Are movement sequences executed in a hierarchically controlled fashion? We first state explicitly what such control would entail, and we observe that if a movement sequence is planned hierarchically, that does not imply that its execution is hierarchical. To find evidence for hierarchically controlled execution, we require subjects to perform memorized sequences of finger responses like those used in playing the piano. The error data we obtain are consistent with a hierarchical planning as well as execution model, but the interresponse-time data provide strong support for a hierarchical execution model. We consider three alternatives to the hierarchical execution model and reject them. We also consider the implications of our results for the role of timing in motor programs, the characteristics of motor buffers, and the relations between memory for symbolic and motor information.
运动序列是以层次控制的方式执行的吗？我们首先明确说明这种控制将涉及哪些方面，并且我们观察到，如果一个运动序列是按层次进行规划的，这并不意味着它的执行也是层次化的。为了找到层次控制执行的证据，我们要求受试者执行记忆中的手指反应序列，就像弹钢琴时使用的那些序列一样。我们获得的错误数据与层次规划以及执行模型一致，但反应间时间数据为层次执行模型提供了有力支持。我们考虑了层次执行模型的三种替代方案并将其排除。我们还考虑了我们的结果对运动程序中时间安排的作用、运动缓冲区的特征以及符号信息记忆与运动信息记忆之间关系的影响。
