  • Title: Novelty-seeking, fantasy, and sensitization in chronic insomniacs.
    Author: Coursey RD, Frankel BL.
    Journal: Percept Mot Skills; 1977 Jun; 44(3 Pt 1):795-8. PubMed ID: 876789.
    Abstract:
    13 chronic primary insomniacs and a matched group of normal sleepers were studied in terms of their level of novelty-seeking, ability to fantasize, and cognitive rumination. All-night electroencephalographic patterns confirmed insomniac-control sleep differences. Chronic insomniacs differed from normal sleepers on a measure of cognitive activity as a defense pattern (Byrne's Repression-Sensitization Scale) but did not differ on measures of need for cognitive stimulation (Pearson's Internal and External Cognition Scales), ability to fantasize (Betts' imagery task), or preference for fantasy (Pearson's Internal and External Sensation Scales).
