The Development of 3-to 5-Year-olds' Trust Judgment Based on Face

The present study investigated the developmental changes in the ability to make trust judgements based on strangers' face. A total of 262 children aged 3- to 5-year-olds were asked to make trust judgments in two studies.The results showed:( 1) When children were showed by only one face of stranger,4-to 5-year-olds could use facial characters to make trust judgment,but 3-year-olds' performances were in the random level;( 2) When children were showed with the trustworthy and untrustworthy faces simultaneously during the trust-related interaction situations,3-to 5-year-olds could make trust judgment based on face,and the accuracy of judgments increased with age. In conclusion,these findings suggested that children from 3-year-olds could make trust judgments based on face druing the initial interactions,and the ability of trust judgment was improved with age.
