Abstract:
The goal was to examine the effect of changing knowledge-of-results bandwidth based on a participant's stable performance during acquisition of a timing skill. 36 university students experienced one of three conditions: (1) 100% KR condition during which information on errors was provided after each trial during practice, (2) fluctuation-of-range condition, wherein KR bandwidth was based on standard deviation of five trials, and (3) 10% KR bandwidth condition (10%), wherein the KR bandwidth was 810-990 msec. Variable error in the fluctuation-of-range condition at posttest and retention was significantly smaller than that with the 100% KR. Conditions in which range of KR was allowed to fluctuate were more effective for stabilizing performance.
