作者测试了一个简单的模型，该模型基于取消方位角的变化率，可以解释当个体在行走时拦截移动的球时产生的行为适应。在实验1中，球的到达地点和方法的角度是不同的。与该模型的雅阁一致，接近角越大，速度调节越早且越明显。在实验2中，球速在试验过程中意外地改变，再次突出了参与者的功能速度适应。每个单独的试验（N = 256）的基础上的模型的直接测试显示，平均而言，70%的总方差可以解释。总之，这些结果证实了这种鲁棒策略在控制拦截任务中的有用性。
The authors tested whether a simple model based on the cancellation of the rate of change in bearing angle could account for the behavioral adaptations produced when individuals intercept moving balls while walking. In Experiment 1, the place of arrival of the ball and the angle of approach were varied. In accord with the model, velocity regulations were earlier and more pronounced the larger the angle of approach. In Experiment 2, ball speed unexpectedly changed during a trial, once again highlighting participants' functional velocity adaptations. A direct test of the model on the basis of each individual trial (N = 256) revealed that, on average, 70% of the total variance could be explained. Together, those results confirm the usefulness of such a robust strategy in the control of interceptive tasks.
