AP Psych Sleep Stages and Dreams
33 flashcards covering AP Psych Sleep Stages and Dreams for the AP-PSYCHOLOGY Unit 2: Biological Bases section.
The topic of sleep stages and dreams is a critical component of AP Psychology, as defined by the College Board's AP Psychology Curriculum Framework. This area explores the various stages of sleep, including REM and non-REM sleep, and the psychological functions of dreaming. Understanding these concepts is essential for grasping how biological processes influence behavior and mental states.
In practice exams and competency assessments, questions on sleep stages and dreams often require students to identify and differentiate between the various stages of sleep or explain the significance of dreaming. Common traps include confusing the characteristics of REM sleep with those of non-REM sleep or misinterpreting the functions of dreams. It is important to pay attention to the specific wording of questions, as slight variations can lead to incorrect answers.
A key point that professionals often overlook is the impact of sleep quality on overall mental health, which can significantly influence performance and decision-making in the workplace.

- 01
What are the stages of sleep identified in the sleep cycle?
The stages of sleep include NREM (Non-Rapid Eye Movement) stages 1, 2, 3, and 4, followed by REM (Rapid Eye Movement) sleep. NREM stages progress from light sleep (stage 1) to deep sleep (stage 3 and 4), while REM sleep is associated with vivid dreaming. (College Board AP CED)
- 02
How long is a typical sleep cycle?
A typical sleep cycle lasts about 90 minutes, during which a person progresses through the various stages of sleep, including both NREM and REM stages. (College Board AP CED)
- 03
What is the primary characteristic of REM sleep?
The primary characteristic of REM sleep is rapid eye movement, increased brain activity, and vivid dreaming, which is essential for memory consolidation and emotional processing. (College Board AP CED)
- 04
What occurs during NREM stage 3 sleep?
During NREM stage 3 sleep, also known as deep sleep, the body experiences slow brain waves (delta waves), and it is difficult to awaken the sleeper. This stage is crucial for physical restoration and growth. (College Board AP CED)
- 05
How does sleep architecture change across the night?
Sleep architecture changes across the night, with longer periods of REM sleep occurring in the later cycles, while deep sleep (NREM stage 3 and 4) predominates in the earlier cycles. (College Board AP CED)
- 06
What is the function of sleep according to the restoration theory?
According to the restoration theory, sleep serves to restore and rejuvenate the body and mind, allowing for physical recovery and memory consolidation. (College Board AP CED)
- 07
What is the significance of sleep spindles?
Sleep spindles are bursts of brain activity that occur during NREM stage 2 sleep and are believed to play a role in memory consolidation and cognitive processing. (College Board AP CED)
- 08
What is the impact of sleep deprivation on cognitive function?
Sleep deprivation negatively impacts cognitive function, leading to decreased attention, impaired memory, and reduced problem-solving abilities. (College Board AP CED)
- 09
How often should adolescents aim for sleep per night?
Adolescents should aim for 8 to 10 hours of sleep per night to support optimal physical and mental health. (College Board AP CED)
- 10
What is the relationship between sleep and dreaming?
Dreaming primarily occurs during REM sleep, where the brain is highly active, and is thought to play a role in processing emotions and experiences. (College Board AP CED)
- 11
What are the physiological changes during REM sleep?
During REM sleep, physiological changes include increased heart rate, irregular breathing, and temporary muscle paralysis, which prevents acting out dreams. (College Board AP CED)
- 12
What is the role of the suprachiasmatic nucleus in sleep regulation?
The suprachiasmatic nucleus (SCN) regulates circadian rhythms, influencing sleep-wake cycles by responding to light cues and controlling melatonin production. (College Board AP CED)
- 13
What is the difference between REM and NREM sleep?
REM sleep is characterized by rapid eye movement and vivid dreaming, while NREM sleep is divided into stages of light to deep sleep without eye movement and less dreaming. (College Board AP CED)
- 14
What are common sleep disorders associated with REM sleep?
Common sleep disorders associated with REM sleep include REM Sleep Behavior Disorder (RBD) and narcolepsy, which can disrupt normal sleep patterns and dreaming. (College Board AP CED)
- 15
How does age affect sleep patterns?
As individuals age, total sleep time often decreases, and the proportion of deep sleep (NREM stage 3 and 4) also declines, leading to lighter sleep. (College Board AP CED)
- 16
What is insomnia and its potential causes?
Insomnia is a sleep disorder characterized by difficulty falling or staying asleep, which can be caused by stress, anxiety, medical conditions, or lifestyle factors. (College Board AP CED)
- 17
What is the function of dreaming according to the activation-synthesis theory?
The activation-synthesis theory posits that dreaming results from the brain's attempt to make sense of random neural activity during REM sleep, creating a narrative from these signals. (College Board AP CED)
- 18
What are the stages of NREM sleep?
NREM sleep consists of three stages: stage 1 (light sleep), stage 2 (moderate sleep with sleep spindles), and stages 3 and 4 (deep sleep characterized by delta waves). (College Board AP CED)
- 19
How does sleep affect memory consolidation?
Sleep, particularly REM sleep, plays a crucial role in memory consolidation by processing and integrating new information into existing memory networks. (College Board AP CED)
- 20
What is sleep apnea and its symptoms?
Sleep apnea is a sleep disorder characterized by repeated interruptions in breathing during sleep, leading to excessive daytime sleepiness, loud snoring, and difficulty concentrating. (College Board AP CED)
- 21
What is the relationship between sleep and mental health?
There is a bidirectional relationship between sleep and mental health; poor sleep can exacerbate mental health issues, while mental health disorders can disrupt sleep patterns. (College Board AP CED)
- 22
What is the role of melatonin in sleep regulation?
Melatonin is a hormone produced by the pineal gland that regulates sleep-wake cycles by signaling the body that it is time to sleep, typically increasing in response to darkness. (College Board AP CED)
- 23
What is the impact of light exposure on sleep?
Exposure to light, especially blue light from screens, can disrupt the production of melatonin, delaying sleep onset and negatively affecting sleep quality. (College Board AP CED)
- 24
What is the typical duration of REM sleep per night?
Typically, REM sleep accounts for about 20-25% of total sleep time, which translates to approximately 90-120 minutes in a full night of sleep. (College Board AP CED)
- 25
What is narcolepsy and its primary symptoms?
Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks, often accompanied by cataplexy and disrupted nighttime sleep. (College Board AP CED)
- 26
How does caffeine affect sleep?
Caffeine is a stimulant that can interfere with sleep by blocking adenosine receptors, which promote sleepiness, leading to difficulty falling asleep and reduced sleep quality. (College Board AP CED)
- 27
What is a sleep study and its purpose?
A sleep study, or polysomnography, is a diagnostic test that records brain waves, oxygen levels, heart rate, and breathing during sleep to identify sleep disorders. (College Board AP CED)
