手眼协调进行了研究，在5-，7-，9-，和11岁的儿童，以测试的假设，在达到运动的编程系统和指导系统之间的关系的演变。在第一个实验中，孩子们必须进行开环运动（即，而不会尽可能准确地看到他们的手朝向视觉目标。实验二分析了戴有位移棱镜的儿童手的伸展轨迹，以测量轨迹的视觉引导部分。结果表明，开环伸展运动的时空特征和视觉引导活动量都存在明显的差异。一个优势的编程系统在5年和指导系统在7年，然后在9 - 11年的两个系统的集成，进行了讨论。
Hand-eye coordination was studied in 5-, 7-, 9-, and 11-yr-old children in order to test the hypothesis of an evolution in the relationship between the programming system and the guidance system in reaching movement. In the first experiment children had to perform open-loop movements (i.e., without seeing their hands towards visual targets as accurately as possible. The accuracy, time, speed, and patterns of movements were analyze second experiment the reach trajectories of the hand were analyzed in children wearing displacing prisms in order to measure the visually guided part of the trajectory. Charges in the spatial-temporal characteristics of open-loop reaching movements and in the amount of visual guided activity appear from the results. A predominance the programming system at 5 yr and guiding system at 7 yr, followed at 9 11 yr by integration of both systems, is discussed.
