Depression, Aging, Stress and Heart Health Study

The TSST has both social-evaluative and arithmetic components. During the social-evaluative component, the participant is asked to prepare and then deliver a brief speech to the research team. After this component there is a surprise arithmetic problem. This challenge paradigm has been well-established to rapidly and robustly induce psychological stress as well as physiological indices of stress (e.g., cortisol response, heart rate response). This task takes approximately 15 minutes to complete.
