Preschoolers selectively trust and selectively share with others based on their past accuracy and intentions.

This study investigated whether preschool-age children consider both an individual's past accuracy and intentions when deciding whether to trust and share with that individual. The participants, 3- to 5-year-olds (N = 168), played a searching game with partners who varied in both accuracy (accurate or inaccurate) and intentions (prosocial or antisocial). Children received advice from partners about where to look for a hidden object, earning prizes for correct guesses. Then they were given an opportunity to share their prizes with their partner. Results indicated that children trusted sources who provided accurate advice (regardless of intentions) and shared with sources who provided accurate advice or demonstrated prosocial intentions. These findings suggest that children attend to both an individual's accuracy and intentions when deciding how to interact with social partners and may weigh this information differently to make different social decisions.
