Abstract
Changes in heart rate (HR), heart rate variability (HRV), blood volume pulse (BVP), respiration speed (RS) and alpha rhythm (AR) were studied under conditions of the variation of the speed and intervals of auditory stimuli in a serial two-choice response task. The analysis of variance of the percentage scores revealed that the differences between the three speed levels (condition B), the five physiological variables (condition C), and also the second-order interaction between the speed of presentation and the physiological variables were significant. The difference between the interval variation levels (condition A) was not significant. The short-term effect of step-wise variation of the duration of intervals between successive stimuli on physiological change was also investigated and an explorative study was made of the periodic fluctuations of three physiological variables by applying the techniques of auto-correlation and power spectrum analysis.
