漸增情境干擾練習下動作表現與學習不受自我控制影響

Abstract

本研究結合情境干擾與自我控制的概念，旨在探討漸增情境干擾練習的安排下，自我控制對動作表現與學習的影響。以24名年輕成人為實驗參與者，並隨機分派至漸增情境干擾練習自我控制組或漸增情境干擾練習自我控制對照組。實驗工作為三個由不同相對時宜比率所組成的N字型按鍵時宜動作，總動作時間均為1800毫秒。依變項為絕對誤差值、總變異值、與相對時宜誤差值，經2（組別）x 3（區間）混合設計二因子變異數分析，其中區間為重複量數，以及獨立樣本t考驗。結果發現：（一）在獲得期中，兩組的絕對誤差值、總變異值、相對時宜誤差值差異未達統計顯著水準；（二）在保留測驗中，兩組的絕對誤差值、總變異值、相對時宜誤差值差異未達統計顯著水準。依上述結果，本研究的結論為：（一）在漸增情境干擾的練習安排下，動作表現的準確性、穩定性與相對時宜準確性，不受自我控制的影響；（二）在漸增情境干擾的練習安排下，動作學習的準確性、穩定性與相對時宜準確性，不受自我控制的影響。

Concepts of contextual interference and self-control were combined in this study. Effects of self-control on motor performance and learning under gradual contextual interference practice scheduling were examined. Twenty four young adult participants were randomly assigned into gradual contextual interference practice of self-control group or yoked group. Three “N” shape tasks with different relative timing but with the same overall duration (1800 ms) were used as experimental task. The dependent variables were absolute error, total variability, and relative timing error. 2 (group) x 3 (block) mixed design two-way ANOVA with repeated measures on blocks and independent t test indicated (1) absolute error, total variability, and relative timing error, were found no significant difference in acquisition phase; (2) absolute error, total variability, and relative timing error, were found no significant difference in retention test. These findings suggested that (1) There is no effect of self-control in gradual contextual interference practice scheduling on motor performance of motor accuracy, motor stability, and relative timing; (2) There is no effect of self-control in gradual contextual interference practice scheduling on motor learning of motor accuracy, motor stability, and relative timing accuracy.
