Faces vary from image to image, eliciting different judgements of traits and often different judgements of identity. Knowledge that two face images belong to the same person facilitates the processing of identity information across images, but it is unclear if this also applies to trait judgements. In this preregistered study, participants ( = 100) rated the same 340 face images on perceived trustworthiness, dominance, or attractiveness presented in randomised order and again later presented in sets consisting of the same identity. We also explored the role of implicit person theory beliefs in the variability of social judgements across images. We found that judgements of trustworthiness varied less when images were presented in sets consisting of the same identity than in randomised order and were more consistent for images presented later in a set than those presented earlier. However, knowledge of identity had little effect on perceptions of dominance and attractiveness. Finally, implicit person theory beliefs were not associated with variability in social judgements and did not account for effects of knowledge of identity. Our findings suggest that knowledge of identity and perceptual familiarity stabilises judgements of trustworthiness, but not perceptions of dominance and attractiveness.
人脸在不同的图像中会有所变化，从而引发对特征的不同判断，而且通常也会引发对身份的不同判断。知道两张人脸图像属于同一个人，这有助于在不同的图像中处理身份信息，但尚不清楚这是否也适用于特征判断。在这项预先注册的研究中，参与者（n=100）对随机呈现的 340 张面孔图像的可信任度、支配力或吸引力进行了评价，之后又以同一身份的集合形式再次进行了评价。我们还探讨了内隐人格理论信念在图像间社会判断变异性中的作用。我们发现，当图像以同一身份的集合形式呈现时，其可信任度的判断变化较小，而在集合中呈现的图像比之前呈现的图像更一致。然而，身份知识对支配力和吸引力的感知影响很小。最后，内隐人格理论信念与社会判断的变异性无关，也不能解释身份知识的影响。我们的研究结果表明，身份知识和感知熟悉度可以稳定可信任度的判断，但不能稳定对支配力和吸引力的感知。
