Abstract:
Reliability of heart-rate reactivity responses to a timed and competitive mental arithmetic stressor was investigated in a sample of 40 students. Analysis indicated that significant differences between groups of high and low heart-rate reactivity subjects were consistent over a period of 4 to 6 wk., with no significant effects from mental arithmetic performances.
