The present study investigated whether the initial impulse of goal-directed movements was visually monitored by 5- to 12-years-old children (n = 36) in a manner similar to adults (n = 12). The participants moved a cursor toward a fixed target. In some trials, the cursor was unpredictably translated by 20 mm following movement initiation. The results showed that even the youngest children visually monitor the initial impulse of goal-directed movements. This monitoring and the error correction process that it triggers seem automatic because it occurs even when the cursor jump is not consciously detected. Finally, it appears that this process does not fully mature before late childhood, which suggests that a putative dedicated channel for processing visual hand information develops during childhood.
本研究调查了5至12岁儿童（n = 36）是否会像成年人（n = 12）一样，对目标导向运动的初始冲动进行视觉监测。参与者将光标移向一个固定目标。在一些试验中，光标在运动开始后会不可预测地平移20毫米。结果表明，即使是最小的儿童也会对目标导向运动的初始冲动进行视觉监测。这种监测及其触发的错误纠正过程似乎是自动的，因为即使光标跳跃未被有意识地察觉，该过程也会发生。最后，似乎这个过程在童年晚期之前并未完全成熟，这表明在儿童时期会形成一个用于处理视觉手部信息的假定专用通道。
