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.

幼儿与新奇互动过程中的母体动态呼吸窦性心律失常

母亲对幼儿对新奇事物的困扰的心理生理反应可能对幼儿时期的育儿有重要影响，这与儿童最终发展为社交退缩和焦虑有关。很可能，这些反应取决于个人内在、人际关系和环境因素。目前的研究调查了 120 名 2 岁幼儿的母亲在两次实验室新奇事件（一次低威胁和一次中度威胁）中发生呼吸性窦性心律失常 (RSA) 的时间过程。增长模型测试了 RSA 动态模式的上下文差异和相关性。任务之间的动态模式不同，并且根据母亲对幼儿害羞的看法和痛苦而有所不同。因此，
