Overview
Research in our lab examines how individual and age differences in motivation and cognition influence decision making across the life span. Our research is at the intersection of a number of subfields within psychology, neuroscience, and economics including human development, affective science, cognitive neuroscience, behavioral economics, and finance. We use a combination of behavioral and neuroimaging techniques ranging from detailed measurement of functional brain activity (fMRI) and neuroreceptors (PET) in the laboratory to experience sampling in everyday life.
