摘要

本研究目的在以腦波α1、α2與β1連貫性來探討簡單、選擇反應時間快慢之差異。本研究以28名大專、高中甲組優秀桌球選手為實驗參與者，分別進行簡單與選擇反應時間兩種作業，擷取個人反應時間較快與較慢之腦波資料，經過腦波訊號處理以重複量數t檢定比較α1、α2與β1腦波連貫性。本研究結論如下：一、個體進行簡單反應時間作業時，反應時間快慢與T3-Fz、T4-FZ的腦波連貫性（顳葉區、運動計畫區之間的溝通程度）有關。反應時間較快時，T3-Fz、T4-FZ之腦波連貫性較低。二、個體進行選擇反應時間作業時，腦波連貫性亦與反應時間快慢有關。反應時間較快時，除了有較低的左顳葉與運動計畫區之腦波連貫性外，左頂葉區與運動計畫區之腦波連貫性則增加。

The main purpose of this study was to examine the relationship between reaction time and EEG α1, α2 and β1 coherence. The participants were 28 skilled, male table tennis players. All participants completed both simple and choice reaction time tasks. The pre-imperative stimulus EEG was segmented into two epochs and EEG from each trial was further categorized into fast and slow reaction time groups. Paired t tests were employed to compare EEG α1, α2 and β1 coherence between fast and slow RT. The results of this study follows:
1.EEG coherence were related to simple reaction time performance. Specifically, lower coherences between T3-Fz and T4-Fz were associated with faster RT.
2.EEG coherence also was capable of differentiating performance in choice RT task. Specifically, faster RT was associated with lower T3-Fz and higher.P3-Fz coherence.
