父母和婴儿之间的生理过程的协调被认为是支持婴儿适应的关键行为，但我们对学龄前时期的亲子生理协同调节知之甚少。本研究探讨是否随时间变化的变化，父母和儿童呼吸性窦性心律失常（RSA）表现出协同调节（跨人动态）占父母和儿童RSA的个体差异，以及是否有差异，这些副交感神经过程中的儿童的外化问题。母子二人组（N = 47;儿童年龄M = 3 1/2岁）从事三个实验室任务（自由游戏，清理，拼图任务）18分钟，在此期间收集RSA数据。多水平耦合自回归模型显示，母亲和学龄前儿童表现出积极的RSA的共同调节，母亲RSA的变化预测在同一方向的变化，在儿童RSA，反之亦然，控制的稳定性内的人RSA随着时间的推移和个体差异的总体平均RSA。然而，当儿童的外化行为较高，共调节是负的，这样的变化，在实时母亲和儿童RSA表现出分歧，而不是积极的一致性。研究结果表明，母亲和学龄前儿童在实时互动过程中共同调节RSA，但儿童较高的外化行为问题与这些过程中的中断有关。(c)2015 Wiley Periodicals，Inc.
The coordination of physiological processes between parents and infants is thought to support behaviors critical for infant adaptation, but we know little about parent-child physiological coregulation during the preschool years. The present study examined whether time-varying changes in parent and child respiratory sinus arrhythmia (RSA) exhibited coregulation (across-person dynamics) accounting for individual differences in parent and child RSA, and whether there were differences in these parasympathetic processes by children's externalizing problems. Mother-child dyads (N = 47; Child age M = 3 1/2 years) engaged in three laboratory tasks (free play, clean up, puzzle task) for 18 min, during which RSA data were collected. Multilevel coupled autoregressive models revealed that mothers and preschoolers showed positive coregulation of RSA such that changes in mother RSA predicted changes in the same direction in child RSA and vice versa, controlling for the stability of within-person RSA over time and individual differences in overall mean RSA. However, when children's externalizing behaviors were higher, coregulation was negative such that changes in real-time mother and child RSA showed divergence rather than positive concordance. Results suggest that mothers and preschoolers do coregulate RSA during real-time interactions, but that children's higher externalizing behavior problems are related to disruptions in these processes.
