目的：探討軟式網球不同技能水準選手與不同位置選手深度知覺之比較。方法：以電動式深度知覺檢測儀，測驗國內軟式網球選手及非運動員共計110位（優秀組22位、一般組43位與非運動員組45位）之深度知覺能力。統計以獨立樣本One-way ANOVA單因子變異數與t檢定進行考驗，顯著水準定為α = .05。結果：不同技能水準選手之深度知覺在慢速（近至遠）為優秀組與一般組顯著優於非運動員組；慢速（遠至近）為優秀組與一般組顯著優於非運動員組；快速（遠至近）為一般組顯著優於非運動員組。不同位置選手於慢速（近至遠）、慢速（遠至近）、快速（近至遠）、快速（遠至近）之深度知覺均無顯著差異。結論：軟式網球不同運動水準選手在不同方向與速度之深度知覺能力有顯著差異，擔任不同位置軟式網球選手之深度知覺能力則無顯著差異。

Purpose: This study mainly focuses on the comparison of depth perception among soft tennis athletes with different skill levels and in different positions. Method: There are 112 participants, including domestic soft tennis athletes and non-athletes (22 elite athletes, 45 general athletes, and 45 non-athletes) who receive the depth perception test by electric depth perception tester. Independent One-way ANOVA and t test was used to analyze these data and the significant level was set at α = .05. Results: Among all players with different levels of skills, depth perception of elite and general athletes is significantly better than non-athletes in the low-speed part (from near to far). Elite and general athletes also overpass non-athletes in the low-speed part (from far to near) and in the high-speed part (from far to near). In the low-speed parts (from near to far and from far to near) and the high-speed parts (from near to far and from far to near), depth perception of players in different positions has no particular difference. Conclusion: Depth perception ability of soft tennis players with different levels of skills is significantly different at various direction and speed. In the other hand, depth perception ability of soft tennis players in different positions has no significant difference.
