Summary
The effects of amobarbital and chlorpromazine were studied on punished behavior in the pigeon. Key-pecking responses, maintained by a variable-interval schedule of food reinforcement, were punished by brief electric shocks. Under this simultaneous food and punishment schedule, responding is suppressed and occurs at a fairly uniform rate that is inversely related to the punishment intensity. Amobarbital partially restores responding suppressed by punishment, but chlorpromazine has no tendency to attenuate suppression by punishment.
