Abstract

Three experiments with rat subjects examined the effects of a context switch after conditioning treatments in which the conditioned stimulus (CS) waseither paired with food on every presentation (continuous reinforcement) or on some of its presentations (partial reinforcement). In each experiment,a target CS was given one of these treatments in Context A, and another CSwas given a treatment during sessions that were intermixed in Context B. Final tests of the target CS in Context A and Context B often revealed no loss of responding with the switch to B. However, a loss was observed when partial reinforcement had been associated with Context A and continuous reinforcement had been associated with Context B. Those conditions caused equal decrements in responding to partially reinforced and continuously reinforced targets. The results suggest that under the present conditions partial reinforcement can generate a contextual stimulus that becomes associated withthe physical context and controls responding to the CS.
