本研究目的在探討黃白兩種不同顏色對訊息處理過程的影響效果。針對兩種顏色在反應時間、中樞訊息處理速度、周邊執行速度及事件關連電位 FSP、SN、N2b、P300 等指標加以分析檢測。參與者為 24 名身體健康的大學在學男生，年齡 20 至 24 歲，參與者隨機分派至黃色組與白色組各 12 名。刺激呈現是以電腦黑色螢幕為背景的圓形色圈，以具有缺口的色圈（機率為 1/5 ）為目標刺激，受試者須按壓按鍵反應。目標刺激隨機呈現。 正式測試時黃色組使用黃色色圈而白色組則使用白色色圈。經分析結果顯示黃色與白色在反應時間、中樞訊息處理速度、周邊執行速度及事件關連電位 FSP、SN、N2b 之延遲時間均無顯著差異。 然而，白色的 P300 的延遲時間（ latency ）短於黃色，代表中樞訊息處理過程中刺激評估階段黃色刺激的難度有高於白色刺激之傾向。

　　　　　The purpose of this study was to examine effects of yellow and whitecolors on information processing. Specially, the parameters employed to measureinformation processing included reaction time (RT), the central informationprocessing speed and the peripheral executing speed and FSP、 SN、 N2b、 P300 ofthe event related potentials (ERP). Twenty-four male college students, from 20to 24 years old participated in this study. That participants were randomlyassigned to yellow and white color group every. Visual odd ball paradigm wasused to challenge participants' information processing capacity. EEG, EMG, andbutton press were employed to collect dependent measures. Independent t test oneach dependent measures showed that the reaction time (RT), the centralinformation processing speed, the peripheral executing speed, the latencies ofFSP, SN and N2b were not different between yellow and white colors. However, theP300 latency for white color is shorter than that of yellow, indicate a morecomplicate stimulus evaluation processing for yellow color.
