Three experiments were conducted to examine whether timing processes can be shared by continuous tapping and drawing tasks. In all 3 experiments, temporal precision in tapping was not related to temporal precision in continuous drawing. There were modest correlations among the tapping tasks, and there were significant correlations among the drawing tasks. In Experiment 3, the function relating timing variance to the square of the observed movement duration for tapping was different from that for drawing. The conclusions drawn were that timing is not an ability to be shared by a variety of tasks but instead that the temporal qualities of skilled movement are the result of the specific processes necessary to produce a trajectory. These results are consistent with the idea that timing is an emergent property of movement.
进行了三项实验，以检验连续敲击和绘图任务是否可以共享计时过程。在所有三项实验中，敲击的时间精度与连续绘图的时间精度无关。敲击任务之间存在适度的相关性，绘图任务之间存在显著的相关性。在实验3中，敲击任务中计时方差与观察到的运动持续时间平方之间的函数关系与绘图任务不同。得出的结论是，计时不是一种可以被各种任务共享的能力，而是熟练运动的时间特性是产生轨迹所需的特定过程的结果。这些结果与计时是运动的一种涌现特性这一观点一致。
