呼吸性窦性心律失常（RSA）与价和觉醒之间的关系尚不清楚。在本研究中，我们评估了情绪反应与RSA的张力或任务相关变化之间的联系。明确;研究了心跳间隔、RSA和皮肤电导变化对情绪刺激的效价和唤醒值的敏感性。本研究还探讨了主观性、表现性和生理性情绪反应与主观性、表现性和生理性情绪反应的关系。在基线和观影期间收集了56名成年人的反应测量。补品RSA与任何反应措施均无显著相关。增加的皮肤电导和降低的RSA与独立于价的觉醒有关。心跳间隔与情感效价有关，而与觉醒无关。这些发现表明，在评估情绪唤醒时，RSA可能是皮肤电导测量的有用辅助。
The relationship between respiratory sinus arrhythmia (RSA) and valence and arousal remains unclear. In the present study, the associations between emotion responses and tonic or task-related changes in RSA were assessed. Specifically; the sensitivities of changes in interbeat interval, RSA, and skin conductance to the valence and arousal values of emotional stimuli were examined. This study also explored the association between tonic RSA and subjective, expressive, and physiological emotional responses. Response measures were collected from 56 adults during baseline and film-viewing periods. Tonic RSA was not significantly related to any of the response measures. Increased skin conductance and decreased RSA were associated with arousal independent of valence. Interbeat interval was related to affective valence and not arousal. These findings suggest that RSA may be a useful adjunct to skin conductance measures in assessing emotional arousal.
