How does the time of day of a practice session affect learning of a new motor sequence in the elderly? Participants practiced a given finger tapping sequence either during morning or evening hours. All participants robustly improved performance speed within the session concurrent with a reorganization of the tapping pattern of the sequence. However, evening-trained participants showed additional gains overnight and at 1 wk posttraining; moreover, evening training led to a further reorganization of the tapping pattern offline. A learning experience preceding nocturnal sleep can lead to a task-specific movement routine as an expression of novel "how to" knowledge in the elderly.
一天中的什么时段进行练习会影响老年人对新运动序列的学习？参与者在早上或晚上练习给定的手指敲击序列。所有参与者在练习过程中都显著提高了运动速度，同时对序列的敲击模式进行了重新组织。然而，晚上训练的参与者在夜间和训练后 1 周内仍有额外的提高；此外，晚上训练还导致敲击模式在离线状态下进一步重组。在夜间睡眠之前的学习经历可以导致特定于任务的运动常规，这是老年人新的“如何做”知识的表现。
