本研究探讨了自主神经系统（ANS）模式在实验操纵的情绪。除了一部中性的对照电影外，还向34名大学年龄的受试者展示了先前显示的引起娱乐，愤怒，满足，厌恶，恐惧和悲伤的电影剪辑，同时记录了皮肤电导，血压和心电图（ECG），以及自我报告的影响。心动周期的平均值和平均逐次差均由心电图导出。模式分类分析显示，情绪特异性自主模式的所有情绪条件下，除了厌恶，所有的情绪条件下表现出显着的模式，使用自我报告。判别函数分析被用来描述离散的情绪在维度情感空间的位置，使用自我报告和ANS变量。研究结果表明，效价和激活的尺寸描绘的结构自我报告的情绪，但效价更准确地描述为接近撤回时，适用于自主反应在离散的情绪。研究结果提供了进一步的支持情绪特定的ANS活动的存在，并与情感空间的混合离散维模型是一致的。(C)2003 Elsevier B.V.保留所有权利。
The present study addressed autonomic nervous system (ANS) patterning during experimentally manipulated emotion. Film clips previously shown to induce amusement, anger, contentment, disgust, fear and sadness, in addition to a neutral control film, were presented to 34 college-aged subjects while skin conductance, blood pressure and the electrocardiogram (ECG) were recorded, as was self-reported affect. Both mean of and mean successive difference of heart period were derived from the ECG. Pattern classification analyses revealed emotion-specific autonomic patterning for all emotion conditions except disgust; all emotion conditions exhibited significant patterning using self-report. Discriminant function analysis was used to describe the location of discrete emotions within dimensional affective space using both self-report and ANS variables. Findings suggest that the dimensions of valence and activation portray the structure of self-reported emotion, but that valence is more accurately described as approach-withdrawal when applied to autonomic responses during discrete emotions. The findings provide further support for the existence of emotion-specific ANS activity, and are consistent with a hybrid discrete-dimensional model of affective space. (C) 2003 Elsevier B.V.
