摘要

目的：瞭解不同技術層次排球選手在預測舉球動作上之誤判差異。方法：以二所大學排球運動績優生及初級班學生共137名為參與者，依其對2000年奧運男子排球冠亞軍比賽中舉球動作之判斷，來測試其誤判情形，資料以廣義線性混合效應模型來分析。結果：一、2號位舉球動作於碰球後時，一般生比運動績優生顯著地較易誤判為3、4號位舉球動作；3號位舉球動作於碰球前與後時，一般生比運動績優生顯著地較易誤判為4號位舉球動作；4號位舉球動作於碰球前、中、後時，一般生比運動績優生顯著地較易誤判為3號位舉球動作。二、3、4號位舉球動作於碰球後時，運動績優生比一般生顯著地較易誤判為2號位舉球動作。結論：一、在2、3號位舉球動作的後期階段，因初學者較無法預測手臂或手指的舉球動作，故以4號位舉球動作的身體假動作作為預測前線索，誘導初學者較易誤判為4號位舉球動作。二、在3號位舉球動作的後期階段，因熟練者較能以手臂或手指作為預測前線索，其上舉動作誘導熟練者顯著地較易誤判為2號位舉球動作。

Purpose: To understand difference of wrong judgment of setting up movement prediction from volleyball players of different skill levels. Method: The study was designed to test wrong judgment conditions of total 137 students with high athletic performance and basic skills from two universities based on their judgment of setting up movements from film of male volleyball championship of 2000 Olympic Games. The data gained was statistically analyzed in Generalized Linear Mixed Effects Model. Results: A. After touching the ball in position 2 of setting up movement, students with basic skills were significantly more prone to judge wrongly as positions 3 or 4 than students with high athletic performance. Before and after touching the ball in position 3, students with basic skills were significantly prone to judge wrongly as position 4 than students with high athletic performance. Before, while and after touching the ball in position 4, students with basic skills were significantly prone to judge wrongly as position 3 than students with high athletic performance. B. After touching the ball in positions 3 and 4 of setting up movement, students with high athletic performance were significantly prone to judge wrongly as position 2 than students with basic skills. Conclusions: A. In the later stage of positions 2 or 3 of setting up movement, it was harder for novices to predict setting up movement of the arm or the fingers, so they used the false body movement of position 4 as prediction precue. Thus novices were induced to judge wrongly as position 4. B. In the later stage of position 3 of setting up movement, it was easier for masters to use the arms or the fingers as prediction precue, the raising movement induced masters to significantly judge wrongly as position 2.
