AP PSYCHOLOGY

Detailed explanation-1: -Sleep terrors are a disorder of arousal, meaning they occur during N3 sleep, the deepest stage of non-rapid eye movement (NREM) sleep. Another NREM disorder is sleepwalking, which can occur together with sleep terrors. Various factors can contribute to sleep terrors, such as: Sleep deprivation and extreme tiredness.

Detailed explanation-2: -Sleepwalking (somnambulism) most often occurs during deep, non-REM sleep (called N3 sleep) early in the night. Sleepwalking is much more common in children and young adults than in older adults.

Detailed explanation-3: -Non rapid eye movement (NREM) parasomnias are abnormal behaviors arising primarily but not exclusively during non-REM stage three (N3) sleep. Phenotypes include sleepwalking, sleep terrors, confusional arousals, sexsomnia, and sleep-related eating disorder (SRED).

Detailed explanation-4: -Sleepwalking happens during non-REM (NREM) sleep, usually in stage III of the sleep cycle, which is also known as deep sleep. Along with other parasomnias like sleep talking, confusional arousals, and sleep terrors, sleepwalking is classified as an NREM disorder of arousal.

Detailed explanation-5: -Night terrors are caused by over-arousal of the central nervous system (CNS) during sleep. Sleep happens in several stages. We have dreams-including nightmares-during the rapid eye movement (REM) stage. Night terrors happen during deep non-REM sleep.
