自我控制回饋對動作表現、學習及錯誤估計的效應

This study examined the effects of self-determined and-controlled feedback information on spatial motor performance, and learning and error detection capability. Thirty adults (16 males and 14 females) served as participants (mean age=22.5±2.1 years.). All participants were randomly assigned to (1) the self-controlled feedback group, (2) the yoked group, or (3) the control group. In the acquisition phase participants practiced 80 trails. After 24 hours participants were given 12 trials of the retention test. Self-paced movenment in the linear positioning was served as a task. Dependent variables were accuracy, stability and error detection capability. The one-way ANOVA and the Tukey method indicated first that the self-controlled group and the yoked group had significantly less variable error than that of the control group in acquisition phases (p＜.05, ES=0.68). The self-controlled group and the yoked group had significantly less variable error than that of those controlled in the retention test (p＜.05, ES=0.48). Second, the self-controlled group and the yoked group had significantly less absolute error than that of the control group in the acquisition phase (p＜.05, ES=0.71). The self-controlled group had less absolute error than that of the yoked group and the control group in the retention test (p＜.05, ES=0.70). Third, the self-controlled group and the yoked group had significantly less error detection's error than that of the control group in the acquisition phase (p＜.05, ES=0.71). The self-controlled group had less error detection's error than that of the yoked group and the control group in the retention test (p＜.05, ES=0.85). It was concluded that the self-controlled feedback is not the performance variable but the learning variable, and the self-controlled feedback benefits error detection capability.
