The effects of relative frequency of knowledge of results on the retention of a motor skill was studied. Adams' theory (1971) contends that the perceptual trace of a criterion position gains on increment of strenth each time the feedback stimuli associated with the criterion position are experienced and that it is the strength of the perceptual trace that determines retention. Schmidt's theory (1975), however, suggests that the recognition schema is updated only on trials on which the feedback stimuli associated with the criterion position are experienced in conjunction with knowledge of results and that it is the precision of the recognition schema that determines retention. Two experiments were conducted. The results provided evidence contrary to Adams' theory. Schmidt's theory, however, was only partially supported.
研究了结果知识的相对频率对运动技能保持的影响。亚当斯的理论（1971年）认为，每当体验到与标准位置相关的反馈刺激时，标准位置的知觉痕迹强度就会增加，并且是知觉痕迹的强度决定保持。然而，施密特的理论（1975年）表明，只有在与标准位置相关的反馈刺激与结果知识一起被体验的试验中，识别图式才会更新，并且是识别图式的精确性决定保持。进行了两项实验。结果提供了与亚当斯理论相反的证据。然而，施密特的理论仅得到部分支持。
