When hitting a target that is moving, the time for planning the interception is limited. Instead of waiting for all the necessary information about the target's position and speed before starting to move, subjects could use their previous experience with similar targets to make initial guesses and adjust as new information becomes available. In the present study we examined whether the speed of the preceding target influences a hitting movement. Subjects hit moving targets that appeared on a screen about 40 cm in front of them. The targets moved at 6, 12 or 18 cm/s. Both the hand's initial movement direction and the final hitting error depended on the speed of the preceding target. We conclude that people control the way they hit moving targets on the basis of the speed of the preceding target.
当击打一个移动的目标时，用于规划拦截的时间是有限的。在开始移动之前，受试者不是等待关于目标位置和速度的所有必要信息，而是可以利用他们之前对类似目标的经验进行初步猜测，并在新信息可用时进行调整。在本研究中，我们研究了前一个目标的速度是否会影响击打动作。受试者击打出现在他们前方约40厘米屏幕上的移动目标。目标的移动速度为6、12或18厘米/秒。手部的初始移动方向和最终击打误差都取决于前一个目标的速度。我们得出结论，人们根据前一个目标的速度来控制他们击打移动目标的方式。
