The behavior of four monkeys trained on a multiple schedule was differentially sensitive to selected pharmacological agents. The three components of the multiple schedule were: (1) a variable‐interval schedule in which responses were reinforced on the average of once per minute; (2) a concurrent schedule in which every tenth response was reinforced and every fifteenth response, on the average, was shocked; and, (3) a neutral stimulus in the presence of which responses were neither reinforced nor shocked. Pentobarbital, chlordiazepoxide, and meprobamate increased responding during each of the components. Scopolamine and d‐amphetamine decreased variable‐interval performance, had minimal effects on performance during the concurrent‐schedule component, and increased responding in the presence of the neutral stimulus. Chlorpromazine decreased variable‐interval responding and had slight effects on the responding during the other two components.
