Abstract:
Children with feeding disorders may pack food (i.e., hold food in the mouth for a prolonged period of time). Treatments to target packing exist, including reinforcement contingencies, redistribution, and chasers, but these strategies are not always effective. Simultaneous presentation has also been used to reduce packing; however, it has not been faded out. The current study expanded this literature by using a treatment package, which included simultaneous presentation, to decrease packing in a 4-year-old boy with autism and food selectivity who packed nonpreferred foods. The simultaneous presentation component was then systematically faded out until generalization occurred.
