以問卷調查和HRV評估方法探討禪定組及控制組的自閉症潛在性

Abstract

本研究主要在探討自閉症商數(Autism Spectrum Quotient, ASQ)和心率變異(Heart Rate Variability, HRV)之間的關聯性。過去自閉症研究多在探討高頻率範圍(High Frequency, HF)和低頻率範圍(Low Frequency, LF)，鮮少討論自閉症與極低頻範圍(Very Low Frequency, VLF)的關係。本研究分別以時域分析和頻域分析兩種不同方式作為評估標準，分析方法為1) 潘凱圖分析(Poincaré Plot Analysis, PPA)和2)連續小波轉換(Continuous Wavelet Transformation, CWT)。實驗設計分兩個部分，1)從2683位受測者中挑選出18 – 30歲的受測者共1264位，以單尾T檢定(one-tailed Student's t-test analysis)探討禪定經驗的有無與ASQ平均分數的關係，2)控制組26位、禪定組8位，共34位學生，於持續專注力實驗(Continuous Attention Test, CAT)中，探討兩組的平均錯誤率以及HRV。 實驗一結果顯示有禪定經驗並能雙盤者的ASQ平均分數比無禪定經驗者低10%，且單尾T檢定分析結果呈現顯著差異(p**<0.01)；實驗二結果顯示禪定組於CAT中平均錯誤率較控制組低，且於控制組中VLF功率較低者的ASQ平均分數較其餘控制組高12%。

In this research, the correlation between Autism Spectrum Quotient (ASQ) and Heart Rate Variability (HRV) is discussed. In the past decade, the relationship between Autism and power of HRV in High Frequency (HF, 0.15 – 0.4 Hz) and Low Frequency (LF, 0.04 – 0.15 Hz) was emphasized, however, Very Low Frequency (VLF, 0.0033 – 0.04 Hz) power of Autism was seldom explored. We used two different methods, Poincaré Plot Analysis (PPA) and Continuous Wavelet Transformation (CWT) to do time domain analysis and frequency domain analysis, respectively. There are two steps of the experiment: 1) Choose 1264 participants aged 18 – 30 out of 2683 participants to discuss the relationship between Chan Ding experience and the average value of ASQ scores with one-tailed Student's t-test analysis. 2) In Continuous Attention Task (CAT) test, the average of error rate and HRV are measured in the control group of 26 participants and Chan Ding group of 8 participants. The result of experiment I reveals that the average ASQ scores of Chan-Ding group with full-lotus posture was 10% lower than that of the control group. The one-tailed Student's t-test analysis result of two group is significant (p**<0.01). In the experiment II, the error rate of Chan Ding group is lower than that of the control group in CAT test. In the control group, the average value of ASQ scores of members without VLF-dominances is 12% higher than that of the other members.
