The present study involved three motor learning experiments; Experiments 1 and 2 measured regulating grasping power and isometric elbow flexion power, respectively. Knowledge of Results (KR) was given after completion of a task of short duration. Experiment 3 was similar to Experiment 2, but procedurally, KR was given concurrently with the task. Accordingly, KR processing takes place within the intertrial interval and parallel to taking task in Experiments 2 and 3, respectively. In these experiments, influences of varying intertrial intervals on the learning process were examined. The results were as follows; 1) In Experiments 1 and 2, shortening of the intertrial interval caused a delay in learning, however this was not the case for Experiment 3. Insufficient KR processing time is considered to be partially responsible for the above delay, 2) In Experiment 3, lengthening of the intertrial interval caused the above delay. These results suggest motor information processing to involve a property of natural decay with the course of time.
本研究包含三项运动学习实验；实验1和实验2分别测量了调节抓握力和等长屈肘力。在完成短时长任务后给出结果反馈（KR）。实验3与实验2相似，但在程序上，KR是与任务同时给出的。因此，在实验2和实验3中，结果反馈处理分别在试次间隔内进行且与执行任务并行。在这些实验中，研究了不同试次间隔对学习过程的影响。结果如下：1）在实验1和实验2中，试次间隔缩短导致学习延迟，然而实验3并非如此。上述延迟部分原因被认为是结果反馈处理时间不足，2）在实验3中，试次间隔延长导致了上述延迟。这些结果表明运动信息处理具有随时间自然衰减的特性。
