本研究旨在探討「不同精確程度的特定範圍結果獲知」，對初學者學習空間性動作與其錯誤偵察能力發展之影響。以32名先前沒有高爾夫球推桿動入經驗的大學在學女生為實驗參加者，隨機分成(1)範圍內KR組;(2)範圍內及誤差方向KR組;(3)範圍內量的KR組;(4)傳統BWKR組等四組。 實驗期間共計進行160次試做，包括前測均質性考驗的試做20次，獲得期的100次練習試做，以及十分鐘與隔天所進行的立即、延遲保留測驗各20次。本研究除了以參加者的動作表現為依變項外，也對參加者施以訪談， 藉以進一步剖析其內在認知對回饋所產生的觀感。在實驗中所測得的資料，先轉換成依變項的分數(正確試作比率、絕對誤差、變異誤差、客觀表現與主觀估計差異之絕對值)，再分別以二因子混合設計變異數分析、杜凱氏事後比較法與統計法，進行統計考驗。結果發現：(一)提供不同精確程度的特定範圍內結果獲知不會影響參加者動作穩定度的發展；(二)提供包含質的KR與量的KR,組合之特定範圍結果獲知，對學習者動作準確性之學習較有助益。其中，提供「範圍內量的 KR配合範圍外質的KR」與提供「範圍內質的KR配合範圍外量的KR」， 皆產生較好的動作準確性;和(三)不同精確程度的特定範圍內結果獲知會影響參加者錯誤偵察能力的發展。其中，提供範圍內結果獲知對參加者錯誤偵察能力的發展，有正面性的影響。

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.
