Attachment, Parent–Child Discourse and Theory-of-Mind Development

This study investigated the relations among attachment, mother–child discourse, and theory of mind in a sample of 76 four‐year‐old children (mean age = 4.48 years; 36 boys). Mother–child conversations about a past event were coded for maternal use of elaborative discourse and mothers' references to mental states. Mothers completed the attachment q‐sort and children completed four false‐belief tasks. Results revealed that maternal conversational elaboration was a significant predictor of children's theory‐of‐mind performance, whereas maternal mental state references and attachment security were not. The findings provide further evidence for the importance of discourse in children's theory‐of‐mind development.
