The impact of emotional expressions on children’s trust judgments

ABSTRACT Research on the development of selective trust has shown that young children do not indiscriminately trust all potential informants. They are likely to seek and endorse information from individuals who have proven competent or benign in the past. However, research on trust among adults raises the possibility that children might also be influenced by the emotions expressed by potential informants. In particular, they might trust individuals expressing more positive emotion. Indeed, young children’s trust in particular informants based on their past behaviour might be undermined by their currently expressed emotions. To examine this possibility, we tested the selective trust of fifty 4- and 5-year-olds in two steps. We first confirmed that children are likely to invest more trust in individuals expressing more positive emotion. We then showed that even if children have already formed an impression of two potential informants based on their behavioural record, their choices about whose claims to trust are markedly influenced by the degree of positive emotion currently expressed by the two informants. By implication, the facial emotions expressed by potential informants can undermine young children’s selective trust based on the behavioural record of those informants.
