When children make decisions about whom to trust or learn from, they consider not only the informant’s reliability but also the social bond. Previous research often assigned a social label to informants without investigating how the interactive dynamics between informants and children influence learning and trust. This study investigates 3- to 6-year-old children’s preference towards informants who deliver instructions with or without coordination. In two experiments, children evaluated coordinative and non-coordinative informants on game-playing capability, willingness to engage with or learn from the informants, and selective trust in unrelated tasks. Children consistently preferred coordinative informants, perceiving them as more capable and trustworthy, over informants who demonstrated the information without coordinative turn-taking. This preference persisted across age groups, challenging previous notions about children's preference for information completeness. The findings highlight the prosocial effects of coordination, extending its influence beyond peer relationships to significantly impact selective trust when learning from knowledgeable individuals
