Correlation Between Measures of the Rapid Eye Movements of Wakefulness and Sleep

ABSTRACT Literature review suggested that certain properties of the REMs of wakefulness and REM sleep show changes with experience and/or maturation. A positive correlation was predicted to obtain between measures of REM sleep intensity and waking information search organization/activity in normal human adults. A correlational study of the REMs of sleep and wakefulness in 9 college‐age Ss corroborated the hypothesis. Percentage REM sleep did not correlate significantly with any of the waking REM measures. Implications of the results for current theories and future research on REM sleep–waking perception interrelationships were described.
