Abstract
Two albino rats were given extensive discriminated escape training where a leverpress on a VR-5 schedule produced an auditory SD, in the presence of which a pigeon key response terminated a light and brief shock. Following leverpress extinction, Ss received either the SD or a neutral SN on a VI-5 schedule, but no escapes. Each of the four tests involving SD for each S showed greater R reacquisition than for SN tests, demonstrating that the SD functioned as a secondary positive reinforcer.
