A Simple Technique for Auto-Shaping Lever Pressing by the Rat Within a Single Session

Abstract

9 rats were exposed to a simple technique for auto-shaping magazine approach and lever pressing. 60 food pellets were presented noncontingently during magazine training at a fixed time of 60 sec. with levers covered. Lever covers were removed and rats were provided access to pellets on a Continuous Reinforcement Schedule (CRF). All Ss acquired magazine approach and lever-pressing behavior during the first session, earning 90 pellets on a CRF schedule within 17–34 min. after exposure to the lever.
