There has been an increased interest in the study of underlying autonomic correlates of emotions. This study tests the hypothesis that high levels of high-frequency heart rate variability (HF HRV) are associated with positive emotions. In addition, we hypothesize that this association will differ according to the type of positive emotion. Also, based on recent findings, we tested the hypothesis that this relationship would be nonlinear. Resting-state HRV was collected and self-report measures of different positive emotions were administered to a sample of 124 volunteers.
Results suggested that there was a quadratic relationship between high-frequency heart rate variability and positive emotions associated with safeness and contentment, but not with positive emotions associated with excitement or lack of arousal. Our data suggests that different positive emotions may be characterized by qualitatively distinct profiles of autonomic activation. Also, given the role of positive emotions in social affiliation, and particularly positive emotions associated with a quiescence motivational state, results are interpreted in light of theoretical accounts that highlight the importance of vagal regulation for social behavior.
人们对研究情绪潜在的自主相关因素越来越感兴趣。本研究检验了以下假设：高频心率变异性（HF HRV）水平高与积极情绪有关。此外，我们假设这种关联会因积极情绪的类型而不同。此外，基于最近的发现，我们检验了这种关系是非线性的假设。采集静息状态 HRV，并对 124 名志愿者进行不同积极情绪的自我报告测量。
结果表明，高频心率变异性与与安全和满足感相关的积极情绪之间存在二次关系，但与与兴奋或缺乏唤醒相关的积极情绪之间没有关系。我们的数据表明，不同的积极情绪可能具有不同的自主激活特征。此外，鉴于积极情绪在社会联系中的作用，特别是与平静的动机状态相关的积极情绪，结果是根据强调迷走神经调节对社会行为重要性的理论观点来解释的。
