Reactivation refers to the process of reviving or restoring previously learned information, memories, or skills that have become dormant or forgotten. This can occur in various contexts, such as in cognitive psychology, neuroscience, or education. Reactivation may involve the deliberate retrieval of stored information or the unconscious activation of dormant memories through cues or triggers. Researchers study reactivation to understand how memory works, how learning occurs, and how individuals can optimize their retention and recall of information. Reactivation is believed to be a crucial component of memory consolidation and can potentially enhance long-term memory storage and retrieval.
