瞳孔大小反映了观察者的认知和情感状态，从而形成了人际印象。瞳孔放大的人比瞳孔缩小的人更受肯定。本研究探讨瞳孔放大在建立人际信任中的作用。我们使用了Okubo et al.（2017）拍摄的面部照片，其中模型（N= 81）在经济游戏中显示的照片中被视为可信赖的人。我们用图像处理软件测量了每个模特的瞳孔直径。当模特们在脸上表现出值得信赖时，瞳孔就会放大。此外，经济游戏中不可信的选择预示着瞳孔放大。由于放大的瞳孔会产生积极的印象，结果表明瞳孔放大可能与隐藏可信度信号有关。不值得信任的人可能会使用瞳孔反应，几乎无法自主控制，以利用他人在社会交往。
Pupil size reflects the cognitive and affective states of the beholder and thus shapes interpersonal impressions. Individuals with dilated pupils are evaluated more positively than those with constricted pupils. The present study investigated the role of pupil dilation in building interpersonal trust. We used face photographs taken by Okubo et al. (2017), in which models (N= 81) were posed as trustworthy persons for a photograph shown in an economic game. We measured the pupil diameter of each model’s photographs using image processing software. The pupils were dilated when the models expressed trustworthiness in their faces. Moreover, untrustworthy choices in an economic game predicted pupil dilation. As dilated pupils produce positive impressions, the results suggest that pupil dilation may be associated with concealing signals of trustworthiness. Untrustworthy individuals may use pupillary responses almost incapable of voluntary control to exploit others in social interactions.
