Forty-two (42) children (mean age 10.6 years) from mainstream public (N = 22) and therapeutic schools (N = 20) completed performance tasks assessing executive and motivational influences on motor responses. In a separate protocol, children underwent physiologic challenges of paced breathing and supine to standing postural change, while heart rate was continuously monitored. Executive control was associated with vagal modulation of respiratory driven, high-frequency heart-rate variability (t = 2.20, p < .03), whereas motivational control was associated with sympathetic modulation of posturally driven, low-frequency heart-rate variability (t = -2.22, p < .03). These findings supported a two-factor solution of inhibitory control derived in a previous study.
来自主流公立学校（N = 22）和治疗学校（N = 20）的42名儿童（平均年龄10.6岁）完成了评估执行和动机对运动反应影响的表现任务。在另一个方案中，儿童接受了有节奏呼吸和仰卧到站立姿势变化的生理挑战，同时持续监测心率。执行控制与呼吸驱动的高频心率变异性的迷走神经调节有关（t = 2.20，p <.03），而动机控制与姿势驱动的低频心率变异性的交感神经调节有关（t = -2.22，p <.03）。这些发现支持了先前研究中得出的抑制控制的双因素解决方案。
