This study employed piecewise growth curve modeling to examine how children's executive function (EF) skills relate to different components of children's physiological response trajectory - initial arousal, reactivity, and recovery. The sample included 102 ethnically diverse kindergarteners, whose EF skills were measured using standard tasks and observer ratings. Physiological response was measured via changes in respiratory sinus arrhythmia (RSA) in response to a laboratory socio-cognitive challenge. Children's cool and hot EF skills were differentially related to both linear and quadratic components of RSA response during the challenge. Greater hot EF skills and assessor report of EF skills during laboratory visit were related to quicker RSA recovery after the challenge. These findings demonstrate that children's physiological response is a dynamic process that encompasses physiological recovery and relates to children's self-regulation abilities.
本研究采用分段增长曲线建模来研究儿童执行功能（EF）技能与儿童生理反应轨迹的不同组成部分（初始唤醒、反应性和恢复性）之间的关系。样本包括 102 名种族多样化的幼儿园儿童，他们的 EF 技能通过标准任务和观察者评分来衡量。生理反应通过呼吸窦性心律失常（RSA）在实验室社会认知挑战中的变化来衡量。在挑战期间，儿童的冷静和热情 EF 技能与 RSA 反应的线性和二次成分都存在差异。更强的热情 EF 技能和实验室访问期间的 EF 技能评估与挑战后 RSA 恢复更快相关。这些发现表明，儿童的生理反应是一个动态过程，包括生理恢复，并与儿童的自我调节能力相关。
