Previous studies suggest that sleep may play an important role in memory consolidation of motor skills. It has been difficult, however, to tease apart the effect of sleep from circadian and homeostatic factors. We examined the effect of sleep on a popular motor sequence task, utilizing a design that controlled for time of day and time since sleep between wake and sleep groups. When these factors were controlled, there was no benefit of sleep to motor memory, suggesting that previous work may have been influenced by circadian and homeostatic confounds.
先前的研究表明，睡眠可能在运动技能的记忆巩固中发挥重要作用。然而，很难将睡眠的影响与昼夜节律和内稳态因素区分开来。我们利用一种设计，控制了清醒组和睡眠组之间的时间和自睡眠以来的时间，研究了睡眠对一项流行的运动序列任务的影响。当这些因素得到控制时，睡眠对运动记忆没有益处，这表明先前的研究可能受到了昼夜节律和内稳态混淆因素的影响。
