Treatment of Food Selectivity: An Evaluation of Video Modeling of Contingencies

The purpose of this study was to evaluate the effectiveness of video modeling of contingencies alone and/or combined with direct exposure to the contingencies in the treatment of food selectivity. Treatment procedures included sequentially introducing videos in which models consumed nonpreferred food, were exposed to differential reinforcement, or exposed to escape extinction and differential reinforcement. In addition, participants were exposed to differential reinforcement. Results indicated video modeling of differential reinforcement plus differential reinforcement may be effective at increasing consumption of some nonpreferred foods, but the results were not replicated across all foods. For one participant, consumption of one food increased with video modeling alone
