In the light of the intensity coupling effects reported in the literature, subjects' capacities for independently controlling the absolute velocity of their movement at the point of interception was evaluated by asking them to learn to propel orthogonally approaching balls, varying in their speed of approach, into target boxes placed at various distances from the interception point. As required for successful accomplishment of the task, movement velocity was found to be adapted to the distance to be covered, with the near target giving rise to lower velocities and the far target giving rise to higher velocities even when the conditions were presented in random order. Nevertheless, even though target distance accounted for a substantial proportion of the total variance, a small but significant effect of ball approach speed on movement velocity was found, suggesting that intensity coupling is a persistent but modulable phenomenon in interception tasks.
根据文献中报道的强度耦合效应，通过要求受试者学习将以不同接近速度正交接近的球推进到与拦截点距离不同的目标箱中，来评估他们在拦截点独立控制其运动绝对速度的能力。正如成功完成任务所要求的那样，发现运动速度会根据要覆盖的距离进行调整，即使条件以随机顺序呈现，近目标产生的速度较低，远目标产生的速度较高。然而，尽管目标距离占总方差的很大比例，但发现球的接近速度对运动速度有微小但显著的影响，这表明强度耦合在拦截任务中是一种持续但可调节的现象。
