Prominence of the brain's right-hemisphere information processing and intensity of dream experience are two theoretically related constructs that have been proposed as important psychological aspects of REM sleep. Either view is consistent with the prediction that the effect of REM deprivation will depend in part on the nature of cognitive activity that is initiated at the onset of each REM period and that "substitutes" for the interrupted REM process. In the present study, the effect of REM deprivation was more striking for female subjects given a digits task than for female subjects given a fantasy-reporting task during awakening used to induce REM deprivation for the first 6 hours of the night. High neuroticism appeared to exaggerate the effect. No corresponding pattern was observed for the male subjects. These preliminary finding may be exaggerated by cognitive activity that is functionally incongruent with those processes. The results also raise interesting questions about individual differences.
大脑右半球信息处理的突出性和梦境体验的强度是两个在理论上相关的概念，它们被认为是快速眼动睡眠重要的心理方面。这两种观点都与以下预测一致，即快速眼动睡眠剥夺的影响将部分取决于在每个快速眼动睡眠期开始时启动的认知活动的性质，以及该认知活动对被中断的快速眼动睡眠过程的“替代”作用。在本研究中，对于在夜间最初6小时用于诱导快速眼动睡眠剥夺的唤醒期间接受数字任务的女性受试者，快速眼动睡眠剥夺的影响比对接受幻想报告任务的女性受试者更为显著。高神经质似乎会夸大这种影响。在男性受试者中未观察到相应的模式。这些初步发现可能会因与那些过程功能不一致的认知活动而被夸大。研究结果还引发了关于个体差异的有趣问题。
