The purpose of this study is to prove that Post-KR delay interval is one of the variables in motor learning. It also aims at showing how the intervals vary according to different age groups. Theories of information processing and forgetting are disscussed with the assumption that longer the Post-KR delay interval is, the better peformance subjects show when dealing with simple tasks. Three groups, each comprising 30 subjects of age 7, 11, and adults were given curvilinear repositoning task, under 3 different time sequences of 3, 10, and 20 seconds. The three-way ANOVA with repeated measures conducted in the acquisition phase showed a significant difference in terms of age groups, temporal conditions, and blocks. The two-way ANOVA conducted in the transfer phase resulted in a significant difference among different age groups. Extended Post-KR interval brought about poor learning. This can be attributed to the character of the task, which indicates that theories of information processing and forgetting, specially their attributory interpretations can not be applied in the task of simple tasks.
