The aim of this study is to assess whether positive emotional exchanges (i.e., emotion coregulation) within the mother-child dyad play a protective role in children's physiological response to a distressing task. Specifically, we test whether positive emotion coregulation among mothers and their preschool-aged children is associated with children's respiratory sinus arrhythmia (RSA) at baseline, during, and following a frustration task. One hundred Singaporean mother-child dyads (M = 3.5 years) participated in a standardized "Laughing Task" in which positive emotional constructs were measured. Children also participated in a frustration task while RSA was continuously monitored. Hierarchical linear regressions revealed that greater maternal positive emotional responses to children were associated with child RSA at baseline and in recovery from frustration, but not during frustration. These findings have implications for the important role that positive emotion responsivity from mothers may play in children's developing autonomic response systems, and underscore the need for longitudinal work on this topic.
本研究旨在评估母子互动中的积极情绪交流（即情绪共同调节）是否对儿童应对痛苦任务的生理反应起到保护作用。具体而言，我们检验了母亲及其学龄前儿童之间的积极情绪共同调节是否与儿童在受挫任务期间和之后的呼吸窦性心律失常（RSA）有关。100 对新加坡母子对（平均年龄 3.5 岁）参与了一项标准化的“笑声任务”，在此任务中测量了积极的情绪构建。儿童还参与了一项挫折任务，同时连续监测 RSA。分层线性回归显示，母亲对孩子的积极情绪反应与孩子在基线时和从挫折中恢复时的 RSA 有关，但与挫折时无关。这些发现表明，母亲的积极情绪反应能力可能在儿童发展自主反应系统中起着重要作用，并强调了对此主题进行纵向研究的必要性。
