Multiple facial cues such as facial expression and face gender simultaneously influence facial trustworthiness judgement in adults. The current work was to examine the effect of multiple facial cues on trustworthiness judgement across age groups. Eight‐, 10‐year‐olds, and adults detect trustworthiness from happy and neutral adult faces (female and male faces) in Experiment 1. Experiment 2 included both adult and child faces wearing happy, angry, and neutral expressions. Nine‐, 11‐, 13‐year‐olds, and adults had to rate facial trustworthiness with a 7‐point Likert scale. The results of Experiments 1 and 2 revealed that facial expression and face gender independently affected facial trustworthiness judgement in children aged 10 and below but simultaneously affected judgement in children aged 11 and above, adolescents, and adults. There was no own‐age bias in children and adults. The results showed that children younger than 10 could not process multiple facial cues in the same manner as in older children and adults when judging trustworthiness. The current findings provide evidence for the stable‐feature account, but not for the own‐age bias account or the expertise account.

基于多个面部线索的面部可信度判断中的年龄差异

成年人的面部表情和面部性别等多种面部提示会同时影响成年人的面部可信赖度判断。当前的工作是检验多个面部提示对不同年龄组的可信赖性判断的影响。在实验1中，八岁，十岁的成年人和成年人从幸福和中性的成人面孔（女性和男性面孔）中检测出信任度。实验2包括成年人和孩子的面孔，都戴着快乐，愤怒和中性的表情。九岁，十一岁，十三岁和成年人必须使用7点李克特量表对面部信任度进行评分。实验1和2的结果表明，面部表情和面部性别独立影响10岁及以下儿童的脸部可信度判断，但同时影响11岁及以上儿童，青少年和成年人的判断力。儿童和成人没有年龄差异。结果表明，在评判可信度时，年龄小于10岁的儿童无法以与较大的儿童和成人相同的方式处理多种面部暗示。目前的发现为稳定特征账户提供了证据，但没有为年龄偏见账户或专业知识账户提供证据。
