Resumo
Key pecking by two pigeons, maintained under a variable‐interval two‐minute schedule of food presentation, was suppressed when each response produced a five‐second visual stimulus that was occasionally paired with shock. Stimulus‐shock pairings occurred independently of responding according to a variable‐time six‐minute schedule for one bird or once per session for the other bird. The effects of chlordiazepoxide and d‐amphetamine were assessed on this baseline of behavior suppressed by conditioned punishment. Chlordiazepoxide produced dose‐related increases in the rate of punished responding, whereas d‐amphetamine produced only decreases. In addition, chlordiazepoxide produced dose‐related increases in response rate during the response‐produced and response‐independent stimulus presentations; d‐amphetamine, however, only decreased responding during stimulus presentations.
