集中注意力可以提升執行任務的效率，本研究針對咀嚼口香糖對人體警覺
性以及精神疲勞之影響進行了研究，本研究認為咀嚼口香糖作為提高警覺性與
減輕精神疲勞的方法中成本低且效益高的有效方法。且研究中透過腦電圖訊號
的分析進行輔助，比起傳統的問卷型實驗更可以得到較客觀的數據以佐證實驗
結果。
本研究藉由分析實驗數據檢測咀嚼口香糖對注意力造成正面影響的現象，
透過進行注意力網路測驗(Attention Network Test, ANT)以及腦電圖數據分析等
方式，驗證受測者是否於咀嚼口香糖後注意力方面產生了反應變快且正確等正
面影響，並對測驗進行時腦部活動變化進行觀測與數據蒐集，進一步分析受測
者之腦部活動是否有相對應的注意力集中現象產生，藉以對咀嚼口香糖所造成
的注意力影響提供客觀的驗證方式，最後則根據實驗結果對咀嚼口香糖是否對
注意力帶來正面成效，以及實驗中腦波訊號的變化提出探討與結論。
本研究透過對受測者 ANT 數據透過獨立樣本 t 檢定進行分析，研究結果指
出，咀嚼口香糖對於提高警覺性有顯著的影響。此外腦波數據上也可以觀察到
相較於咀嚼口香糖，不咀嚼口香糖時受測者在 alpha、theta、delta 的功率頻譜
密度(power spectral density, PSD)較高，表示不咀嚼口香糖的受測者相較於咀嚼
口香糖的受測者是較不專注或是處於精神較疲勞的狀態，透過腦波數據的觀察
驗證了過往關於咀嚼口香糖對警覺性提升以及緩解精神疲勞的相關研究。

It is believed that focus can improve the efficiency of task performance. Hence,
this research will study the effect of chewing gum to attention and mental fatigue.
Chewing gum is considered a low-cost and high-efficiency method on improving
alertness and reducing mental fatigue. Thus, this research will adopt the EEG data
and its analysis to strengthen the concept. When compared with experiments that
based on questionnaires, this study has provided a more objective source and thus
the results.
This study analyzed the experimental data, by Attention Network Test (ANT)
and EEG data analysis, to make the effect of chewing gum on attention become
explicit. The purpose is to verify whether the subjects present positive influences,
such as quicker and correct responses, on the attention after chewing gums. Based
on the observation, the changes in EEG data of the subjects' brain activities are
related with attention changes, which will provide an objective way of verifying the
effect of chewing gum on attention. The result from this study was discussed and
concluded.
This study also used the independent samples t-test to analyze the ANT data of
the subjects. The results showed that chewing gum have a significant effect on
improving alertness. In addition, by observing the EEG data that compared with
chewing gum, the power spectral density (PSD) of the subjects in alpha, theta, and
delta is higher when not chewing gums. It indicates that the subjects who do not
iv
chew gum are less focused or in a more mentally fatigued state than those who chew
gums. Through the observation of EEG data, the previous research on the
improvement of alertness and the relief of mental fatigue from chewing gum has
been verified.
