Abstract
The purpose of the present experiment was to demonstrate that the pattern of responding generated by an unsignaled differential-reinforcement-of-low-rate schedule (DRL) is a good predictor of the degree of stimulus control obtained when discriminative stimuli are introduced. The responses of 14 rats were first reinforced on an unsignaled DRL 25-sec schedule for 11 sessions. On Session 12 the schedule was changed to a signaled DRL 25-sec schedule for 11 sessions. The degree of stimulus control acquired by the added discriminative stimuli was inversely related to the efficiency ratio calculated from the unsignaled performance.
