Classic dual-process theories of emotion and decision-making characterize emotion as a “hot,” irrational force, in opposition to “cold” cognition. Recent work in the neuroscience and psychology of emotion has challenged this view, suggesting instead that the relationships between emotion and cognition across domains are best characterized as specific and modulatory. I will present a series of studies in the domain of risky monetary decision-making identifying one such specific, modulatory role of emotion, namely in driving the overweighting of losses relative to gains, called “loss aversion”. Across studies using a variety of methods including econometric models to quantify and dissociate different decision-making processes, physiological measures of arousal, neuroimaging, emotion regulation techniques, and pharmacological manipulation, we find consistent and causal evidence for a modulatory noradrenergic amygdala-based system that selectively drives loss aversion (and not other processes like risk attitudes or choice consistency).
