本研究的主要目的在探討不同年段與運動訓練之有無之國小男童在單純反應時間 、選擇反應時間及反應選擇中樞處理時間的差異情形 (N=64)， 藉以說明「年齡」與「運動 訓練之有無」對個體反應能力發展的影響。 以 TAKEI 「多元表現型態區辨反應測驗裝置」 為研究工具，採用受試者間的設計。 自變項分別為年段 (低、中、高 ) 及運動訓練之有無 (一般學童、羽球選手 )，藉由操弄不同作業難度所獲得之單純、選擇反應時間， 並透過時 間分解法計算出個體在反應選擇中樞處理時間，作為量化指標。所得資料，採事前比較變異 數分析進行統計考驗 (ぽ =.05) 。 結果發現， 不論在單純反應時間 (即反應的基準線 )(SRT)、 選擇反應時間 (CRT) 及反應選擇中樞處理時間 (CRT-SRT) 的比較上皆呈現出:( 一 ) 中年級與低年級學童間的差異達顯著水準； (二 ) 高年級與低年級學童間的差異達顯 著水準；(三 ) 中年級與高年級學童間的差異未達顯著水準；(四 ) 高年級學童與高年級羽 球選手間的比較達顯著差異。在本研究範圍內所獲得的結論為: 國小男童單純反應時間、選 擇反應時間及反應選擇中樞處理時間會隨著年齡的增長而獲得改善，此外，從事積極、規律 且持續二年以上的羽球訓練對於個體反應能力的發展也有相當大的助益。

　　　　　The purpose of this study was to investigate the effects of grades and athletic training on elementary schoolboys, simple reaction time, choice reaction time and the central processing time of reaction choice. Sixty-four elementary schoolboys, including 16 badminton players, were sampled from two schools, and tested with the "Discrimination Reaction Test of Multiple Performance Type" to analyze their simple reaction time, choice reaction time, and central processing time of reaction choice. With one-way ANOVA and prior comparisons, it was found taht:(1)The difference between the fourth graders and the second graders came to the significant level. (2) The difference between the sixth graders and the second graders also came to the significant level. (3) The difference between the fourth graders and the sixth graders did not come to the significant level. (4)The difference between the sixth graders and the sixth-grade badminton players came to significant level. The conclusion of this study is that elementary schoolboys' simple reaction time, choice reaction time and central processing time of reaction choice become better with growing. In addition, the active, regular badminton training for two more consecutive years is of great benefit to the development of individual's reaction ability.
