• Have a Full Scale IQ score >80.
• Smokers will meet DSM-IV criteria for nicotine dependence, and smoke at least 15 cigarettes per day, with an FTND score at baseline >5, breath CO >10, and plasma cotinine >150 ng/ml.
• Nonsmokers will report a history of never smoking (<100 cigarettes lifetime) or be abstinent from smoking for at least 6 months prior to randomization, with abstinence biochemically confirmed by CO level <10 ppm and plasma cotinine <15 ng/ml.
• Schizophrenic subjects will meet DSM-IV criteria for schizophrenia or schizoaffective disorder, and be on a stable dose of antipsychotic medication for at least three months, with positive symptoms stability as judged by the investigator.
