One of the primary tenets of polyvagal theory dictates that parasympathetic influence on heart rate, often estimated by respiratory sinus arrhythmia (RSA), shifts rapidly in response to changing environmental demands. The current standard analytic approach of aggregating RSA estimates across time to arrive at one value fails to capture this dynamic property within individuals. By utilizing recent methodological developments that enable precise RSA estimates at smaller time intervals, we demonstrate the utility of computing time-varying RSA for assessing psychophysiological linkage (or synchrony) in husband-wife dyads using time-locked data collected in a naturalistic setting.
多元迷走神经理论的一个主要原则表明，副交感神经对心率的影响（通常通过呼吸性窦性心律不齐（RSA）来估计）会随着环境需求的变化而迅速改变。目前将RSA估计值随时间汇总以得出一个值的标准分析方法，无法捕捉个体内部的这种动态特性。通过利用最近的方法学进展，这些进展能够在更小的时间间隔内进行精确的RSA估计，我们证明了计算随时间变化的RSA在使用自然环境中收集的时间锁定数据评估夫妻二元组的心理生理联系（或同步性）方面的效用。
