Almost 100 years ago, Freud identified infantile or childhood amnesia, the difficulty that most adults have remembering events from their first years of life. Recent research in cognitive psychology has in fact demonstrated a paucity of verbal memories of early life experiences. Although Freud believed that childhood memories are repressed, modern explanations for childhood amnesia focus instead on cognitive and social developmental advances of the early preschool years. According to the social interaction hypothesis, a narrative sense of self emerges as a result of parent-child conversations about the past. Implications of autobiographical memory research for models of adult attachment and psychotherapy are discussed.
