Abstract
-
This study was an attempt to examine how personality variables measurable by self report inventories about a subject's daydreaming patterns and characteristic modes of handling anxiety relate to the subject's response to REM deprivation. Twenty male subjects slept in the laboratory for 2 baseline nights, 3 REM deprivation nights and 1 recovery night and returned to the lab 3-8 days later for 2 additional baseline nights, 3 NREM control deprivation nights and 1 recovery night. Subjects received the two conditions in counterbalanced order. Sleep records were scored for the amount of increase in REM time from baseline to recovery nights. Nine dreams per night were collected from each of the 20 subjects. Dreams were collected from either phasic (bursts of rapid eye movements--REMs) or tonic (no REMs) intervals of REM and NREM sleep. Dreams were scored by two raters blind to subject characteristics and awakening condition on 8 scales which measured a subject's absorption in his dreaming process. Subjects were scored on a variety of personality measures. They were divided on the median of their personality scores in order to assess differences amongst subject groups in their response to REM deprivation, both in terms of physiological compensation for lost REM sleep as well as changes in REM and NREM mentation. Dream scales were first analyzed on baseline nights so that scales which were good discriminators of phasic vs. tonic awakenings were chosen. It was predicted that only the scales that could discriminate phasic from tonic awakenings would be sensitive to changes following REM deprivation. No significant differences in subject groups were found in the amount of REM rebound following RD. All subjects showed an increase in the direction of greater involvement in their NREM mentation following RD, but did so only on scales which were better discriminators of phasic and tonic awakenings on baseline nights. There were individual differences in the patterns of REM mentation following REM deprivation such that subjects who tended to report or focus on anxiety producing thoughts did not show any changes following REM deprivation in their REM mentation. Subjects who tended to not report anxiety producing thoughts showed an enhancement of their perceived and rated absorption in their REM mentation on deprivation nights. They showed a decrease in the absorption in their REM mentation on recovery nights following REM deprivation, but not following NREM control deprivation. These results were shown only on scales which were good discriminators of phasic vs. tonic awakenings on baseline nights. Results were interpreted to mean that the patterning of phasic activation determines to some extent the corresponding dream mentation, but this is interfered with by a subject's mode of reporting anxiety producing thoughts. In addition, the project served to validate the ability of certain mentation scales as discriminators of phasic vs. tonic awakenings.
