Adults prefer to interact with others that are similar to themselves. Even slight facial self-resemblance can elicit trust towards strangers. Here we investigate if preschoolers at the age of 5 years already use facial self-resemblance when they make social judgments about others. We found that, in the absence of any additional knowledge about prospective peers, children preferred those who look subtly like themselves over complete strangers. Thus, subtle morphological similarities trigger social preferences well before adulthood.
成年人更喜欢与和自己相似的人交往。即使是轻微的面部自我相似性也能引发对陌生人的信任。在这里,我们研究5岁的学龄前儿童在对他人进行社会判断时是否已经会利用面部自我相似性。我们发现,在对潜在同伴没有任何额外了解的情况下,孩子们更喜欢那些与自己有细微相似之处的人,而不是完全陌生的人。因此,细微的形态相似性在成年之前就会引发社会偏好。
