The relationship between the Type A Behaviour Pattern and heart‐rate reactivity to the onset of a typical stressor was investigated with a sample of Australian boys and girls from three age‐grade levels: preschool, middle‐elementary, and upper‐elementary. Behaviour Pattern was measured with the Matthews Youth Test for Health (Matthews & Angulo, 1980), and data were collected on children's second‐by‐second heart rate during rest and the stressor tasks. Reactivity to the onset of the stressor task (a puzzle game or mental arithmetic), was assessed. Results indicated that there were expected age differences in resting and stressor task heart rates, but that there was no significant difference in heart‐rate reactivity between children classified as Type A or B Behaviour Pattern, either for the entire sample, for two extreme subsamples, or within each of the three age groups.
