Psych 101 States of Consciousness Sleep
36 flashcards covering Psych 101 States of Consciousness Sleep for the PSYCHOLOGY-101 Intro Psych Topics section.
The topic of states of consciousness, particularly sleep, encompasses the various stages of sleep, the biological and psychological functions it serves, and the impact of sleep on overall health. This subject is defined within the context of the American Psychological Association's guidelines for introductory psychology courses, which emphasize the significance of understanding sleep patterns and disorders as fundamental components of human behavior.
In practice exams and competency assessments, questions about sleep often focus on the stages of sleep (such as REM and non-REM), the sleep cycle, and the effects of sleep deprivation. Common traps include confusing the characteristics of different sleep stages or underestimating the consequences of inadequate sleep. It's essential to pay attention to the specific details in questions, as they may test both theoretical knowledge and practical implications of sleep-related issues.
A key oversight in clinical practice is the tendency to underestimate the importance of sleep hygiene in patient care, which can significantly affect treatment outcomes.

Most dreaming occurs during REM sleep, which is characterized by rapid eye movements and heightened brain activity (Myers Psychology, Chapter on Sleep).
- 07
What physiological changes occur during REM sleep?
During REM sleep, physiological changes include increased heart rate, irregular breathing, and increased brain activity similar to wakefulness (Hockenbury Psychology, Chapter on Sleep).
- 08
What is insomnia?
Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or waking too early and not being able to return to sleep (Myers Psychology, Chapter on Sleep Disorders).
- 09
What is the primary hormone associated with regulating sleep-wake cycles?
Melatonin is the primary hormone associated with regulating sleep-wake cycles, produced by the pineal gland in response to darkness (Hockenbury Psychology, Chapter on Sleep).
- 10
What is the effect of sleep deprivation on cognitive performance?
Sleep deprivation negatively impacts cognitive performance, including attention, memory, and decision-making abilities (Myers Psychology, Chapter on Sleep).
- 11
What is the sleep stage characterized by deep sleep and the absence of eye movement?
Non-REM (NREM) sleep is characterized by deep sleep, absence of eye movement, and lower brain activity (Hockenbury Psychology, Chapter on Sleep).
- 12
What is sleep apnea?
Sleep apnea is a sleep disorder characterized by repeated interruptions in breathing during sleep, often leading to excessive daytime sleepiness (Myers Psychology, Chapter on Sleep Disorders).
- 13
How does the circadian rhythm influence sleep patterns?
The circadian rhythm influences sleep patterns by regulating the sleep-wake cycle in response to environmental cues like light and darkness (Hockenbury Psychology, Chapter on Sleep).
- 14
What is the term for the temporary inability to move or speak while falling asleep or waking up?
Sleep paralysis is the temporary inability to move or speak while falling asleep or waking up, often accompanied by hallucinations (Myers Psychology, Chapter on Sleep Disorders).

- 16
What behavioral therapy is often used to treat insomnia?
Cognitive Behavioral Therapy for Insomnia (CBT-I) is often used to treat insomnia by addressing thoughts and behaviors that contribute to sleep difficulties (Myers Psychology, Chapter on Sleep Disorders).
- 17
What is the relationship between sleep and memory consolidation?
Sleep plays a critical role in memory consolidation, helping to transfer information from short-term to long-term memory (Hockenbury Psychology, Chapter on Sleep).
- 18
What are sleep spindles?
Sleep spindles are sudden bursts of brain activity that occur during NREM sleep, thought to be involved in memory processing (Myers Psychology, Chapter on Sleep).
- 19
What is the impact of caffeine on sleep?
Caffeine can disrupt sleep patterns by blocking adenosine receptors, which promotes wakefulness and reduces the ability to fall asleep (Myers Psychology, Chapter on Sleep).
- 20
What is the phenomenon where individuals experience vivid dreams during REM sleep?
Vivid dreams are a hallmark of REM sleep, where brain activity is heightened and resembles that of wakefulness (Hockenbury Psychology, Chapter on Sleep).
- 21
What is the primary cause of sleepwalking?
Sleepwalking is primarily caused by genetic factors, sleep deprivation, and disruptions in the sleep cycle, particularly during NREM sleep (Myers Psychology, Chapter on Sleep Disorders).
- 22
What is the effect of light exposure on melatonin production?
Exposure to light, particularly blue light, inhibits melatonin production, which can disrupt sleep-wake cycles (Hockenbury Psychology, Chapter on Sleep).
- 23
What is the term for the period of time it takes to transition from full wakefulness to sleep?
Sleep latency refers to the period of time it takes to transition from full wakefulness to sleep, typically measured in minutes (Myers Psychology, Chapter on Sleep).
- 24
How does age affect sleep patterns?
As people age, they often experience changes in sleep patterns, including lighter sleep and increased awakenings during the night (Hockenbury Psychology, Chapter on Sleep).
