In four consecutive weekly sessions 12 subjects, aged 20--25 years, listened to a sentence stimulus before the onset of sleep and were asked to reproduce it after an awakening provoked during stage 2 or REM sleep of the first cycle. Recall of the sentence stimuli heard before sleep was affected by their semantic acceptability, but was unaffected by the sleep type (REM/NREM) or by the length of waking preceding sleep. The differing retention intervals involved for the recall tests after REM and NREM sleep may, however, have masked any effect of the former on recall.
在连续四周的每周一次的实验环节中，12名年龄在20至25岁之间的受试者在睡眠开始前聆听句子刺激，并被要求在第一个睡眠周期的快速眼动（REM）睡眠或第二阶段睡眠期间被唤醒后复述该句子。睡眠前听到的句子刺激的回忆受到其语义可接受性的影响，但不受睡眠类型（快速眼动睡眠/非快速眼动睡眠）或睡眠前清醒时间长度的影响。然而，快速眼动睡眠和非快速眼动睡眠后回忆测试所涉及的不同保留间隔可能掩盖了前者对回忆的任何影响。
