A two‐part experiment was conducted in which a youth who was diagnosed as severely learning disabled was treated for a lack of reading and math skills. Token reinforcers were delivered for correct responses to a structured set of math problems and sight words. The subject reached a 90% correct response rate following implementation of a changing criterion experimental design. Part two of the study produced a 100% achievement level for the most difficult multiplication and division items. Results imply that some behaviors identified as learning disabilities may be treatable using motivational strategies.
