An exploration of the physiological correlates of subjective emotional states has theoretical and practical significance. Previous studies have reported that subjective valence and arousal correspond to facial electromyography (EMG) and electrodermal activity (EDA), respectively, across stimuli. However, the reported results were inconsistent, no study investigated subjective-physiological concordance across time, and measures of arousal remain controversial. To investigate these issues, while healthy adults (n = 20) viewed emotional films, we assessed overall and continuous ratings of valence and arousal and recorded EMG from the corrugator supercilii and zygomatic major, EDA from the palms and forehead, and nose-tip temperature. The corrugator and zygomatic EMG were negatively and positively associated with valence ratings, respectively, across stimuli and time. EDA (both sites) and nose-tip temperature were positively and negatively associated with arousal ratings, respectively, across stimuli and time. It is concluded that subjective emotional valence and arousal dynamics have specific physiological correlates.
探索主观情绪状态的生理相关性具有理论和实际意义。先前的研究报告称，主观效价和唤醒分别对应于跨刺激的面部肌电图（EMG）和皮肤电活动（EDA）。然而，报告的结果不一致，没有研究调查主观生理一致性随时间的变化，而且唤醒的测量仍然存在争议。为了研究这些问题，当健康成年人（n=20）观看情绪电影时，我们评估了效价和唤醒的整体和连续评分，并记录了皱眉肌和颧大肌的 EMG、手掌和前额的 EDA 以及鼻尖温度。皱眉肌和颧大肌 EMG 分别与跨刺激和时间的效价评分呈负相关和正相关。EDA（两个部位）和鼻尖温度分别与跨刺激和时间的唤醒评分呈正相关和负相关。结论是，主观情绪效价和唤醒动态具有特定的生理相关性。
