Using Graduated Exposure and Differential Reinforcement to Increase Food Repertoire in a Child with Autism.

Food selectivity is often seen in children with autism spectrum disorder and can lead to severe nutritional deficiencies. Food selectivity can be specific to food texture, colour, shape, presentation, type, brand or container. Often food selectivity is treated using escape extinction in conjunction with other procedures, which can be challenging to implement for the therapist or caregiver, aversive for the child, and requires adequate supervision from a professional to ensure fidelity of the procedure.
