项目摘要

The purpose of this study was to examine the effect of learning strategy adopted by the learner on the motor learning. Concretely, the effectiveness of KR-use schedule adopted by the leaner was compared with the effectiveness of typical KR frequency conditions in the first experiment, and the effectiveness of practice schedule adopted by the learner was compared with the effectiveness of typical practice schedules in the second experiment.Slight different results were found between two experiment results. In the first experiment, subjects tended to adopt 100% KR use schedule, and this strategy was inconsistent with the recent findings that practice condition with 100% KR is inferior to the condition with less frequent KR condition. In the second experiment, almost all subject didn't adopt typical "block" schedule, and this result was not contradictory to the "contextual interference effects" found by the study of motor learning. Moreover, no subject adopted typical random practice strategy, and various types of practice schedule were found which were not the same as typical block or typical random practice schedule.In addition to the former two experiments, the whole body coordination strategy adopted by the learner in the learning of three motor tasks was also examined. In this experiment, it was hypothesized that one reason of the superiority of random practice schedule over block practice schedule might be the difference of whole body coordination resulted in the composition of practice schedule. Contrary to expectation, contextual interference effect was not found in the performance analysis, therefore the residual motion analysis was abandoned. However, interesting results were obtained concerning the change of coordination along with the practice.

本研究旨在考察学习者所采用的学习策略对动作学习的影响。具体而言，在第一次实验中，将学习者采用的KR-Use时刻表的有效性与典型KR频率条件下的有效性进行了比较；在第二次实验中，将学习者采用的练习时刻表的有效性与典型练习时刻表的有效性进行了比较，发现两个实验结果略有不同。在第一个实验中，被试倾向于采用100%KR使用程序，这一策略与最近的研究结果不一致，即100%KR的练习条件不如KR频率较低的条件。在第二个实验中，几乎所有被试都没有采用典型的“阻塞”程序，这一结果与运动学习研究中发现的“情境干扰效应”并不矛盾。此外，没有被试采用典型的随机练习策略，也没有发现不同于典型块或典型随机练习策略的各种类型的练习时间表。在本实验中，我们假设随机练习计划优于整体练习计划的原因之一可能是由于练习计划的整体协调性不同而导致的。与预期相反，在性能分析中没有发现情境干扰效应，因此放弃了剩余运动分析。然而，随着实践的进行，关于配位变化的研究取得了有趣的结果。
