A METHOD FOR INCREASING THE REINFORCEMENT MAGNITUDE OF INTRACRANIAL STIMULATION1

Abstract

Schedules of intermittent brain-stimulation reinforcement have been shown to maintain performances when a reinforcement is defined as several response-produced, brief trains of stimulation. The present experiments show that the number of response-produced trains permitted per reinforcement is a variable analogous to amount or magnitude of reinforcement in the conventional food-reinforcement experiment. Systematic effects were obtained when that variable was manipulated within a multiple schedule and also on variable-interval schedules programmed concurrently.
