There are several studies and hypotheses to be tested. This project includes a cross-sectional study design measuring brain waves, clinical symptoms, cognitive and functional ability, and genetic information in schizophrenic patients and normal controls. Subjects are expected to do a brain wave recording (EEG/ERP), role-play test designed to measure functionality and cognitive ability, and clinical symptom assessments. Expected duration of subject participation will be approximately 8 hours (about 2 visits). Outcome measures includes biomarkers, clinical symptoms and function, and genetic information.
