Which of the following indicates a typical night of sleep for an adult?
A
B
C
D
Which of the following statements about ultradian rhythms during sleep is correct?
Ultradian rhythms during sleep usually last for approximately 60 minutes
Ultradian rhythms during sleep involve less REM sleep as the night progresses
Ultradian rhythms during sleep involve less NREM stage 3 sleep as the night progresses
Ultradian rhythms during sleep usually shorten as the night progresses
REM sleep can be associated with
high levels of movement of the muscles surrounding the eyes.
minimal activity in the brain.
deep sleep
muscle movement.
Recordings from an electromyograph (EMG) can distinguish between rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep because there is
never any movement of the muscles in REM sleep, unlike NREM
never any movement of the muscles in NREM sleep compared to REM
an increase in movement of the muscles in REM sleep compared to NREM
an increase in movement of the muscles in NREM sleep compared to REM
An electroencephalograph (EEG) is used to:
detect, amplify and record electrical activity in the muscles that control eye movement
detect, amplify and record electrical activity in the brain
detect, amplify and record electrical activity in the muscles
measure the movement of the eyes during REM sleep
The use of a sleep diary for research on sleep may generate which type of data?
subjective data
only qualitative data
only quantitative data
inferential data
As a person progresses through the stages of sleep to Stage 3 (deep sleep)
EOG recordings indicate an increase in muscle movement
EEG recordings decrease in amplitude and increase in frequency
EOG recordings indicate in increase in rapid eye movement
EEG recordings increase in amplitude and decrease in frequency
During this stage of sleep, you drift in and out of sleep and can be easily awakened
NREM Stage 1
NREM Stage 2
NREM Stage 3
All NREM stages
What type of data does an electroencephalography (EEG), electromyography (EMG) and electro-oculography (EOG) collect?
primary quantitative data
secondary qualitative data
secondary quantitative data
primary subjective data
Which statement provides the best evidence that this is a typical adult hypnogram?
REM sleep occurs at the beginning of each sleep cycle.
The individual enters NREM Stage 3 during every sleep cycle.
REM sleep occurs at the end of each sleep cycle and increases in duration across the night.
The individual wakes several times between each sleep cycle and has a sleep episode of ~7.5 hours
