Final answer:
Slow-wave sleep, or stage 3 sleep, contributes to human memory by consolidating memories and strengthening neural connections related to new information. It is essential for effective memory formation and can improve task performance.
Step-by-step explanation:
Slow-wave sleep, also known as stage 3 sleep, plays a crucial role in human memory formation. During this stage of sleep, the brain generates low frequency, high amplitude delta waves. These delta waves help consolidate memories and strengthen neural connections related to new information learned during wakefulness. Slow-wave sleep is essential for effective memory formation and can improve performance on tasks learned before sleep. It is essential for effective memory formation and can improve task performance.
