AP PSYCHOLOGY

Detailed explanation-1: -These individual differences in circadian patterns of activity are known as a person’s chronotype. A person’s individual chronotype may show that a person has a greater propensity to sleep earlier and wake up earlier (a morning lark), or to stay up late and sleep in (a night owl).

Detailed explanation-2: -Figure 4.1 EEG patterns change with each stage of sleep. In Stage II, the EEG shows different kinds of brain waves bursting in synchrony.

Detailed explanation-3: -What does it indicate if a sleeper’s EEG shows long, slow, high-amplitude waves? Most neurons are active in synchrony with one another.

Detailed explanation-4: -Language switcher. Circadian rhythm disorders, also known as sleep-wake cycle disorders, are problems that occur when your body’s internal clock, which tells you when it’s time to sleep or wake, is out of sync with your environment. Your internal clock, called a circadian clock, cycles about every 24 hours.
