Development in the way the hand approaches and intercepts a moving target was studied with children aged 6–11 years. The speed and trajectory of the target was varied. Hand movement was analysed in terms of: the speed and direction of the initial part of the response; ongoing modifications to the speed and path of movement; the speed and accuracy of the hand when close to the target. Results showed that the speed with which the hand moved initially was planned specifically for the target's speed and trajectory, while the direction of movement was planned only roughly. During the movement, there was usually only one adjustment to the speed of the hand, but frequent adjustments to the path of movement. The data show there are two important stages in the development of reaching to targets of different speed. By 8 years there is an advance in ability to plan a movement, while at 10 years there is development in ability to control the ongoing movemen
