Title:
A Computational Approach to Affect and Decision Making

Abstract:
This research investigates how stress and arousal influence decisions under uncertainty. Two initial studies examine the effect of acute arousal and stress on risk and ambiguity aversion. The research highlights the role of the timing of arousal, suggesting that emotions synchronized with decision moments may significantly alter choice outcomes.A third study explores the long-term impact of early-life stress on decisions involving anticipated regret. By analyzing choices in scenarios where future regret is weighed, the research suggests that individuals with a history of stress may prefer options that minimize potential negative outcomes, indicating a deep-seated inclination to avoid regret. Collectively, these findings illuminate the complex interplay between psychological states and decision-making, revealing both immediate and lasting influences of stress and arousal on how choices are made and preferences are formed.
