Research suggests that sleep plays a vital role in memory. We tested the impact of total sleep deprivation on adults' memory for a newly learned writing system and on their ability to generalise this knowledge to read untrained novel words. We trained participants to read fictitious words printed in a novel artificial orthography, while depriving them of sleep the night after learning (Experiment 1) or the night before learning (Experiment 2). Following two nights of recovery sleep, and again 10 days later, participants were tested on trained words and untrained words, and performance was compared to control groups who had not undergone sleep deprivation. Participants showed a high degree of accuracy in learning the trained words and in generalising their knowledge to untrained words. There was little evidence of impact of sleep deprivation on memory or generalisation. These data support emerging theories which suggest sleep-associated memory consolidation can be accelerated or entirely bypassed under certain conditions, and that such conditions also facilitate generalisation.
研究表明，睡眠在记忆中起着至关重要的作用。我们测试了完全睡眠剥夺对成年人对新学书写系统的记忆以及将此知识推广到阅读未训练的新单词能力的影响。我们训练参与者阅读用一种新的人工拼写法印刷的虚构单词，同时在学习后的当晚（实验1）或学习前的当晚（实验2）剥夺他们的睡眠。经过两晚的恢复性睡眠后，以及在10天后再次进行测试，让参与者对训练过的单词和未训练的单词进行测试，并将其表现与未经历睡眠剥夺的对照组进行比较。参与者在学习训练过的单词以及将知识推广到未训练的单词方面表现出高度的准确性。几乎没有证据表明睡眠剥夺对记忆或推广有影响。这些数据支持了新出现的理论，这些理论表明，在某些条件下，与睡眠相关的记忆巩固可以加速或完全绕过，并且这些条件也有助于推广。
