The relationship between baseline response rate and the effect of presenting a stimulus followed by response-independent reinforcement on baseline response rate was investigated in this study. Six pigeons were divided into two equal groups, one of which was conditioned to key peck on a VI-DRH schedule of food reinforcement, the other on a VI-DRL schedule of food reinforcement. Once responding had stabilized, a tone was introduced seven times during each session followed by a response-independent food reinforcement. The results indicated no change in the response rate of the VI-DRH group during the tone, and acceleration of responding during the tone for the VI-DRL group.
