Abstract
The current study assessed the effects of the type A behaviour pattern and family history of hypertension on cardiovascular (pulse amplitude heart rate and blood presssure), behavioural and subjective components of stress response. With this aim, 100 subjects (50 male and 50 female) participated in two control vs. noncontrol experimental conditions. In comparison with type B, type A individuals showed a greater pulse amplitude in both conditions. Subjects who had a reported family history of hypertension had a greater heart rate reactivity, while the systolic blood pressure was affected by the interactions between type A behaviour pattern and family history. Finally, cardiovascular, behavioural and subjective components of stress response supported the hypothesis of control motivation.
