Abstract: 本研究更改Sherwood(1996)的研究中有關測量錯誤偵察的設計,進一 步檢驗不同情境干擾程度對自我配速動作空間準確性及錯誤偵察能力學習的影響。 實驗參加者為三十二名女性,平均年齡20.9歲(標準差2.4歲),隨機分派 到集團/集團、集團/隨機、隨機/集團及隨機等四組中。實驗動作為 自我配速的線性直臂外移之後被動折返動作。經混合設計二因子變異數分析及 杜凱氏法事後比較,結果顯示在獲得期,集團組別的動作準確性(AE)及錯誤 偵察(│O-S│)能力的表現,高於隨機組別。在保留期,集團組別的動作 準確性衰退情形較隨機組別顯著,而在錯誤偵察方面則各組在立即保留期的衰 退情形皆達顯著。因此,在本研究的限制下結論是,相對高情境干擾的隨機練 習有助於動作準確性提昇,但對於動作錯誤偵察能力的提昇沒有顯著效果。
The purpose of this study was to investigate the contextual interference effects on the acquisition of spatial accuracy and error detection in a self-paced motor task. Thirty-two female participants made either 18,33,or 48 cm straight-arm outward and reversal movement in the limear movement device. Participants were randomly assigned to one of the following practice groups:(a) blocked /blocked groups (b) blocked/random group, (c) random/blocked groupm and (d) random/random group. Mixed ANOVA and Tukey's HSD method were utilized for analyses. During acquisition phase, blocked practice group resulted in less absolute error (AE) and absolute objective-subjective difference (│O-S│ )relative to the random group. On no-knowledge of result retention test, blocked practice group decreased significantly relative to the random group in terms of spatial accuracy; but no significant difference in error detection was found. Thus, within the limitation of this study, it was concluded that relative high in contextual interference, random practice, benefits of spatial accuracy but not of the capability of error detection.
