Chapter 9 Review
PSYCH 335

1. Many of the measures taken of a subject during a night of sleep focus on

changes in the self-conscious during awake states
self-reports of dream states
the degree of tossing and turning during sleep
electrical activity of the muscles, skin, and brain

2. Delta waves, the largest, slowest EEG waves, predominate during

REM sleep
stage 2 sleep
initial stage 1 sleep
stage 4 sleep

3. The typical free-running period of a human sleep is

less than 24 hours
about 24 hours
exactly 24 hours
more than 24 hours

4. The presence of beta-wave activity in the EEG of an awake person implies that the person is

alert and attentive
is about to enter the first stage of sleep
drowsy
none of the above are correct

5. The REM phase of sleep is characterized by

an EEG that appears to be of an awake person
the presence of gross eye movements
a silent EMG record
all of the above are correct

6. The fact that organisms continue to sleep even under conditions in which sleeping behavior is dangerous suggests that

some organisms enjoy sleep even though such behavior may be maladaptive
sleep is critical for survival
sleep is just an adaptive behavior
sleep is a maladaptive behavior

7. The observations that delta activity is lowest during slow-wave sleep, and that sleep-deprivation produces cognitive problems on following days suggests that

REM sleep is critical for resting
the brain rests during slow-wave sleep
the brain is reorganizing its data files during slow-wave sleep
slow-wave sleep is critical for dream analysis

8. There are neurons in the caudal reticular formation that seem to play a role in inhibiting REM sleep. These are the

serotonergic neurons of the dorsal raphé nuclei
cholinergic neurons of the basal forebrain
cholinergic neurons of the pons reticular formation
both b and c

9. Which of the following is true of the relation between histamine and sleep?

the activity of histamine-containing neurons is high during waking
drugs that block histamine receptors increase sleep
the activity of histamine-containing neurons is low during slow-wave sleep and during REM sleep
histamine-containing cells only project to the spinal cord

10. Lesions of the raphé nuclei

increases arousal
inhibit the basal forebrain cells
increases sleep
inhibit the locus coeruleus
