Abstract
We describe a novel, brief evaluation of the effects of nonremoval of the cup on the consumption of water in a boy with autism and liquid refusal associated with a feeding disorder. The evaluation demonstrated that nonremoval of the cup, added to noncontingent reinforcement, increased water consumption compared to noncontingent reinforcement alone. This finding replicates prior research and provides practitioners with a brief experimental method for quickly determining a client’s responsiveness to nonremoval of the cup.
