Key result
Type A subjects exhibited significantly greater systolic blood pressure and pulse pressure elevations than Type B subjects during a cognitive task, regardless of incentive conditions.
Why the study?
Does a monetary incentive alter the behavioral and cardiovascular responses to a cognitive task in individuals with Type A versus Type B behavior patterns?
Population
44 subjects of the Type A (coronary-prone) and Type B (non-coronary-prone) behavior patterns
Comparison
Performance-contingent incentive during a… vs No incentive during the same cognitive task
Design
Other, Assigned to one of two task conditions

Supports Type A association with exaggerated BP responses to cognitive stress; hypothesis-generating and should not yet change practice.
Does a monetary incentive alter the behavioral and cardiovascular responses to a cognitive task in individuals with Type A versus Type B behavior patterns?
Type A behavior pattern is associated with exaggerated systolic and pulse pressure responses to cognitive tasks, independent of monetary incentives.
Manuck et al. (1979) studied Type A and Type B behavior patterns (n=44). Performance-contingent incentive (monetary reward) vs. No Incentive was evaluated on Behavioral and cardiovascular responses to a difficult cognitive task. Type A subjects exhibited significantly greater systolic blood pressure and pulse pressure elevations than Type B subjects during a cognitive task, regardless of incentive conditions.
