Studied the heart rates of 48 male undergraduates who either responded as rapidly as possible following the termination of an extended visual warning or merely observed the same temporal sequences of nonsignal visual stimuli. In the RT groups (a) following the onset of the warning signal, heart rate variability increased;(b) in anticipation of the termination of the preparatory interval (PI), heart rate variability decreased; and (c) following the onset of the respond signal, both heart rate and heart rate variability increased. In the control groups, there were no significant changes in either heart rate or heart rate variability. In the RT group presented with a schedule of variable PIs, the mean magnitude of heart rate variability reduction in anticipation of the termination of the PI and the mean pretrial heart rate variability were significantly correlated with RT. When the PI was of a fixed duration, the heart rate variability measures were not significantly related to RT.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
