探討空手道不同技能水準選手與大專生深度知覺之差異。方法：以電動式深度知覺檢測儀，測驗國內空手道選手及大專生共計67 位（優秀組22 位、一般組23 位與大專組22 位）之深度知覺能力。以獨立樣本One-way ANOVA 單因子變異數分析，比較三組深度知覺：25 mm/sec 與50 mm/sec（近至遠、遠至近）差異。顯著水準定為α =.05。結果：三組在25 mm/sec 近至遠、25 mm/sec 遠至近與50 mm/sec 近至遠、50mm/sec 遠至近之深度知覺，優秀組顯著優於大專組（p ＜ .05）；而優秀組與一般組，以及一般組與大專組在25 mm/sec 近至遠、25 mm/sec 遠至近與50 mm/sec 近至遠、50 mm/sec遠至近則無顯著差異（p ＞ .05）。結論：空手道優秀組深度知覺優於大專組，但優秀組與一般組，以及一般組與大專組之深度知覺相較下則無顯著差異。

The aim of this study was to explore the difference in depth perception between karate athletes of differing skill levels and normal college students. Methods: The subjects of this study were 67 college students who were divided into three groups according to the level of their karate ability: 22 in the ＂outstanding＂ group, 23 in the ＂average＂ group, and 22 were normal students. Their depth perception ability was tested using an electric depth perception tester and analyzed by One-way ANOVA with single sample. Differences in depth perception-25 mm/sec and 50 mm/sec (near-to-far and far-to- near) of the three groups were compared. The level of significance was set at α = .05. Results: Among these three groups, the depth perception at 25 mm/sec (near-to-far and far-to-near) and at 50 mm/sec (near-to-far and far-to-near) of the outstanding group was significantly better than the normal group (p ＜ .05). However, at 25 mm/sec (near-to-far and far-to-near) and at 50 mm/sec (near-to-far and far-to-near), there was no difference between the outstanding and average groups, or between the average and normal groups (p ＞ .05). Conclusions: The outstanding group had superior depth perception when compared to the college group, but differences between the outstanding and the average group, and between the average and college group, were not obvious.
