Respiratory sinus arrhythmia (RSA) figures prominently in emotional responding, but its exact role remains unclear. The present study tests two hypotheses: (1) Between-person differences in resting RSA are related to emotional reactivity, and (2) within-person changes in RSA are related to regulatory efforts. Pairs of women watched an upsetting film and discussed it. One woman in each of the experimental dyads was asked to either suppress or to reappraise during the conversation. Their partners and both members of the control dyads conversed naturally. Between-person differences in resting RSA were assessed with paced breathing, and within-person changes in RSA were calculated from baseline to the conversation accounting for respiration. Women with higher resting RSA experienced and expressed more negative emotion, and women who attempted to regulate their emotions either by suppressing or reappraising showed larger increases in RSA than controls.
呼吸性窦性心律不齐（RSA）在情绪反应中显著存在，但其确切作用仍不清楚。本研究检验了两个假设：（1）静息RSA的个体间差异与情绪反应性有关，（2）RSA的个体内变化与调节努力有关。女性成对观看一部令人心烦意乱的电影并进行讨论。在每个实验二元组中，其中一名女性被要求在对话过程中要么抑制情绪要么重新评估情绪。她们的伴侣以及控制二元组的两名成员进行自然对话。通过同步呼吸评估静息RSA的个体间差异，并计算从基线到对话过程中考虑呼吸因素的RSA个体内变化。静息RSA较高的女性体验到并表达了更多负面情绪，并且试图通过抑制或重新评估来调节情绪的女性相比对照组RSA的增加幅度更大。
