The work of Duke neuroscientist Scott Huettel has shown, what mechanisms shape human decision making. Few things are more personal than the choices we make. Each of us is continually faced with a wide range of decisions - from the mundane to the impossibly complex - whose resolution shapes the course of our lives. Yet, how we make decisions remains one of the major unanswered problems in cognitive psychology, behavioral economics, and cognitive neuroscience. This is also the cardinal research topic within the emerging discipline of neuroeconomics.
