与不同情绪相关的特定躯体状态的存在仍然存在争议。在这项研究中，我们调查了在恐惧，愤怒，悲伤和快乐的经验，心肺活动的配置文件。记录了43名健康志愿者在回忆和体验一个或两个强有力的情感自传体事件和中性事件的过程中的心电图和呼吸活动。单变量统计表明，四种情绪彼此不同，从中性控制条件下的几个线性和光谱指数的心肺活动。使用探索性主成分分析（PCA）将因变量进一步减少到五个生理上有意义的因素。对这些因素进行的方差和效应量估计的多变量分析证实了四种情绪条件之间的差异。使用PCA因子预测情绪的逐步判别分析导致四种情绪的分类率为65.3%（机会=25%; p=0.001），成对判别的分类率为72.0-83.3%（机会=50%; p < 0.05）。这些调查结果可以被认为是初步的，鉴于小样本的多变量方法已被应用。然而，这项研究强调，需要更好地表征多维因素参与心肺调节情绪。这些结果与外周生理活动的不同模式与不同情绪相关联的观点一致。(c)2005 Elsevier B.

The existence of specific somatic states associated with different emotions remains controversial. In this study, we investigated the profile of cardiorespiratory activity during the experience of fear, anger, sadness and happiness. ECG and respiratory activity was recorded in 43 healthy volunteers during the recall and experiential reliving of one or two potent emotional autobiographical episodes and a neutral episode. Univariate statistics indicated that the four emotions differed from each other and from the neutral control condition on several linear and spectral indices of cardiorespiratory activity. Dependent variables were further reduced to five physiologically meaningful factors using an exploratory principal component analysis (PCA). Multivariate analyses of variance and effect size estimates calculated on those factors confirmed the differences between the four emotion conditions. A stepwise discriminant analyses predicting emotions using the PCA factors led to a classification rate of 65.3% for the four emotions (chance=25%; p=0.001) and of 72.0-83.3% for pair-wise discrimination (chance=50%; p's < 0.05). These findings may be considered preliminary in view of the small sample on which the multivariate approach has been applied. However, this study emphasizes the need to better characterize the multidimensional factors involved in cardio-respiratory regulation during emotion. These results are consistent with the notion that distinct patterns of peripheral physiological activity are associated with different emotions. (c) 2005 Elsevier B.V. All rights reserved.
