[SUMMARY] Young children can learn from other’s testimony. This study examined the effect of informant’s smiles, a cue not always directly related to reliability, on selective trust in preschool children aged 4-6. Children（N = 78, Mage = 68.35 months）were asked to decide if they could eat the novel foods based on the informant’s testimony. The results showed that young children used both informant’s accuracy and smile to rate trusty. Although the informant’s facial expression is not preferred over the accuracy, children, particularly younger ones, most often trusted informants who smiled and were always correct. This study provides important implications for the attitudes of parents and caregivers that support young children’s learning of appropriate knowledge.
