Abstract
A discriminated escape procedure was employed to train two groups of rats to activate a nose press in the presence of a tone to escape a 1-mA shock. Escape was allowed on a continuous or an intermittent schedule. Each group was then divided into three subgroups, two of which were required to learn a leverpress response where the only reward was the tone, presented on a continuous or an intermittent reinforcement schedule. The third subgroup served as a no-tone control. A durable secondary reinforcer was established which was a function of the secondary reinforcement schedule during testing.
