The periods of rhythmic stimuli and their corresponding responses play a dominant role in the planning and execution of motor events. Evidence for this comes from several sources. The fact that a constraint on the response period (as provided by the stimulus period) results in a well-defined optimization problem allows for a mathematical analysis that results in the complete specification of the three-dimensional coordinates of an upper-extremity movement trajectory. Thus, the result of study 1, in which mid-arc position variability is decreased, is a natural outcome of the response period constraint provided by the metronome.
