Resting respiratory sinus arrhythmia (RSA) was assessed among 111 adult participants. These individuals were then asked to watch a positive or negative affective film in either a natural manner or while exaggerating their facial response. Facial reactions to the film were video-recorded and subsequently rated in terms of facial affect. Participants also self-reported the valence of their emotional experience. Results from regression analyses revealed that persons with low resting RSA behaviorally evidenced a more negative facial response to the negative film under natural-watch conditions. Low RSA individuals were also less able to modulate (i.e., amplify) their facial response to the negative film. In terms of self-report measures, persons in the exaggerate condition reported more positive affect to the positive film than did those in the natural-watch condition. Results suggest that cardiac vagal control is inversely associated with negative facial expression but positively associated with facial regulation ability to negative stimuli.
对111名成年参与者进行了静息呼吸性窦性心律不齐（RSA）评估。然后要求这些个体以自然方式或在夸大面部反应的同时观看一部积极或消极情感的影片。对影片的面部反应进行了视频记录，随后对面部情感进行了评分。参与者还自我报告了他们情感体验的效价。回归分析结果显示，静息RSA较低的人在自然观看条件下对消极影片表现出更消极的面部反应。静息RSA较低的个体也较难调节（即放大）他们对消极影片的面部反应。在自我报告测量方面，在夸大条件下的人对积极影片报告的积极情感比在自然观看条件下的人更多。结果表明，心脏迷走神经控制与消极面部表情呈负相关，但与对消极刺激的面部调节能力呈正相关。
