Abstract
The effects of contingent pairing of highly-preferred leisure items with low-preferred food items on snack selection of kindergarten-aged students with disabilities was evaluated in an A-B-A-B withdrawal design. Food and leisure preferences were assessed through three different multiple-stimulus without replacement (MSWO) assessments: Food items alone, leisure items alone, and a combined food and leisure. Baseline data were collected by presenting the low-preferred food item beside the highly-preferred food item and allowing the participant to select one. During intervention, the highly-preferred leisure item was paired contingently with the low-preferred food item and the participant was allowed to select one. For one participant changes in snack selection were observed and for the second participant no changes in behavior were observed. Following modifications to the procedure, immediate changes were observed in the third participants behavior and were replicated across the A-B-A-B conditions. Each participants data are discussed as well as limitations of the study.
