Example Questions
Example Question #531 : Individual Psychology And Behavior
Which hormone is most closely associated with sleep?
Melatonin
Adrenaline
Estrogen
Oxytocin
Testosterone
Melatonin
Melatonin is released by the pineal gland in response to circadian rhythms and other environmental clues, like darkness. It causes drowsiness and helps induce sleep.
Example Question #532 : Individual Psychology And Behavior
During which stage of sleep do night terrors occur?
Stage 4
REM Sleep
Stage 1
Stage 2
Stage 3
Stage 4
Night terrors are characterized by high arousal and an appearance of being terrified. Stage 4 is our deepest sleep stage, so it is difficult for those with night terrors to escape their terror by waking up (unlike nightmares).
Example Question #533 : Individual Psychology And Behavior
Which brain waves are associated with deep sleep?
Alpha waves
Beta waves
Iota waves
Gamma waves
Delta waves
Delta waves
Delta waves occur during deep sleep (stage 4) and are associated with dreaming. In contrast, alpha waves are relatively slow brain waves that occur during a relaxed, awake state.
Example Question #6 : Biology Of Sleep
What is the average amount of sleep adults get each night?
6 hours
8 hours
7 hours
10 hours
8 hours
The average amount of sleep an adult gets is 8 hours. Everyone is different, however; where some adults function off of 6 hours, others need at least 9 hours or more to feel healthy and awake.
Example Question #534 : Individual Psychology And Behavior
What functions are directly related to circadian rhythm?
Hair and skin health, weight, and muscle restoration
Blood pressure, metabolism, and body temperature
Mental functioning, hormones, and physical fitness
Heart, intestinal, and skin health
Blood pressure, metabolism, and body temperature
Circadian rythm is responsible for the cycles of our blood pressure, metabolism, and body temperature. It contributes to our levels of energy throughout the day and is responsible for our descension in sleepiness as night falls.
Example Question #2 : Biology Of Sleep
What is stage 2 of the sleep cycle?
5-10 minute phase, during which we can be easily awakened
Phase 2 sleep happens 90 minutes after you fall asleep and corresponds to deep, resorative REM sleep
None of these
Light sleep phase, during which a drop in body temperature occurs
Light sleep phase, during which a drop in body temperature occurs
After stage 1, which lasts about 5-10 minutes, is stage 2 during which we slowly enter deep sleep. This stage is still considered light sleep, corresponds to a drop in body temperature. We can still be woken up fairly easily. Stage 3 is when we enter heavier, deep sleep.
Example Question #535 : Individual Psychology And Behavior
Which of the following can occur during REM sleep?
Intense dreams
All of these
Quickened breathing
Quickened heart rate
All of these
REM is arguably the most important stage of sleep, and it is the last stage of our sleep cycle until it repeats all over again. Due to the heightened activity in our brains, we may have more intense dreams during this period. Also during this time, our heart rate and breathing quickens, and our body restores itself.
Example Question #536 : Individual Psychology And Behavior
What is insomnia?
A psychological disorder in which an underlying trauma keeps one awake at night
A sleep disorder in which the affected person's circadian rythm is disrupted to the point that the body does not know when it should be asleep
A sleep disorder in which the affected person may not be able to fall asleep, and keeps waking up during the night
A psychological disorder in which the affected person cannot sleep due to paranoid or obsessive thinking
A sleep disorder in which the affected person may not be able to fall asleep, and keeps waking up during the night
Insomnia is a sleep disorder in which the affected person may not be able to fall asleep, and keeps waking up during the night. It affects a significant percentage of Americans, and is mostly caused by stress or some other underlying condition. It is often treated with medications or behavioral therapy.
Example Question #12 : Cognition And Consciousness
Which of the following follows a circadian rhythm?
Eating
Drug absorption
Learning
Dreaming
Sleep
Sleep
A circadian rhythm is any process that abides by a 24-hour rhythm. It is best known for helping to tell our bodies when they need sleep. Having a disrupted circadian rhythm is related to negative health outcomes, including various neurological and cardiological problems.
Example Question #537 : Individual Psychology And Behavior
When are hypnagogic sensations most likely to be experienced?
REM
NREM-2
NREM-4
NREM-3
NREM-1
NREM-1
Sleep occurs in 4 stages, NREM-1, NREM-2, NREM-3, and REM.
It's during the first stage of sleep (NREM-1) that you may experience images that resemble hallucinations. These experiences occur without a sensory stimulation and can sometimes be later incorporated into one's memories.
