Abstract
Rats were trained to respond to avoid a brief electric shock on a schedule of adjusting avoidance. After a stable baseline was established, differential response-contingent shock was superimposed onto the schedule. Although response rates and shock density remained unchanged, rats were able to avoid the punishment shocks. This finding contradicts previous work on the ability of rats to discriminate their position in a schedule of adjusting avoidance.
