- Abstract
Stimulus preference assessments often include items suspected to be highly preferred. If only high-preference stimuli are assessed, preference hierarchies may not accurately predict the results of reinforcer assessments (RA). In this study, paired-stimulus (PS) preference assessments using items suspected to be preferred (PS-1) generated distinct preference hierarchies. Subsequent RAs (RA-1) indicated that high-preference and low-preference stimuli were associated with similar response rates. Additional assessments (PS-2) were then conducted, using the least-preferred item from PS-1 plus seven new stimuli. The least-preferred items on PS-1 ranked as most preferred on PS-2, and on RA-2, the top-ranked items functioned as reinforcers, but low-ranked items did not. Implications for incorporating low-preference items into clinical/educational programming are discussed. Copyright © 2011 John Wiley & Sons, Ltd.
