情绪意识体验的双极价-唤醒模型在情绪研究中占有重要地位。在这项工作中，我们在视觉刺激引发的感觉的背景下检验了该模型的有效性。特别是，我们考察了唤醒在解释生理唤醒(皮肤电活动，EDA)和自我报告的感觉(在个体之间和个体内部的特定项目反应水平上)时，是否对双变量效价(快乐和不快乐的单独测量)具有独特的贡献。我们的结果表明，唤醒的自我报告在预测EDA方面既没有优势，也没有在模型中存在效价时的独特贡献。使用贝叶斯信息标准确认了对零假设的接受。在预测整体感觉方面，唤醒也没有表现出比效价更好的优势，但表现出了一个很小的独特成分(解释了1.5%到4%的方差)。这些结果对情绪研究中的实验设计和有意识体验的基础都有实际意义。
The bipolar valence-arousal model of conscious experience of emotions is prominent in emotion research. In this work, we examine the validity of this model in the context of feelings elicited by visual stimuli. In particular, we examine whether arousal has a unique contribution over bivariate valence (separate measures for pleasure and displeasure) in explaining physiological arousal (electrodermal activity, EDA) and self-reported feelings at the level of item-specific responses across and within individuals. Our results suggest that self-reports of arousal have neither an advantage in predicting EDA nor make a unique contribution when valence is present in the model. Acceptance of the null hypothesis was confirmed with the use of the Bayesian information criterion. Arousal also showed no advantage over valence in predicting global feelings, but demonstrated a small unique component (1.5% to 4% of variance explained). These results have practical implications for both experimental design in the study of emotions and the underlying bases of their conscious experience.
