Several studies have suggested that reaction time (RT) may be related to variations in blood pressure which occur with each heart beat. This was tested in a series of four studies in which possible effects of the preparatory interval (PI) were controlled. Stimuli were presented at 0, 200, 400, and 600 msec following the R wave, and during the ascending slope of the R, T, and P waves of the cardiac cycle. No relationship was found in any of the four studies between RT and the phase within the cardiac cycle when the stimulus occurred.
