Eighteen children (age: 9.38 ± 0.27 years old) were recruited as the participants for this study, and asked to assess RT and balance performance separately and simultaneously as following five conditions: simple RT (0-bit decision), choice RT (1-bit decision), single balance control, balance control with simple RT, and balance control with choice RT. Biodex 950-300 balance system and You-Shang response timer were used to record and analyze the postural stability and information processing speed (RT) respectively for the participants. Repeated measures one-way ANOVA with HSD post-hoc test and 2 (balance) × 2 (amount of information processing) repeated measures two-way ANOVA were used to test the parameters of balance performance and RT (α = .05). The results showed the overall stability index in 1-bit decision was lower than in 0-bit decision, and the mean deflection in 1-bit decision was lower than in single balance performance. Simple RTs were faster than choice RTs both in single task condition and dual task condition. It indicated that the chronometric approach of RT could use to infer the attention requirement of the secondary task. However, this study did not find that the balance performance be interfered for children by the increasing of the amount of information processing.目　次 第一章　緒論……………………………………………………………1 　第一節　問題背景……………………………………………………1 　第二節　研究目的……………………………………………………4 　第三節　名詞解釋與操作性定義……………………………………5 　第四節　研究範圍與限制……………………………………………7 　第五節　研究的重要性………………………………………………7 第二章　理論基礎與文獻探討…………………………………………9 　第一節　訊息處理理論………………………………………………9 　第二節　訊息處理量與反應時間……………………………………13 　第三節　注意是容量有限的資源……………………………………17 　第四節　雙重任務設計的研究………………………………………21 　第五節　兒童的平衡發展……………………………………………24 　第六節　結語…………………………………………………………26 第三章　研究方法………………………………………………………27 　第一節　實驗參與者…………………………………………………27 　第二節　實驗儀器與設備……………………………………………28 　第三節　實驗設計……………………………………………………29 　第四節　實驗流程……………………………………………………31 　第五節　處料處理與分析……………………………………………32 第四章　結果與討論……………………………………………………33 　第一節　不同情境下平衡表現參數…………………………………33 　第二節　不同情境下反應時間與選擇反應時間……………………37 　第三節　綜合討論……………………………………………………40 第五章　結論與建議……………………………………………………43 　第一節　結論…………………………………………………………43 　第二節　建議…………………………………………………………44 引用文獻…………………………………………………………………45 　一、中文部分…………………………………………………………45 　二、英文部分…………………………………………………………45272014 bytesapplication/pdf容量理論;反應時間;Hick定律capacity theory;reaction time;Hick’s lawthesis
