Running Head: Chang & Sanfey - Emotion and Decision-Making Emotion, Decision-Making and the Brain

The burgeoning field of neuroeconomics integrates principles from the fields of psychology, economics, and neuroscience to understand the mechanisms underlying choice behavior. Initial explorations have highlighted evidence supporting a potential dissociation between a fast automatic system and a slow deliberative controlled system. This notion has received previous attention in the judgment and decision-making literature. Growing research in the role of emotion in decision-making has attempted to draw parallels to the automatic system, which scholars have even likened to an " irrational " system. This paper will discuss a theoretical framework for understanding the role of emotion in decision-making and evidence supporting the underlying neural substrates.
