The aim of this study was to explore the differences in procedural learning abilities between children with DCD and typically developing children by investigating the steps that lead to skill automatization (i.e., the stages of fast learning, consolidation, and slow learning). Transfer of the skill to a new situation was also assessed. We tested 34 children aged 6-12 years with and without DCD on a perceptuomotor adaptation task, a form of procedural learning that is thought to involve the cerebellum and the basal ganglia (regions whose impairment has been associated with DCD) but also other brain areas including frontal regions. The results showed similar rates of learning, consolidation, and transfer in DCD and control children. However, the DCD children's performance remained slower than that of controls throughout the procedural task and they reached a lower asymptotic performance level; the difficulties observed at the outset did not diminish with practice.
本研究的目的是通过调查导致技能自动化的步骤(即快速学习、巩固和缓慢学习阶段),探索发育性协调障碍(DCD)儿童与发育正常儿童在程序性学习能力上的差异。还评估了技能向新情境的迁移情况。我们对34名6至12岁有或无DCD的儿童进行了感知运动适应任务测试,这是一种程序性学习形式,被认为涉及小脑和基底神经节(其损伤与DCD有关的区域),但也涉及包括额叶区域在内的其他脑区。结果显示,DCD儿童和对照组儿童在学习、巩固和迁移方面的速率相似。然而,在整个程序性任务中,DCD儿童的表现仍比对照组儿童慢,并且他们达到的渐近表现水平较低;一开始观察到的困难并没有随着练习而减少。
