Abstract Rationale. The relative reinforcing strength of cocaine can be characterized by the distribution of operant behavior during the availability of other reinforcing stimuli. Objective. To develop a procedure to rapidly evaluate the relative reinforcing strength of cocaine in monkeys. Methods. Monkeys were trained to respond on two levers under concurrent fixed-ratio 30 (FR30) schedules of reinforcement. Responding on one lever resulted in food delivery, responding on the alternative lever… CONTINUE READING
