There will be a significant diagnosis by drug administration of 0.3 mg of oral pergolide interaction for performance on the cognitive tasks, with the schizotypal personality disorder group demonstrating significantly improved peformance compared to the other personality disorder group after pergolide compared with placebo.

Design: Randomized, double-blind, crossover study of pergolide vs. placebo. Half of subjects receive pergolide for eight weeks; half of subjects receive placebo for four weeks followed by pergolide for four weeks.
