 In order to assess brain responses to outcomes, and cues predictive of outcomes, we will enroll 135 total participants SC patients and controls, aged 18 - 55. For a first set of experiments, we enrolled 54 total subjects 37 SCs and 17 controls to achieve 34 total completers 24 SCs and 10 controls. In a second set of experiments, our goal is to examine two types of SC patients those taking clozapine and those taking a different second-generation antipsychotic. For these experiments, we will enroll 81 total subjects 27 controls, 27 SCs taking clozapine, and 27 SCs taking a different second-generation antipsychotic to achieve approximately 47 total completers 15 controls, 16 SCs taking clozapine, and 16 SCs taking a different second-generation antipsychotic.
