手指序列学习需要视觉空间工作记忆（WM）。然而，年龄，工作记忆训练和运动技能获得之间的动态尚不清楚。因此，我们研究了视觉空间WM训练如何提高年轻人（n = 26，21.1 +/- 137岁）和老年人（n = 22，70.6 +/- 4.01岁）的手指运动顺序准确性。在完成手指序列学习练习和数字和空间WM任务后，每个年龄组的参与者被随机分配到实验组（EX）或控制组（CO）。在10天的时间里，EX组每天练习一个小时的自适应n-back空间任务，而CO组练习的是非自适应版本。作为WM实践的结果，EX参与者增加了他们的准确性在空间n-back任务，而准确性仍然没有改善在数字n-back任务。在所有组中，反应时间（RT）变得更短，在大多数数字和空间n-back任务。EX组的学习者在手指序列的保持方面有所改善，而CO组的学习者则没有。研究结果支持了我们的假设，即计算机化的视觉空间WM训练提高了年轻人和老年人的手指序列学习。我们讨论了这项研究的理论意义和临床意义的运动学习和功能康复。(C)2015 Elsevier B.

Finger sequence learning requires visuospatial working memory (WM). However, the dynamics between age, WM training, and motor skill acquisition are unclear. Therefore, we examined how visuospatial WM training improves finger movement sequential accuracy in younger (n = 26, 21.1 +/- 137 years) and older adults (n = 22, 70.6 +/- 4.01 years). After performing a finger sequence learning exercise and numerical and spatial WM tasks, participants in each age group were randomly assigned to either the experimental (EX) or control (CO) groups. For one hour daily over a 10-day period, the EX group practiced an adaptive n-back spatial task while those in the CO group practiced a non-adaptive version. As a result of WM practice, the EX participants increased their accuracy in the spatial n-back tasks, while accuracy remained unimproved in the numerical n-back tasks. In all groups, reaction times (RT) became shorter in most numerical and spatial n-back tasks. The learners in the EX group but not in the CO group showed improvements in their retention of finger sequences. The findings support our hypothesis that computerized visuospatial WM training improves finger sequence learning both in younger and in older adults. We discuss the theoretical implications and clinical relevance of this research for motor learning and functional rehabilitation. (C) 2015 Elsevier B.V. All rights reserved.
