本文对64名智力低下者进行了自定步速与同步叩击的关系研究。智力低下者的年龄为2 ~ 11岁，实际年龄为13 ~ 23岁。在一个自定进度的敲击任务中，没有刺激，被试的轻松和自发的敲击uas测量。在同步敲击任务中，测量了它们与以快或慢克里思存在的听觉刺激的同步敲击。在两种克里思条件下，被试的心理年龄越大，他们在互拍间隔中所犯的错误越大。低智力年龄的受试者在慢节奏条件下的敲击间隔误差显著大于快克里思条件下的敲击间隔误差，并且倾向于以接近自步速敲击的速率敲击。这些结果可能表明，调整自己的速度的能力是一个关键因素的发展运动同步的精神发育迟滞的人。
The relation between self-paced and synchronized tapping in 64 persons with mental retardation whose mental ages ranged from 2 to 11 years and chronological ages from 13 to 23 years was investigated. In a self-paced tapping task no stimulus was presented, and subjects' easy and spontaneous tapping uas measured. In a synchronized tapping task their synchronous tapping with an auditory stimulus present at a quick or slow tempo was measured. Under both tempo conditions, thr lon er the subjects' mental age, the larger the errors in the intertap interval they made. The subjects of low mental age showed significantly larger errors in the intertap interval in thr Slow than in the Quick Tempo condition and tended to tap at a rate near the self-paced tapping. These results may suggest that ability to adjust one's self pace is one of the key factors in the development of motor synchronization in persons with mental retardation.
