Key result
Executive control was associated with vagal modulation of high-frequency heart-rate variability (p<0.03), and motivational control with sympathetic modulation of low-frequency HRV (p<0.03).

Executive and motivational control are distinctly associated with vagal and sympathetic modulation of heart rate variability in children, supporting a two-factor model of inhibitory control.
Supports two-factor inhibitory control model via distinct HRV patterns in children; hypothesis-generating, needs longitudinal data before clinical relevance.
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.

Mezzacappa et al. (1998) reported a cross-sectional. Physiologic challenges (paced breathing and postural change) was evaluated on Association of executive and motivational control with heart-rate variability (p=< .03). Executive control was associated with vagal modulation of high-frequency heart-rate variability (p<0.03), and motivational control with sympathetic modulation of low-frequency HRV (p<0.03).
