Young children's understanding of conflicting mental representation predicts suggestibility

This study examined the relation between developmental suggestibility effects and preschoolers' emerging ability to reason about conflicting mental representations (CMRs). Three- to 5-year-olds listened to a story accompanied by pictures. Following a 4-min delay, children answered straightforward and misleading questions about the story. One week later, their memory for the story was assessed. Children also completed tasks indexing their ability to reason about CMRs. Stepwise regression analyses revealed that suggestibility was negatively related to performance on CMR tasks. This finding remained significant after controlling for age, children's level of initial encoding of the event, and their ability to retrieve event details when not misled. An integration is proposed between children's theory of mind and source monitoring that may help to explain early developmental changes in suggestibility.
