The present paper provides some hypotheses concerning the role of sensorimotor mechanisms in the coordination and programming of multimovement behaviors. The primary database is from experiments on the control of speech, a motor behavior that inherently requires multimovement coordination. From these data, it appears that coordination may be implemented by calibrated, sensorimotor actions which couple multiple movements for the accomplishment of common functional goals. The data from speech and select observations in other motor systems also reveal that these sensorimotor linkages are task-dependent and may underlie the intermovement motor equivalence that characterizes many natural motor behaviors. In this context, it is hypothesized also that motor learning may involve the calibration of these intermovement sensorimotor actions. These observations in turn provide some alternative perspectives on the concept of a motor program, primarily suggesting that individual movements and muscle contractions are not wholly prespecified, but shaped by sensorimotor adjustments.
本文提出了一些关于感觉运动机制在多动作行为的协调与编程中所起作用的假说。主要数据库来自关于言语控制的实验，言语是一种本质上需要多动作协调的运动行为。从这些数据来看，协调可能是通过经过校准的感觉运动动作来实现的，这些动作将多个动作耦合起来以实现共同的功能目标。来自言语的数据以及在其他运动系统中的选定观察结果还表明，这些感觉运动联系是任务依赖的，并且可能是许多自然运动行为所具有的运动间等效性的基础。在此背景下，还假设运动学习可能涉及这些运动间感觉运动动作的校准。这些观察结果反过来为运动程序的概念提供了一些不同的观点，主要表明单个动作和肌肉收缩并非完全预先确定，而是由感觉运动调整塑造而成。
