 Methods- Up to 25 volunteers with schizophrenia and 25 volunteers without a psychiatric disorder will participate in this study at the Atlanta VA Medical Center. Subjects will first be interviewed about their medical and psychiatric history, and any current symptoms they are having. They will receive an fMRI scan during which they will play a computer game that rewards correct responses with money. This fMRI session will allow for the assessment of which parts of the brain are functioning during rewarding conditions. The results will be compared for subjects with and without schizophrenia.
