Question 1

Dreams can occur in
A)REM sleep.
B)NREM sleep.
C)both REM and NREM sleep.
D)none of these.

Accepted Answer

Dreams can occur in both REM (Rapid Eye Movement) sleep and NREM (Non-Rapid Eye Movement) sleep. However, the nature and frequency of dreams differ between these two stages of sleep. Dreaming is more vivid and intense during REM sleep, while dreams during NREM sleep are usually more mundane and less eventful.

Question 2

During sleep,which of the following prevents you from acting out your dreams?
A)lucid dreaming
B)REM sleep paralysis
C)REM sleep behavior disorder
D)somnambulism

Accepted Answer

During REM sleep, our brains become highly active but our bodies are essentially paralyzed to prevent us from acting out our dreams. This is known as REM sleep paralysis. Lucid dreaming is when the dreamer is aware they are dreaming and can sometimes control their dreams. REM sleep behavior disorder is a disorder in which the paralysis that occurs during REM sleep is incomplete or absent, leading to the individual physically acting out their dreams. Somnambulism, or sleepwalking, occurs during non-REM sleep and is characterized by walking or performing other activities while still asleep.

Question 3

Concerning REM sleep,which of the following statements is FALSE?
A)Roughly 85 percent of the time,people awakened during REM sleep report having vivid dreams.
B)After studying for a long period,you will remember more if you go to sleep (and get REM sleep)than if you pull an all-nighter.
C)REM sleep is a combination of sleep spindles and very deep delta waves.
D)People who are born blind experience REM sleep.

Accepted Answer

REM sleep is characterized by rapid eye movements and a lack of muscle tone. It is not associated with sleep spindles or delta waves, which are characteristic of non-REM sleep.

Question 4

Observing a subject who is in REM sleep,a researcher can conclude that the subject will exhibit all of the following characteristics EXCEPT
A)vivid dreaming.
B)sexual arousal.
C)voluntary muscle paralysis.
D)delta waves.

Accepted Answer

Delta waves are not typically associated with REM sleep, as they are predominantly observed during deep sleep stages (NREM stages 3 and 4). The other characteristics listed are commonly seen during REM sleep.

Question 5

Carrie is extremely worried about her job.There are rumors of the company planning to downsize,and Carrie's boss has been fussing at everyone she encounters.With this situation,we can expect Carrie to be experiencing
A)less REM sleep.
B)more REM sleep.
C)more NREM sleep.
D)more sleep spindles.

Accepted Answer

When a person is experiencing high levels of anxiety or stress, they often have an increase in REM sleep. This could be because the brain is trying to process and consolidate memories and emotions related to the stressful situation. Therefore, we can expect Carrie to be experiencing more REM sleep.

Question 6

The disorder that is characterized by a failure of normal muscle paralysis,leading to violent actions during REM sleep,is called
A)periodic limb movement syndrome.
B)restless legs syndrome.
C)REM sleep behavior disorder.
D)sleep terror disorder.

Accepted Answer

REM sleep behavior disorder is characterized by a failure of normal muscle paralysis during REM sleep, which can lead to physical actions and even violence. Periodic limb movement syndrome and restless legs syndrome involve repetitive limb movements during sleep, but not necessarily violent actions. Sleep terror disorder involves intense fear or panic during sleep, but not necessarily physical actions.

Question 7

Concerning REM sleep,which of the following statements is TRUE?
A)People who are born blind do not experience REM sleep.
B)Dreams during REM sleep tend to be longer,clearer,more detailed,more bizarre,and more "dream­like" than thoughts and images than occur in NREM sleep.
C)Roughly 85 percent of the time,people who are awakened during REM sleep report having no dreams.
D)REM sleep is shown in reptiles,such as snakes and iguanas.

Accepted Answer

Studies have shown that dreams during REM sleep tend to be longer, clearer, more detailed, more bizarre, and more "dream-like" than thoughts and images than occur in NREM sleep. Option A is incorrect as people who are born blind do experience REM sleep. Option C is also incorrect as studies show that people who are awakened during REM sleep are more likely to report having vivid dreams. Option D is incorrect as REM sleep has only been observed in mammals and birds, not reptiles.

Question 8

Regarding REM sleep,which of the following statements is FALSE?
A)Major muscles appear paralyzed during REM sleep.
B)Males and females display sexual arousal during REM sleep.
C)You usually dream as soon as you enter Stage 1 sleep.
D)Some eye movements during REM sleep correspond to the activities occurring in the dreams.

Accepted Answer

Dreams occur primarily during REM sleep, not Stage 1 sleep.

Question 9

Which of the following dramatically increases when there is a death in the family,trouble at work,a marital conflict,or other emotionally-charged events?
A)deep sleep delta waves
B)beta waves and sleep spindles
C)NREM sleep
D)REM sleep

Accepted Answer

Emotionally-charged events can increase the amount of REM (rapid eye movement) sleep, as the brain processes and integrates the emotional experiences during this stage of sleep.

