Motor coordination has been too poorly defined to be a useful construct in studying the control of movement. In general, motor coordination involves controlling both the timing and the kinematics of movement. Yet the motor behaviors typically used for the study of coordination have required controlling only the timing or the spatial aspects of a movement. To understand better the basis of motor behavior, this study examined movement sequences, a class of movement in which both the timing and the kinematics must be controlled. In one experiment we studied a reaching and grasping movement sequence to characterize the central coordination of movement sequences. In another experiment we studied a throwing movement sequence to characterize the peripheral (kinesthetic) coordination of movement sequences. An heuristic model is presented to explain how central and peripheral mechanisms of coordination might interact to produce accurate movement.
运动协调的定义一直过于模糊，以至于在研究运动控制时难以成为一个有用的概念。一般来说，运动协调涉及控制运动的时间和运动学。然而，通常用于研究协调的运动行为只需要控制运动的时间或空间方面。为了更好地理解运动行为的基础，本研究考察了运动序列，这是一类必须同时控制时间和运动学的运动。在一个实验中，我们研究了一个伸手抓握的运动序列，以表征运动序列的中枢协调。在另一个实验中，我们研究了一个投掷运动序列，以表征运动序列的外周（动觉）协调。本文提出了一个启发式模型，以解释协调的中枢和外周机制如何相互作用以产生精确的运动。
