Conditioned reinforcement of lever-pressing in rats by a brief stimulus and schedule of primary reinforcement

Abstract A stimulus controlling terminal component responding in a chained schedule was presented briefly after responses in the initial component on a variable-interval schedule, without subsequent primary reinforcement, under conditions in which, rate in the initial component was low, and rate inc...

Abstract A stimulus controlling terminal component responding in a chained schedule was presented briefly after responses in the initial component on a variable-interval schedule, without subsequent primary reinforcement, under conditions in which, rate in the initial component was low, and rate increased. The reinforcing capacity of the stimulus was greater with CRF in the terminal component than with FI 2-min and was not affected by substitution of a DRO contingency for CRF. Ausführliche Beschreibung
