ABSTRACT Trust begins with our first impression of others. But which matters most in forming the first impression that others possess stereotypically trustworthy facial features, that they look like us, or that they belong to our social group? This study explored the interaction among stereotypical trustworthiness, kinship (based on facial resemblance), and group membership (using arbitrary groups) in the formation of first impressions. Each participant rated 48 stimuli varying in stereotypical trustworthiness (trustworthy vs. untrustworthy), facial resemblance (self vs. other), and group membership (ingroup vs. outgroup) on three traits (trustworthiness, competence, and attractiveness). We observed unique interaction patterns for each of the three traits and we speculate that there is a match between the primacy of the information and the primacy of the evaluated dimension that influences the formation of first impressions. In addition, we propose that group membership may drive first impressions in the absence of kinship information. Our integrative approach brings us closer to understanding the formation of first impressions, and thus trustworthiness and trust, in real-life situations. Our findings outline stimulating directions for further research.

刻板印象的信任度，面部相似度和团体成员在信任度和其他特征方面的相互作用

摘要信任始于我们对他人的第一印象。但是，在形成第一印象时，最重要的是其他人拥有刻板印象可信赖的面部特征，看起来像我们，或者属于我们的社会群体？这项研究探讨了刻板印象的信任度，亲属关系（基于面部相似性）和群体成员资格（使用任意群体）之间在第一印象形成过程中的相互作用。每个参与者对48种刺激进行了评分，其中包括刻板印象的可信赖度（可信赖与不可信赖），面部相似度（自我与其他）以及小组成员资格（小组内与小组外）的三个特征（可信度，能力和吸引力）。我们观察到了三个特质中每个特质的独特相互作用模式，并且我们推测信息的首要性与评估维度的首要性之间存在匹配，从而影响了第一印象的形成。此外，我们建议在没有亲属关系信息的情​​况下，团体成员身份可能会产生第一印象。我们的综合方法使我们更深入地了解现实生活中第一印象的形成，从而了解可信度和信任度。我们的发现概述了进一步研究的积极方向。我们的综合方法使我们更深入地了解现实生活中第一印象的形成，从而了解可信度和信任度。我们的发现概述了进一步研究的积极方向。我们的综合方法使我们更深入地了解现实生活中第一印象的形成，从而了解可信度和信任度。我们的发现概述了进一步研究的积极方向。
