尽管有证据表明睡眠可以促进记忆，但有争议的发现涉及睡眠状态(NREM，REM)的作用。我们提出的假设是，睡眠组织，即NREM-REM周期的规律性发生，可能比睡眠状态本身更重要，可能对睡前呈现的言语材料的保持至关重要。实验要求年轻受试者在三种不同的夜间睡眠后回忆言语材料：无干扰睡眠、无睡眠周期紊乱的零碎睡眠和有睡眠紊乱的零碎睡眠。在睡眠周期被扰乱的夜晚之后，早晨对言语材料的回忆受到损害，而在睡眠周期被保留的夜晚之后，语言材料的早晨回忆能力受到损害；两种情况下的快速眼动的数量相似。我们的结论是，睡眠周期的紊乱对言语材料的回忆有很大影响。(C)2000 Elsevier Science B.V.保留所有权利。
Despite the evidence that sleep may facilitate memory, controversial findings concern the role of sleep states (NREM, REM). We put forward the hypothesis that sleep organization, i.e, the regular occurrence of NREM-REM cycles, more than sleep states per se, may be crucial for the retention of Verbal material presented before sleep. An experiment was performed in which recall of verbal material was requested of young subjects after three different kinds of night sleep: undisturbed sleep, fragmented sleep without sleep cycles disorganization, and fragmented sleep interrupted with sleep disorganization. Morning recall of verbal material was impaired after the night with disturbed sleep cycles, whereas it was not after the night with preserved sleep cycles; the amount of REM was similar in both cases. We conclude that the recall of verbal material is greatly affected by sleep cycle disorganization. (C) 2000 Elsevier Science B.V. All rights reserved.
