I study affect and decision-making. Classic theories describe the influence of affect as "hot", automatic, and often irrational, in opposition to "cold," controlled, rational cognition, but this simplistic dichotomy ignores the complexity of both affect and decision-making. My research combines computational behavioral models of value and learning with psychological theories of affect and self-regulation, and measures and manipulations of components of emotion and the brain. By leveraging psychology, economics, and neuroscience, I seek to develop a more nuanced, sophisticated understanding of affect and decision-making.My approach is captured in two main goals: first, to identify specific links between unique components of affect and specific decision processes, and second, to understand how techniques used to change emotions can be used to change choices.
