The present study examined the association between behavioural dimensions of self‐regulation and respiratory sinus arrhythmia (RSA), a marker of cardiac autonomic functioning in a sample of preschool children in the United States. Sixty‐six children’s emotion‐ and cognitive‐oriented dimensions of self‐regulation were examined with respect to changes in RSA (reactivity and recovery). Results showed that children’s recovery RSA, which indicates the ability to return to homeostasis, but not reactivity, was significantly associated with the cognitive‐oriented self‐regulation.

探索学龄前儿童自我调节维度与心脏自主神经功能的关系

本研究调查了自我调节的行为维度与呼吸性窦性心律失常 (RSA) 之间的关联，RSA 是美国学龄前儿童样本中心脏自主神经功能的标志物。根据 RSA（反应性和恢复）的变化，检查了 66 名儿童的情绪和认知导向的自我调节维度。结果表明，儿童的恢复 RSA 表明恢复稳态的能力，而不是反应性，与以认知为导向的自我调节显着相关。
