中文摘要 | 視覺訊息在踢毽過程中扮演很重要的角色,本文旨在探討受試者內、受試者間、失敗與成功的踢毽正踢τ(Tau)值是否有差異性。本研究利用JVC GR-DVL 9800一台(120Hz)以及Kwon 3D軟體(濾波為6Hz)擷取並計算出30名學童踢毽正踢動作的τ值,採用的統計方法有相依樣本t考驗(α=.05)、獨立樣本單因子變異數分析,若達顯著水準以杜凱氏(Tukey)法進行事後比較,統計水準定為α=.05。本研究之結果:一、受試者內τ值的差異情形,除了3位受試者(編號12、24、30)外,大部分均未達到顯著差異(p<.05);二、受試者間τ值達顯著差異(p<.05);三、失敗與成功的踢毽正踢τ值未達顯著差異(p<.05)。本研究之結論證明踢毽正踢的τ值存在且各受試者有不同的τ值,符合生態心理學的訊息恆定性的觀念。並由結果可知,在踢毽正踢動作中,τ是判斷踢毽時機的訊息依據,但不是唯一的關鍵。 |
英文摘要 | Visual information played an important role during the process of the shuttle-cock kicking. The purpose of this study was to compare the differences of τ (Tau) value within subjects, between subjects, and the differences between the failure and success for shuttle-cock kicking. In this study, we used a camera (JVC GR-DVL9800, 120 Hz) and Kwon 3D software with 6 Hz cutoff frequency to figure-out the τ of shuttle-cock front kicking from 30 students. This research was based on the statistical methods of repeated measures t-test (α=.05) and one-way ANONA. The result of this study was as follows: 1. Except for three subjects (number 12, 24, 30), almost all subjects' τ didn't achieved significantly (p<.05) differences within subjects. 2. All subjects' τ achieved significantly differences between subjects (p<.05). 3. No differences of τ between failure and success (p<.05) was observed. The study proved that τ existed within subjects and every subject had different τ for shuttle-cock front kicking. The results demonstrated the concept of ecological psychology that the information was consistent. Therefore, τ also one of the main information source for shuttle-cock front kicking. |
