Research Program Summary
How is it that a depressed individual may value nothing at all, whereas an addict might value drug consumption at the expense of all else? What quantitative neurobehavioral measures of motivation, social function, and emotion may be useful for clinical assessment? What makes some people especially vulnerable to peer pressure?
To address these and related questions, the lab examines the neurobiology of human motivation and social decision-making. Our work focuses on how such processes may be perturbed and rehabilitated in psychiatric populations.
Ongoing projects use multiple converging methods (e.g., behavior, self-report, clinical interviews, computational models, fMRI) to: 1) identify neural circuitry involved in healthy decision-making; 2) specify how these pathways go awry in clinical populations marked by deficits in valuation and motivation (e.g., major depression, addiction, PTSD, autism); and 3) develop biologically-informed interventions to remediate these functional deficits.
