| Summary: | 碩士 === 國立師範大學 === 體育學系 === 86 === The purpose of this study was to investigate the effects of precision of knowledgeof results within bandwidth on learning a spatial motor task and its development of error detection capability. Thirty-two university female students who had no previous golf putting experience served as participants and were randomly assigned to one of following groups:(1)within BWKR group;(2)within BW and error direction of KR group;(3)within BW and error magnitude of KR group; and (4)tranditional BWKR group.Experimental trials for pretest to test the homogeneity of participants, 100practice trials for acquisition, 20 trials for 10-minute immediate retention test,and 20 trials for one-day delay retention test. Other than measuring participants'''''''' performance during acquistion and retention phases, on interviewing participants''''''''perception of feedback information was also administered. The error(AE), vaiableerror(VE), and absolute difference between objective performance and subjective estimation(|O-S|). Two-way ANOVA with one factor repeated, Tukey''''''''s HSD method and test were used for statistical analysis. Findings were as followings:(1)different percision KR within bandwidth did not affect movement consistency; (2)BWKR in combination of both qualitative KR and qualitative KR was found beneficial for participants'''''''' movement accuracy. Both groups which were provided" qualitative KRwithin BW associated with qualitative KR outside BW" produced participants'''''''' development of error detection capability. Among it, providing qualitative within BW" had positive effects on participants'''''''' development of error detection capability.
