The primary purpose of this study was to examine the effects of dynamic acquisition protocols by comparing dynamic and static KR schedules in a single experiment. Five groups of participants (n = 13 per group) completed 90 acquisition trials of a force production task. The analysis of delayed no-KR retention test revealed that the participants in the summary fading KR group performed better than the three static KR groups, indicating that the dynamic acquisition protocols produces more efficient learning than static acquisition protocols. This finding is interpreted as support for Adams' theory (1971) that the most appropriate acquisition protocol would be one that dynamically manipulates KR from higher frequency at beginning to lower frequency toward the end of the practice. However, the failure in finding the learning effect of reduced KR in this experiment is inconsistent with the conclusion of the previous studies (Guadagnoli et al., 1996, Winstein & Schmidt, 1990). The reasons for this discrepancy are discussed and the future directions are provided.
