Population
104 young and healthy participants
I
Intervention
Assessment of resting-state vagally mediated heart rate variability (vmHRV)
O
Outcome
Intraindividual reaction time variability (IIV) during an attentional (target detection) tasksurrogate
Resting vagally mediated heart rate variability is a significant predictor of intraindividual reaction time variability, providing evidence for a link between resting vmHRV and cognitive control.
