Which theory explains the idea that sleep consolidates memories and reorganizes daytime experiences?

• A. Activation Synthesis
• B. Consolidation Theory
• C. Circadian Rhythm
• D. Psychoactive Drugs

Answer: (B)

Sleep helps stabilize and integrate memories formed during the day, and Consolidation Theory explains this process. During sleep, especially slow-wave sleep and REM, the brain replays daytime experiences and transfers them from the hippocampus to cortical storage, strengthening memory traces and weaving new information into existing networks. This reorganizing turns fragile, short-term memories into durable long-term ones and links new experiences with what we already know. Other ideas place dreams as byproducts of random brain activity (Activation-Synthesis), focus on the timing of sleep (Circadian Rhythm), or describe how substances affect memory, but they don’t account for the specific role of sleep in consolidating and reorganizing memories.
