单和交替的手轻拍进行了比较，以测试的假设，协调在有节奏的运动是由特定的时间间隔的控制介导的。在实验1中，听觉节拍器被用来指示一组定时模式，其中1秒的间隔被分为2个子间隔。性能，从目标模式和变异性的偏差方面进行测量，是类似的条件下，其中手指轻敲用1只手或交替的2只手。在实验2中，模态的节拍器（听觉或视觉）被发现影响的方式，其中产生的间隔偏离目标模式。这些结果挑战的概念，双手协调出现耦合约束固有的2手系统。它们与强调控制特定时间间隔以形成一系列明确的运动事件的框架是雅阁的。
Single and alternating hand tapping were compared to test the hypothesis that coordination during rhythmic movements is mediated by the control of specific time intervals. In Experiment 1, an auditory metronome was used to indicate a set of timing patterns in which a 1-s interval was divided into 2 subintervals. Performance, measured in terms of the deviation from the target patterns and variability, was similar under conditions in which the finger taps were made with 1 hand or alternated between the 2 hands. In Experiment 2, the modality of the metronome (auditory or visual) was found to influence the manner in which the produced intervals deviated from the target patterns. These results challenge the notion that bimanual coordination emerges from coupling constraints intrinsic to the 2-hand system. They are in accord with a framework that emphasizes the control of specific time intervals to form a series of well-defined motor events.
