Dement & Kleitman - ANSWERS-(sleep and dreams)
Biological
Laboratory
Dement & Kleitman Background - ANSWERS-Sleep and dreaming are
hard to study because the participants are unresponsive; therefore
physiological measures are needed. Prior to this study psychologists
didn't know how to measure dreams, but a study by Aserinsky and
Kleitman in 1955 showed that we experience several REM and nREM
stages during the night. During REM sleep subjects recorded more
dream activity than in nREM sleep. Using an EEG machine, brain
activity and eye movement could be measured objectively.
Dement & Kleitman Aims: - ANSWERS-Find out more about dreaming:
Does dream recall differ between eye movement (REM) and quiescent
(nREM) stages of sleep?
Is there a positive correlation between the subjective estimates of dream
duration and the length of the REM period before waking?

EXAM QUESTIONS AND
ANSWERS 2026 - 2027
Are eye movement patterns related to dream content?
Dement & Kleitman: Sample - ANSWERS--7 males and two female
adults
-5 were studied, 4 used to confirm results
Dement & Kleitman: Experimental Design: - ANSWERS-Test
One:Repeated Measures (multiple sleep sessions)
Test Two: Correlation (Repeated Measures)
Test Three: Self Report compared to observed eye movements
Dement & Kleitman Controls: - ANSWERS--no caffeine or alcohol
-sufficiently loud waking doorbell
-experimenter only asked question after participant complete recording
-Reports not counted as dreams if participant couldn't remember content
or vaguely remembered
