Effects of haloperidol and D-amphetamine on choice behavior and time to complete a trial. A. Pretreatment with saline and treatment with D-amphetamine (0.75 mg/kg) increased the number of trials to choose the SR arm in a comparison with all other regimens, as indicated by the single asterisk. Pretreatment with haloperidol (0.1 mg/kg) and treatment with saline decreased the number of trials to choose the SR arm in comparison to all other pretreatment/treatment regimens as indicated by the two asterisks. B. Pretreatment with haloperidol significantly increased the time to complete each trial in comparison to pretreatment with saline, as indicated by the asterisk. Data represent mean ± S.E.M. n = 9.
