本研究主要探討背景音樂及視覺干擾對認知任務表現、情緒以及專注度的影響。本研究招募114名受試者進行實驗，受試者將會在無背景音樂、高喚醒程度音樂、低喚醒程度音樂3種音樂條件，以及無視覺干擾、有視覺干擾2種條件，進行記憶任務、閱讀任務以及圖像推理任務。實驗數據以SPSS 21統計軟體進行ANOVA分析，以了解各組在不同背景音樂、視覺干擾條件下的任務表現是否有差異。實驗分析結果如下：
一、不同背景音樂條件、視覺干擾條件，對記憶任務和閱讀速度2有顯著影響。
二、相較於無背景音樂與高喚醒程度音樂，低喚醒程度音樂條件下的記憶任務表現最好；相較於高、低喚醒程度音樂，無背景音樂條件下的閱讀速度2表現最好。
三、高喚醒程度音樂會增加受試者的正向情緒分數，低喚醒程度音樂會增加受試者的負向情緒分數。
四、視覺干擾對任務專注度的影響比背景音樂的影響還大。
根據研究結果提出相關建議，作為未來背景音樂、認知任務表現、情緒、專注度等領域研究之參考。

This study focused on the effects of background music and visual distractions on cognitive task performance, emotions, and concentration. The experiment recruited 114 as participants. The subjects will perform memory tasks, reading tasks, and image reasoning tasks in three music conditions: without background music, high arousal emotional music, and low arousal emotional music, as well as no visual interference, and two conditions with visual interference. The experimental data were analyzed by ANOVA with SPSS 21 statistical software to understand whether the task performance of each group was different under different background music and visual interference conditions. The experimental analysis results are as follows:
1.Different background music conditions and visual interference conditions have significant effects on memory tasks and reading speed 2.
2.Compared with no background music and high arousal emotional music, the memory task performance under the condition of low arousal emotional music is the best; compared with high and low arousal emotional music, the reading speed 2 without background music has the best performance.
3.High arousal emotional music increases the subjects' positive emotional scores, while low arousal emotional music increases the subjects' negative emotional scores.
4.Visual distractions affect task focus more than background music.
According to the research results, relevant suggestions are put forward, which can be used as a reference for future research in the fields of background music, cognitive task performance, emotion, and concentration.