Question 10

A person in a sleep lab is showing emotional arousal,blood pressure changes,and sexual arousal,which all primarily occur during
A)REM sleep.
B)NREM sleep.
C)delta sleep.
D)Stage 4 sleep.

Accepted Answer

Emotional arousal, changes in blood pressure, and sexual arousal are all commonly associated with REM sleep. During this stage of sleep, the body experiences a range of physiological changes, including increased brain activity, rapid eye movement, and muscle paralysis. These changes are thought to be linked to the processing and consolidation of emotional and cognitive experiences.

Question 11

Daytime stress tends to increase _______ sleep.
A)REM
B)NREM stage 2
C)NREM stage 3
D)NREM stage 4

Accepted Answer

The answer of Daytime stress tends to increase _______ sleep.
A)REM
B)NREM...

Question 12

Regarding REM and NREM sleep,which of the following statements is TRUE?
A)Daytime stress can increase NREM sleep.
B)Physical exertion can increase REM sleep.
C)NREM sleep is deepest early in the night during the first few stage 4 periods.
D)Mammals,such as dogs and cats,do not show REM sleep.

Accepted Answer

NREM sleep is deepest during the first few stage 3 and 4 periods early in the night. Option A is false as daytime stress actually reduces NREM sleep. Option B is false as physical exertion can increase NREM sleep but not REM sleep. Option D is false as mammals, including dogs and cats, do show REM sleep.

Question 13

Regarding REM sleep,which of the following statements is FALSE?
A)REM sleep has a fast,irregular EEG pattern similar to Stage 1 sleep.
B)When measured by an EEG,the brain during REM sleep looks as if the person is awake.
C)Physical exertion tends to increase REM sleep.
D)People who are born blind still experience REM sleep.

Accepted Answer

Physical exertion tends to decrease REM sleep, not increase it.

Question 14

A very stressful day is likely to increase the amount of
A)episodes of sleep apnea.
B)hypersomnia.
C)NREM sleep.
D)REM sleep.

Accepted Answer

A very stressful day is likely to increase the amount of REM sleep. Studies have shown that stress increases the time spent in REM sleep, as the brain processes and consolidates emotional memories during this stage of sleep.

Question 15

Which of the following occurs during REM sleep?
A)irregular heart rate and blood pressure
B)delta waves
C)increased voluntary muscle movement
D)sleepwalking

Accepted Answer

During REM sleep, heart rate and blood pressure tend to become irregular. Delta waves are associated with deep, non-REM sleep. Increased voluntary muscle movement and sleepwalking are more likely to occur during non-REM sleep stages.

Question 16

Compared to NREM,dreams in REM tend to be
A)shorter.
B)more rational and reality-based.
C)clearer and more detailed.
D)characterized by all of these.

Accepted Answer

During REM sleep, our brains are more active and vivid dreams occur. As a result, dreams in REM tend to be clearer and more detailed compared to NREM. They may also be longer than NREM dreams. However, they are not necessarily more rational or reality-based.

Question 17

Concerning REM and NREM sleep,which of the following statements is FALSE?
A)NREM sleep is dream-free about 90 percent of the time.
B)Your first period of Stage 1 sleep usually lacks REMs and dreams.
C)Brain areas associated with imagery and emotion become significantly less active during REM sleep.
D)After studying for a long period,you may remember more if you go to sleep (and get REM sleep)rather than pulling an all-nighter.

Accepted Answer

Brain areas associated with imagery and emotion actually become more active during REM sleep, which is why dreams during this stage tend to be vivid and emotional.

Question 18

Compared to REM,dreams in NREM tend to
A)be longer.
B)be more bizarre and "dream­like."
C)be clearer and more detailed.
D)have none of these characteristics.

Accepted Answer

The answer of Compared to REM,dreams in NREM tend to
A)be...

Question 19

Which of the following is NOT characteristic of REM sleep?
A)irregular heart rate and blood pressure
B)sexual arousal
C)increased voluntary muscle movement
D)rapid eye movements

Accepted Answer

During REM sleep, voluntary muscles are paralyzed, which is why it's also called paradoxical sleep. Therefore, increased voluntary muscle movement is not characteristic of REM sleep.

Question 20

Regarding REM sleep,which of the following statements is FALSE?
A)After studying for a long period,you will remember more if you do not sleep since REM sleep decreases memory formation.
B)Brain areas associated with imagery and emotion become significantly more active during REM sleep.
C)All mammals show REM sleep,but reptiles show no signs of REM sleep.
D)For adults,REM periods add up to about 20 percent of total sleep time.

Accepted Answer

This statement is false as research has shown that sleep, particularly REM sleep, is important for memory consolidation and formation.
