Children with developmental delay are more likely than their typically developing peers to experience emotional dysregulation. Given that there is evidence that respiratory sinus arrhythmia (RSA) reactivity indexes emotion regulation, which in turn tracks motor, language, and cognitive development across the early years, RSA reactivity should develop accordingly in that period and differ by developmental status. The present study therefore compared those with and without developmental delay (across adaptive, personal-social, and motor domains) on the growth in RSA reactivity in the preschool years (ages 3-5 years) across three time points. Results showed that those with global developmental delay exhibited atypical RSA reactivity progression (e.g., excessive or insufficient vagal withdrawal) across the preschool years. Follow-up is needed to determine whether this pattern of RSA reactivity persists later in childhood.
发育迟缓的儿童比发育正常的同龄人更有可能出现情绪调节障碍。鉴于有证据表明呼吸性窦性心律不齐（RSA）反应性可反映情绪调节，而情绪调节又与早年的运动、语言和认知发展相关，RSA反应性在这一时期应相应发展，并因发育状况而异。因此，本研究比较了有和没有发育迟缓（在适应性、个人社交和运动领域）的儿童在学龄前（3至5岁）三个时间点的RSA反应性增长情况。结果显示，患有全面发育迟缓的儿童在整个学龄前阶段表现出非典型的RSA反应性进展（例如，迷走神经撤离过度或不足）。需要进行随访以确定这种RSA反应性模式在儿童后期是否持续存在。
