Differential eyelid conditioning as a function of the probability of reinforcement of the conditioned stimuli

Abstract

Differential eyelid conditioning was investigated with different schedules of reinforcement of CSI and CS2. The reinforcement schedules employed were 100%-0%, 80%-0%, 100%-20%, and 80%-20%. Significant differentiation occurred in all groups. With the reinforcement schedule to CSI constant at 100%, increasing the reinforcement schedule from 0% to 20% resulted in a decrease in responding to CSI. With reinforcement schedule of CS2 constant at 0%, decreasing the reinforcement schedule of CSI from 100% to 80% resulted in increased responding to CS2. A stimulus generalization interpretation was offered.
