Forensic investigations involving children carry heavy consequences and often present immense challenges. Most child maltreatment allegations first occur in an informal setting, where young witnesses discuss legally relevant information with parents before official interviews. After decades of developmental research on how various qualities of formal interviews can shape children’s forensic reports, a growing body of work examining parent–child memory-sharing exchanges demonstrates that informal conversations with others outside of investigative interviews are a powerful source of mnemonic influence. Not only can suggestions offered by parents intrude into children’s later independent accounts, they also can lead children to make novel and elaborate reports of nonoccurring events. Despite the potency of parental conversations on children’s recollections, children typically fail to recognize parents as the source of memory errors. We offer suggestions for future research and legal practice.
