76 BP (40 females, 18 unmedicated), 132 SZ (41 females, 19 unmedicated1), and 136 NC (76 females) participated in the study. Table 1 presents demographic, medication, and clinical information. NC were recruited by public advertisements, and patients were recruited through physician referrals. Exclusion criteria included serious head injury (with loss of consciousness > 5 minutes), neurological disorders, and intoxication (either drug or alcohol use assessed via urine screen) at the time of testing. NC were free of Axis I disorders, did not have a first-degree biological relative with either schizophrenia or bipolar disorder, and were not taking psychotropic medication. All participants provided written informed consent. This study was approved by the Indiana University Internal review board.
