中文摘要 本論文找了43位受測者分為有靜坐經驗與無靜坐經驗兩組,進行專注式靜坐練習和使用IAPS作情緒刺激實驗,實驗中量測心電圖(ECG)與腦波圖(EEG),以頻域方式分析腦波和心率變異度,觀察在靜坐練習時自律神經系統和腦部活動的變化。本論文提出一個以Alpha波變化搭配模糊理論來評估靜坐表現的方式,讓靜坐練習者了解自己靜坐的程度並當作客觀的分組方式探討靜坐對於圖片情緒刺激的影響。
實驗結果顯示靜坐時Alpha波能量上升、低高頻比下降、高頻功率下降、低頻功率上升,且有靜坐經驗組變化比無靜坐經驗組明顯,表示靜坐可能對於放鬆程度、自律神經平衡和腦部穩定有功效且持續的靜坐練習能有更明顯的效果。以Alpha波能量評估靜坐表現發現靜坐表現與靜坐經驗有一定程度相關,無靜坐經驗受測者只有少數人能達到一定的靜坐表現。圖片情緒刺激時,靜坐表現差和無靜坐經驗組的低高頻比和高頻功率變化明顯且代表感官刺激的Beta波能量平均較高,對於情緒刺激影響較大。靜坐表現好和有靜坐經驗組的低高頻比和高頻功率無明顯變化且代表感官刺激的Beta波能量平均較低,對於情緒刺激影響較小。推論靜坐練習對於降低情緒刺激帶來的影響有一定功效。
英文摘要 This work groups subjects by their duration of experience with meditation, then measures their ECG and EEG during meditation and emotion-stimulating experiments by using IAPS. By analyzing EEG and HRV in the frequency domain we can observe how ANS and brain actions change. This research proposes a method to objectively estimate the meditation performance. In this way, subjects may self-assess their meditation performance. Subjects are sorted by objective meditation performance as well as by subjective meditation experience so as to analyze the effect of meditation in emotion-stimulating experiments.
The results show that during meditation, the power of the EEG Alpha wave and the low-frequency component of HRV increases, but the LF/HF ration and high-frequency component of HRV decreases. Compared with the group of people who have no experience with meditation, people who meditate regularly show more improvement in the power of EEG and HRV after meditation. This work demonstrates that meditation will improve the performance of balancing ANS and relaxation as well as steadying brain action. Those who have practiced meditation for a longer period of time will have better performance. During emotional stimulus, people who have inferior performance and less experience with meditation have significant changes in LF/HF ration and the high-frequency component of HRV. Furthermore, the average power of EEG Beta waves (on behalf of the sensory stimulation) is also larger. Thus, the conclusion has been reached that meditation is helpful to reduce the effects of emotional stimulus.
