The purpose of this study was to investigate the effects of extrinsic feedback(KR)of frequency and precision in dart throwing as practise goes on.
subjects were 64 university students and were randomly assigned in each experimental manipulated group. the experimental task was the dart throwing to target which was set 3m away from subjects. the group were 50% relative frequency group, 100% relative frequency group, self-controlled group and controlled. the precision of each group was devided into Qualitative KR, Quantitative KR.
Data was obtained from all subjects in five acquisition and two retention trials blocks. Analysis performed on acquisition trials were a 7×5(group×trial blocks) ANOVA with repeated measures, and then the retention trials were Analyzed a 7×2((group×trial blocks) ANOVA with repeated measures. And alpha was set 5%. The conclusion are as follows;
first, 100% relative frequency group shows the highest performance effect during acquisition and retention period in Qualitative KR group.
second, Quantitative KR shows higher performance effect than another groups in 50% relative frequency group, 100% relative frequency group and self-controlled group.
third, Quantitative 50% relative group shows the highest performance score, self-controlled group shows optimal performance curve.
