Expulsion (spitting out food) is a problem behavior observed in many children with feeding disorders. In the current investigation, we identified 4 children diagnosed with a feeding disorder who exhibited high rates of expulsion. Treatment with re-presentation (placing expelled liquids or solids back into the child's mouth) was not effective in reducing expulsion. Therefore, we added a chin-prompt procedure (the feeder applied gentle upward pressure to the child's chin and lower lip) for the initial presentation and the re-presentation. Chin prompt plus representation resulted in low rates of expulsion for all 4 children. The results are discussed in terms of the potential underlying mechanisms behind the effectiveness of the chin-prompt procedure.
