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.
呼吸性窦性心律不齐（RSA）与情绪效价及唤醒之间的关系尚不清楚。在本研究中，评估了情绪反应与RSA的静息或任务相关变化之间的关联。具体而言，研究了心跳间期、RSA和皮肤电传导变化对情绪刺激的效价和唤醒值的敏感性。本研究还探讨了静息RSA与主观、表达性和生理性情绪反应之间的关联。在基线期和观影期收集了56名成年人的反应指标。静息RSA与任何反应指标均无显著相关性。皮肤电传导增加和RSA降低与唤醒相关，与效价无关。心跳间期与情感效价相关，与唤醒无关。这些发现表明，在评估情绪唤醒方面，RSA可能是皮肤电传导测量的有用辅助手段。
