Why the study?
Does task difficulty affect cardiac reactivity (preejection period, heart rate, and blood pressure) during active coping?
Does task difficulty affect cardiac reactivity (preejection period, heart rate, and blood pressure) during active coping?
The study provides evidence that energy mobilization in active coping is mediated by beta-adrenergic impact on the heart, as cardiac reactivity increases with task difficulty until success becomes impossible.

Hypothesis-generating for beta-adrenergic mediation of coping effort; leaves open clinical translation to stress testing.
