Three functional assessments of a client with self-injurious behavior (SIB), indicated that SIB was sensitive to attention as reinforcement and was much higher when the client was in his wheelchair. Levels of SIB remained higher when the client was in his wheelchair, even when consequences for SIB were identical. (Author/CR)

Three severely mentally retarded adolescents who exhibited repetitive hand movements were assessed during baseline (reinforcement for on-task behavior) and sensory change (rings on fingers of both hands, rings and reinforcement, and faded rings) conditions. Sensory change effectively reduced the target responses for up to four hours. (Author/JDD)

A study developed a systematic functional assessment package to reduce the stereotypy and self-injurious behaviors maintained by nonsocial reinforcement in two individuals with mental retardation. Differential reinforcement of zero rates of responding (DRO) procedures using stimuli within the targeted sensory classes were successful in eliminated…
