A further refinement of procedures addressing food selectivity

Individuals with autism and/or developmental disabilities are more likely than their typically developing peers to be food selective. Evidence‐based treatment packages for food refusal and selectivity include the use of reinforcement, escape extinction, and manipulation of antecedent events .

A changing criterion design was used to systematically increase the expectation of the amount and variety of foods that were consumed.
