This article reviews empirical research that investigates memory of trauma that occurred in infancy and very early childhood. The authors considered 9 articles in which children and adults' memory presentations were described and compared with 3rd-party documentation of traumatic events. The 9 studies reviewed have emerged from multiple perspectives, including psychoanalytic theory, trauma theory, neuropsychology, cognitive science, and nursing theory. Based on these articles, in which approximately 150 cases of early trauma are represented, the authors summarize the findings regarding the nature of memory for infant and very early childhood traumas and highlight points of agreement and disagreement among clinicians and researchers.
