Recent research findings suggest that low preference stimuli can be effective reinforcers. This study compared responding to high preference and low preference stimuli under continuous reinforcement. Results demonstrated that responding was greater when a high preference stimulus was presented. Other research findings suggest that stimulus variation increases the potency of reinforcers perceived to be of high preference. This study extended this line of research by evaluating whether stimulus variation would increase the potency of low preference stimuli. Results demonstrated that when three low preference stimuli were presented in a varied fashion, responding corresponded with the levels obtained when a high preference stimulus was presented. Furthermore, a varied reinforcer presentation of low preference stimuli was found to increase and maintain high percentages of correct responding and on‐task behavior to levels equal to those obtained with a high preference stimulus during a discrete trial preparation.
