Health decisions based on emotional impulses in conditions of uncertainty.

This experimental study analyzes how uncertainty influences health-related decision making by increasing reliance on affective impulses. Using a randomized pre–post design with an induced uncertainty condition based on false cardiac feedback, the research examines physiological activation, decisional conflict, and affect-based choices. Results indicate that uncertainty enhances affect-driven decision making, highlighting the role of emotional processes in health-related judgments under ambiguous conditions.
