Understanding Infantile Amnesia
Infantile amnesia refers to the phenomenon where individuals cannot recall early childhood memories. Studying this puzzling aspect of memory reveals that early memories may be suppressed rather than never formed. Research suggests that memories from infancy are possibly archived but inaccessible, leading to gaps in recollection. Studies on infantile amnesia in mice and toddlers aim to uncover how and why these memories are not readily accessible and the critical periods when memory consolidation occurs.
