可靠的感觉-运动集成是实现最佳运动控制的先决条件;这种集成的功能在开发过程中会发生变化。此前的研究表明，学龄儿童的运动表现具有较高的变异性，特别是在视觉不可用的条件下，并且运动规划和控制很大程度上基于动觉输入。本研究的目的是确定在发展过程中，动觉-运动内部表征与视觉-运动表征如何相互作用的特点。为此，我们在59名5至12岁的儿童以及一组成年人中诱导了视觉运动适应，并在随后的视觉反馈不可用的条件下测量了初始方向误差（IDE）和终点误差（EPE），参与者必须依赖动觉输入。我们的研究结果表明，年龄较大的儿童（年龄范围9-12岁）去适应显着超过36个试验过程中，在视觉的情况下，年龄较小的儿童（年龄范围5-8岁），这表明，在年龄较大的儿童的动觉-运动的内部表示更有效地利用，以指导手的动作，并与成人的性能。
Reliable sensory-motor integration is a pre-requisite for optimal movement control; the functionality of this integration changes during development. Previous research has shown that motor performance of school-age children is characterized by higher variability, particularly under conditions where vision is not available, and movement planning and control is largely based on kinesthetic input. The purpose of the current study was to determine the characteristics of how kinesthetic-motor internal representations interact with visuo-motor representations during development. To this end, we induced a visuo-motor adaptation in 59 children, ranging from 5 to 12 years of age, as well as in a group of adults, and measured initial directional error (IDE) and endpoint error (EPE) during a subsequent condition where visual feedback was not available, and participants had to rely on kinesthetic input. Our results show that older children (age range 9–12 years) de-adapted significantly more than younger children (age range 5–8 years) over the course of 36 trials in the absence of vision, suggesting that the kinesthetic-motor internal representation in the older children was utilized more efficiently to guide hand movements, and was comparable to the performance of the adults.
