本文对29名3 ~ 6岁学龄前儿童的节奏动作的调节与自我步速反应进行了研究。听觉脉冲条件以听觉方式呈现脉冲，视觉脉冲条件以视觉方式呈现脉冲，而移动视觉目标条件呈现视觉目标的重复移动。我们使用了快速克里思节奏条件，其中刺激间隔与每个受试者感到舒适的平均自步速敲击率略有不同，而慢速克里思节奏条件中的间隔有很大不同。敲击的相互响应间隔中的误差，即，计算平均反应间和刺激间间隔之间的时间间隔作为调节的指标。只有在慢克里思条件下，前者的错误在各年龄组之间才有所减少。在慢节奏视觉脉冲条件下，反应间期的误差特别大，年轻的受试者倾向于以接近自我调节反应的速度反应。在这两种节奏中，在运动视觉目标条件下的反应间期的误差与听觉脉冲条件下的误差基本相同，并且在统计学上小于视觉脉冲条件下的误差。这些结果可能表明，在学龄前儿童的发展与物理节奏的同步的一个重要因素是能够修改或抑制的自我节奏的反应和额外的信息，从运动的视觉目标可以帮助他们在外部调节运动。
Regulation of the rhythmic movement of 29 preschoolers ages 3 to 6 years was studied in connection with self-paced response. An Auditory Pulse condition presented the pulse audibly, a Visual Pulse condition presented the pulse visibly, and a Moving Visual Target condition presented the repetitive movement of a visual target. We used a Quick Tempo condition in which the interstimulus interval was slightly different from the average self-paced tapping rate at which each subject felt comfortable, and a Slow Tempo in which the interval was considerably different. The error in the interresponse interval of tapping, i.e., the lime gap between the mean interresponse and interstimulus intervals, was calculated as an indicator of regulation. The error in the former decreased across age groups only in the Slow Tempo condition. In the Slow-Tempo Visual-Pulse condition in which the error in the interresponse interval was particularly large, the younger subjects tended to respond al a rate near the self-paced response. In both tempos, the error in the interresponse interval in the Moving Visual Target condition was much the same as in the Auditory Pulse condition and was statistically smaller than in the Visual Pulse condition. These results may suggest that one of the important factors in the development of preschoolers' synchronization with physical rhythm is an ability to modify or restrain the self-paced response and that additional information from movement of the visual target could assist them externally in regulating movement.
