To investigate human motor programming, choice reaction times were measured on tasks for which subjects made choices between two alternative finger-tapping-movement sequences. The total-number-of-responses and the hierarchical editor models were tested. In Exp. 1 the choice was carried on the situations with the same total numbers of possible responses and different structural relations between alternative sequences. The right-hand reaction times in mirror choice (e.g., subject chose between the middle, index, and ring finger sequences of the left or right hand) were shorter than those in nonmirror choice (e.g., subject chose between the middle, index, and ring finger sequence on one hand and the middle, ring, and index finger sequence on the other hand); the total-number-of-responses model was not supported. In Exp. 2 two conditions had the same operation numbers of the hierarchical editor model. In Condition 1 subjects chose between the index finger of the right hand and the ring, index, and middle finger sequence of the left hand. In Condition 2 subjects chose between the index, ring, and middle finger sequences of the left right hand. The reaction time in the former condition was shorter than that in the latter condition. Exp. 2 exhibited a counterexample of the hierarchical editor model that had been fairly robust in previous studies.
为了研究人类运动编程，在受试者对两种不同的手指敲击运动序列进行选择的任务中测量了选择反应时间。对总反应数模型和分层编辑器模型进行了测试。在实验1中，选择是在具有相同总反应数但备选序列之间结构关系不同的情况下进行的。镜像选择（例如，受试者在左手或右手的中指、食指和无名指序列之间进行选择）中的右手反应时间比非镜像选择（例如，受试者在一只手的中指、食指和无名指序列与另一只手的中指、无名指和食指序列之间进行选择）中的反应时间短；总反应数模型未得到支持。在实验2中，两种条件下分层编辑器模型的操作数相同。在条件1中，受试者在右手食指与左手无名指、食指和中指序列之间进行选择。在条件2中，受试者在左手或右手的食指、无名指和中指序列之间进行选择。前一种条件下的反应时间比后一种条件下的反应时间短。实验2展示了分层编辑器模型的一个反例，该模型在先前的研究中一直相当可靠。
