Maternal psychophysiological responses to toddlers' distress to novelty may have important implications for parenting during early childhood that are relevant to children's eventual development of social withdrawal and anxiety. Likely, these responses depend on intrapersonal, interpersonal, and contextual factors. The current study investigated the time course of respiratory sinus arrhythmia (RSA) across two laboratory novelty episodes, one low threat and one moderate threat, in 120 mothers of 2-year-old toddlers. Growth models tested context differences in and correlates of dynamic patterns of RSA. Dynamic patterns differed between tasks and according to mothers' perceptions of and distress about toddler shyness. Thus, changes in mothers' RSA across toddlers' interactions with novelty seem to depend on the context as well as how mothers perceive and respond to their toddlers' shyness.
母亲对幼儿对新奇事物的痛苦的心理生理反应可能对幼儿期的育儿有重要影响，这与儿童最终发展出社交退缩和焦虑有关。这些反应可能取决于个人内在、人际和环境因素。本研究在两个实验室新奇事件中，对 120 名 2 岁幼儿的母亲的呼吸窦性心律失常（RSA）的时间过程进行了研究，一个是低威胁，一个是中等威胁。增长模型测试了 RSA 动态模式的任务差异和相关因素。任务之间的动态模式不同，这取决于母亲对幼儿害羞的看法和困扰程度。因此，母亲的 RSA 在幼儿与新奇事物的互动过程中的变化似乎取决于环境以及母亲如何看待和应对幼儿的害羞。
