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.
本研究探讨了实验诱发情绪过程中的自主神经系统（ANS）模式。除了中性对照影片外，向34名大学生受试者播放先前已证明能诱发娱乐、愤怒、满足、厌恶、恐惧和悲伤情绪的影片片段，同时记录皮肤电导、血压和心电图（ECG），以及自我报告的情感体验。从心电图中得出心动周期的均值和均值逐差。模式分类分析揭示了除厌恶外所有情绪状态下特定情绪的自主神经模式；所有情绪状态在自我报告中均呈现出显著模式。判别函数分析用于使用自我报告和自主神经变量来描述离散情绪在维度情感空间中的位置。研究结果表明，效价和激活维度描绘了自我报告情绪的结构，但当应用于离散情绪期间的自主神经反应时，效价更准确地描述为趋近-回避。这些发现为特定情绪的自主神经活动的存在提供了进一步支持，并与情感空间的混合离散-维度模型一致。
