浪漫伴侣的自主神经反应协调的程度，由他们生理同步的模式所代表，似乎捕捉到了配偶之间相互影响和共同调节的重要方面。在这项研究中，我们通过心率(HR)和心率变异性(HRV)来分析夫妇的心脏同步性。27对夫妇(N=54)在实验室中完成了一项结构化的互动任务，他们讨论了这段关系的积极和消极方面。在互动过程中，使用Biopac系统记录他们的心脏测量(HR和HRV)。在实验室互动任务之前，额外的评估包括同理心的自我报告测量(夫妻的人际反应指数和人际反应指数)和关系满意度(修订的二元适应量表)。同步性计算基于伴侣的HR和HRV时间序列的加窗互相关。为了控制随机同步，使用分段洗牌创建了代理控件。我们的结果证实，与代孕测试相比，这对夫妇的互动过程中存在心脏同步。具体地说，我们发现了夫妻心率变异负(反相)同步和心率正(同相)同步的证据。此外，心率变异性和心率同步性都与自我报告数据的几个维度相关。这项研究表明，在婚姻互动的背景下，心脏同步性，特别是伴侣生理时间序列中的协变方向，可能具有重要的关系意义。
The degree to which romantic partners' autonomic responses are coordinated, represented by their pattern of physiological synchrony, seems to capture important aspects of the reciprocal influence and co-regulation between spouses. In this study, we analyzed couple's cardiac synchrony as measured by heart rate (HR) and heart rate variability (HRV). A sample of 27 couples (N = 54) performed a structured interaction task in the lab where they discussed positive and negative aspects of the relationship. During the interaction, their cardiac measures (HR and HRV) were recorded using the BIOPAC System. Additional assessment, prior to the lab interaction task, included self-report measures of empathy (Interpersonal Reactivity Index and Interpersonal Reactivity Index for Couples) and relationship satisfaction (Revised Dyadic Adjustment Scale). Synchrony computation was based on the windowed cross-correlation of both partner's HR and HRV time series. In order to control for random synchrony, surrogate controls were created using segment-wise shuffling. Our results confirmed the presence of cardiac synchrony during the couple's interaction when compared to surrogate testing. Specifically, we found evidence for negative (antiphase) synchrony of couple's HRV and positive (in-phase) synchrony of HR. Further, both HRV and HR synchronies were associated with several dimensions of self-report data. This study suggests that cardiac synchrony, particularly, the direction of the covariation in the partners' physiological time series, may have an important relational meaning in the context of marital interactions.
