摘要

本研究在不同前線索情境下，比較不同技能水準的桌球運動員，預期桌球方向準確率，驗證預期能力為高水準運動員重要特質，並進一步找出主要預期時間線索。本研究的受試者（N=20），分成專家組與初學組。專家組平均球齡11.2年、初學組平均球齡0.7年，利用影像剪輯系統，將擊球影片剪輯成，觸球前66毫秒，觸球前33毫秒，觸球瞬間，並將影片剪輯成測驗帶，採平衡設計，以比較初學、專家桌球不同方向預期準確率，測驗後以SPSS 12.0，收集統計，採混合設計二因子變異數分析考驗，當交互作用達顯著時，進行單純主要效果考驗，並進行事後比較。顯著水準（α）皆訂為.05。本研究獲得結論為：在三種不同線索情境下，預期準確率有顯著的不同，顯示出隨著前線索的累加，運動員預期準確性有逐漸增加，直到觸球前一格到觸球瞬間，在關鍵時刻運動員可有效利用情境中的線索做出正確的預期。

This research before difference under clue situation. Compared with different skill level pool athlete. Anticipated pool direction rate of accuracy. Confirms the anticipated ability for the high standard athlete important special characteristic. And further discovers the main anticipated time clue. This research trying (N=20). Divides into the expert group and the poor hand group. Expert group average number of years engaging in a ballgame sport in 11.2, poor hand group average number of years engaging in a ball-game sport 0.7 year. Using phantom editing system. Will hit a ball the film cutting to become. Touches the ball first 66 milliseconds. Touches the ball first 33 milliseconds. Touches the ball instantaneous. And becomes the film cutting examines the belt. Picks the balanced design. Compares the poor hand, the expert pool different direction anticipated rate of accuracy. After the examination, by SPSS12.0, the collection statistics, picks the mix design two factor variance analysis test, when the correlation reaches is remarkable, carries on the pure main effect test, after advancing together the conduct, comparison. The remarkable standard (Alpha) all subscribes is .05 This research obtains the conclusion is: Under three kind of different clue situations, the anticipated rate of accuracy has the remarkable difference, demonstrated before clue's accumulation, the athlete anticipated accuracy has increases gradually, until touches the ball preceding standard to touch the ball instantaneous, in the critical moment athlete may use in the situation the clue to make correct anticipation effectively.
