Abstract:
Previous research has demonstrated that extinction in the form of re-presentation of expelled bites is an effective intervention for treating food expulsion. The current study compared the effectiveness of re-presenting expulsions with a spoon to re-presenting with a Nuk brush for a 4-year-old boy with a feeding disorder. Fewer expulsions were observed when using the brush for re-presentation, and further reductions were observed when the brush was also used for initial presentations.
