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).
对13名慢性原发性失眠症患者和一组相匹配的正常睡眠者进行了研究，涉及他们的猎奇水平、幻想能力和认知反刍。整夜脑电图模式证实了失眠症患者与对照组在睡眠方面的差异。慢性失眠症患者在作为一种防御模式的认知活动测量指标（伯恩的压抑-敏感量表）上与正常睡眠者不同，但在认知刺激需求测量指标（皮尔逊的内部和外部认知量表）、幻想能力（贝茨意象任务）或对幻想的偏好（皮尔逊的内部和外部感觉量表）上没有差异。
