觉者对范例典型性的变化敏感吗？使用侧翼任务和变形面部刺激，我们通过检查从两个种族类别（即，亚洲人和高加索人）在不同程度上混合在一起。结果表明，参与者确实是敏感的范例典型性的变化，即使他们的注意力并没有明确地指向关键的触发刺激。这一发现的理论和实践意义被认为是。
A dominant theme in social cognition is that people routinely simplify the person perception process by categorizing others on the basis of the social groups to which they belong. However, despite an extensive literature documenting the cognitive benefits of this strategy, a number of unresolved issues remain. In particular, how important is categorical fit to the process of person categorization? Are perceivers sensitive to variations in exemplar typicality? Using a flanker task and morphed facial stimuli, we investigated this issue by examining the extent to which categorical information is extracted from faces in which the features of two racial categories (i.e., Asian and Caucasian) are blended to varying degrees. The results revealed that participants are indeed sensitive to variations in exemplar typicality, even when their attention is not explicitly directed to the critical triggering stimuli. The theoretical and practical implications of this finding are considered.
