Which theory posits that sleep solidifies memories and supports learning?

• A. Restoration theory
• B. Activation-synthesis theory
• C. Memory organization and consolidation theory
• D. Learning rehearsal theory

Answer: (C)

Sleep helps solidify memories and support learning through the process of memory consolidation and reorganization. During sleep, especially slow-wave sleep and REM, the brain replays recent experiences, strengthening the hippocampal connections and gradually integrating them into cortical networks. This stabilizes memories, makes retrieval more reliable, and helps connect new information with what you already know, which is why getting adequate sleep after studying often leads to better learning. Other theories don't focus on this consolidation process. The restoration view emphasizes physical restoration rather than memory changes. Activation-synthesis explains dreams as the result of random brain activity, not memory organization. A “learning rehearsal” idea suggests practice happens during sleep, but the strongest current framework centers on how sleep reorganizes and strengthens memory traces to support learning.
