Central auditory processing disorders and reduced motivation: three case studies.

The central auditory test results for three normal-hearing children who were initially diagnosed as having a central auditory processing disorder and learning disability are presented. They were referred to the authors for second-opinion consultations. Central auditory processing retesting was performed by the authors under the condition of no reinforcement and then the condition of reinforcement with the child's favorite food, hobby, or toy. For all three cases, the central auditory test scores improved markedly bilaterally under the condition of reinforcement as compared with the condition of no reinforcement. We hypothesize that the improvement was related to increased motivation associated with the reinforcement and that these children represented false-positive results on the central auditory test battery. Large-sample studies are needed to investigate the effect of reinforcement on test performance in children with reduced central auditory test scores.
