Study Summary

Developing theoretical, quantitative models of the basic cognitive mechanisms underlying human social decision-making, and understanding the influence of neuromodulators such as dopamine on these mechanisms, has important ramifications for both healthy and patient populations. In this proposal the investigators combine quantitative social measures, computational models, neuroimaging, and a pharmacological intervention to define the mechanisms of social decision-making.

Primary Outcome

Subjects will make financial decisions involving themselves and another person in the context of model-based neuroeconomic games.

Interventions

  • OTHER Functional Magnetic Resonance Imaging (fMRI)
  • DRUG Tolcapone 200 MG
