Perceptions of an individual can change dramatically across different images of their face. Questions remain as to whether some traits are more sensitive to image variability than others. To investigate this issue, we constructed a database of 340 naturalistic images consisting of 20 photos of 17 individuals. In this preregistered study, 95 participants rated all 340 images on one of three traits: trustworthiness, dominance, or attractiveness. Across images, participants' trustworthiness ratings tended to vary more than dominance, which in turn varied more than attractiveness; however, the relative differences between traits depended on the identity in question. Importantly, despite the variability in ratings within identities, there were substantial differences between individuals, suggesting that these trait judgements are based to some degree on relatively invariant facial characteristics. We found greater between-identity variability for attractiveness judgements compared to trustworthiness and dominance. Future research should further investigate the extent to which each trait dimension is tied to the identity of the faces.
个体的感知在不同的面部图像中可能会发生巨大变化。人们仍然不清楚某些特征是否比其他特征更容易受到图像变化的影响。为了研究这个问题，我们构建了一个由 340 张自然主义图像组成的数据库，其中包括 17 个人的 20 张照片。在这项预先注册的研究中，95 名参与者对所有 340 张图像中的三个特征之一进行了评分：可信度、支配力或吸引力。在不同的图像中，参与者的可信度评分往往比支配力评分变化更大，而支配力评分又比吸引力评分变化更大；然而，特征之间的相对差异取决于所涉及的身份。重要的是，尽管身份内部的评分存在差异，但个体之间存在着很大的差异，这表明这些特征判断在某种程度上是基于相对不变的面部特征。我们发现，与可信度和支配力相比，吸引力判断的个体间变异性更大。未来的研究应该进一步探讨每个特征维度与面部身份的关联程度。
