Abstract
-
The aim of this study is to examine whether there are changes in sleep mentation following REM deprivation and the nature of these changes if they exist. This research takes into account what interactions there might be between physiology (i.e. phasic activity) and a particular mental "state" (i.e. the presence or absence of a self observing capacity). The prediction is that the presence of higher levels of internal stimulation (in the form of phasic activity) following RD will trigger greater immersion in one's mentation.;This study tested the hypothesis that as RD continues, NREM mentation will more and more resemble phasic REM mentation. It was also hypothesized that REM tonic mentation will resemble REM phasic mentation as RD proceeds across nights.;I analyzed the responses to RD on the second and third nights of a RD experiment in terms of changes in REM and NREM mentation following REM deprivation vs. NREM deprivation as measured by 5 scales which assess a subject's absorption in his dreaming process: the Absorption In Mentation Scale ("AIM")--(1) Reality Scale (2) Global Scale (3) Self Representation Scale; and the (4) Foulkes DF Scale, and (5) Molinari and Foulkes SCE/PVE Scale.;The data were analyzed by means of a three-way analyses of variance in which the independent variables were experimental night, REM condition and phasic condition.;The results showed that with respect to the effect of experimental night, a significant main effect was observed only on the AIM Self Representation Subscale. No significant effects due to REM deprivation were observed when absorption in mentation was measured by the DF scale or by the SCE/PVE scale.;The findings suggest that self-reflection may be relatively independent of other aspects of the dream experience. This, in turn, suggests that sleep mentation measures must differentiate among the various attributes of dreaming, including loss of self reflection, the sense of reality of the experience, and the vividness of the experience.
