最近有研究表明，选择性REM睡眠剥夺（selective REM sleep deprivation，REMD）会导致大学生在逻辑任务中应用规则的记忆受损，但对配对联想任务的回忆无影响。本实验的目的是检查总睡眠延迟（TSD）和（REMD）收购后的纯运动任务，追求转子的影响。在实验1中，受试者（N = 90）暴露于TSD的几个晚上训练后的一个。结果表明，在同一天晚上进行TSD训练，一周后的重测成绩较差。实验2中，受试者（N = 42）在任务获得当晚暴露于各种睡眠剥夺。一组接受REMD。其他组包括非REM觉醒对照组（NREMA）、TSD组、正常休息对照组和允许在夜间前4小时睡眠的组（LH-TSD）。结果显示，REMD组和对照组对这项任务有很好的记忆力，而TSD组和LH-TSD组对这项任务的记忆力明显较差。NREMA组表现出轻微但不显著的缺陷。结论是，第二阶段睡眠，而不是快速眼动睡眠是有效的记忆处理的追求转子任务的重要阶段的睡眠。
It has recently been reported that selective REM sleep deprivation (REMD) in college students results in memory impairment of the application of a set of rules in a logic task, but not recall of a paired associate task. The present experiments were designed to examine the effects of Total Sleep Deprivation (TSD) and (REMD) following acquisition of a pure motor task, the pursuit rotor. In Experiment 1, subjects (N = 90) were exposed to TSD for one of several nights following training. Results showed that TSD on the same night as training resulted in poorer performance on retest one week later. In Experiment 2, subjects (N = 42) were exposed to various kinds of sleep deprivation on the night of task acquisition. One group was subjected to REMD. Other groups included a non-REM awakening control group (NREMA), a TSD group, a normally rested Control group and a group allowed the first 4h of sleep in the night before being subjected to TSD (LH-TSD) for the rest of the night. Results showed the REMD and Control groups to have excellent memory for this task while the TSD and LH-TSD subjects had significantly poorer memory for the task. The NREMA group showed a slight, but not significant deficit. It was concluded that Stage 2 sleep, rather than REM sleep was the important stage of sleep for efficient memory processing of the pursuit rotor task.
