INTERACTIVE INFLUENCE OF SELF-REPORTED ABILITY AND AVOIDANT TASK DEMAND ON ANTICIPATORY CARDIOVASCULAR RESPONSIVITY

This study was conducted to further examine the role that perceptions of ability may play in determining the impact of task demand on cardio vascular responses associated with active coping. Subjects who describ ed themselves as having low or high ability in math were given the opp ortunity to avoid a noise by doing well on a set of math problems desc ribed as easy (Low Demand), difficult (High Demand), or extremely diff icult (Very High Demand). Measures taken immediately prior to the perf ormance period indicated that systolic blood pressure reactivity (a) w as greater in the High Demand condition than in the Low and Very High Demand conditions for those with low reported ability, but (b) tended to increase with the level of task demand for those with high reported ability. Moreover, whereas systolic responsiveness tended to be great er for Low Ability subjects than for High Ability subjects when task d emand was low and was greater for Low Ability subjects than for High A bility subjects when task demand was high, it tended to be greater for High Ability subjects than for Low Ability subjects when task demand was very high. These findings conceptually replicate and extend effect s observed previously and provide additional support for a conceptual analysis which suggests that active coping is a joint function of perc eived ability and task demand.
