摘要

Recent studies have shown that moderate (Piazza, Fisher, Hagopian, Bowman, & Toole, 1996) and low (Taravella, Lerman, Contrucci, & Roane, 2000) ranked items on stimulus preference assessments may function as reinforcers. Following an initial preference assessment the current study analyzed whether moderate or low preference items were more likely to be ranked as high preference on subsequent preference assessments. Results show that for five of the seven participants additional high preference items were identified from the moderate preference set, while additional high preference items were identified from the low preference set for only one participant. Results are discussed in terms of the need to identify multiple reinforcers and the composition of the stimulus array during preference assessment. Copyright (c) 2006 John Wiley & Sons, Ltd.
