The effects of d ‐amphetamine on punished responding were studied in two experiments. In Experiment I, pigeons responded under a multiple fixed‐ratio 30 response fixed‐interval 5‐min schedule of food presentation with 60‐sec limited holds in both components. Each response was punished with electric shock, the intensity of which was varied systematically. In Experiment II, another group of pigeons responded under a multiple fixed‐interval 5‐min fixed‐interval 5‐min schedule of food presentation with 40‐sec limited holds. Each response was punished with shock during one component, and every thirtieth response was punished in the other component. d ‐Amphetamine increased overall rates of punished responding only rarely under any of the punishment conditions; however, response rates within the fixed‐interval when rates were low were increased by d ‐amphetamine when the shock intensity was low (Experiment I), or when responses produced shock intermittently (Experiment II). The data suggest that the effects of d ‐amphetamine on punished responding depend on the control rate of responding, the punishment intensity, the punishment frequency, and the schedule of food presentation.
