Abstract
The effects of drug were studied on responding punished with various intensities of electric shock. Morphine did not increase punished responding at any shock intensity. Chlorpromazine increased punished responding only when the dose was very large and only when the shock markedly suppressed responding. Pentobarbital and diazepam produced large increases in the rate of punished responding. These increases in punished responding depended on the shock intensity and on the control rate of responding.
