This study compared the effects of unequal and equal reinforcer duration during a functional analysis of aberrant behavior in an 11-year old with moderate mental retardation. Results showed that reinforcer duration affects the rate of aberrant behavior and may potentially alter functional analysis interpretation. (DB)

Noncontingent reinforcement (NCR) was applied to reduce the destructive behaviors of five-year-old quadruplets diagnosed with mental retardation and pervasive developmental disorder. Findings suggest that the effectiveness of NCR may be dependent on the use of a dense schedule of reinforcement initially and that systematic fading can increase the…

We used functional communication training to teach Bob, a 10-year-old student with autism and severe language delays, to reject items by touching an icon. Our initial assessment revealed that Bob's behaviours serving a rejecting function consisted of pushing away, yelling, bear hugging-grabbing, and leaving. We used prompting, differential…

This study compared types of differential reinforcement of other behavior (DRO), namely, reward DRO (reward for omission of problem behavior), escape DRO (termination of instruction contingent on omission of problem behavior), and combined DRO. The combined DRO approach was most effective in reducing behavior problems of three adolescents with…

A functional assessment of tantrum behaviors of two students (ages seven and nine) with severe mental retardation found that the function of the behavior was to gain attention rather than to avoid or escape demands. Intervention, based on the positive reinforcement hypothesis, resulted in a substantial reduction of tantrums for both subjects.…

This study of five young children with developmental delays or chronic health problems and with aberrant behaviors identified reinforcers that maintained aberrant behavior, used functional communication training to teach participants to gain reinforcement using mands, and implemented treatment involving choice making via manding. (JDD)

The study found significant improvements in behavior when a profoundly mentally retarded blind subject was reinforced with music. The young woman also discriminated among different types of music, and behavior rates varied accordingly. (Author/DB)

A simultaneous presentation procedure to select reinforcers was implemented with two four-year-old twin boys who were developmentally delayed, noncompliant, and mute. Use of the procedure quickly and efficiently identified preferred reinforcers which were then used in an instructional task. (DB)

This study compared the relative efficacy of providing simultaneous or delayed reinforcement on food acceptance during meals with a seven-year-old boy with pervasive developmental disorder and a history of food selectivity. Although both procedures were effective, the simultaneous reinforcement procedure produced more rapid behavior change and a…

This study compared rates of self-injurious behavior (SIB) exhibited by a 32-year-old woman with profound mental retardation across conditions in which access to restraint was either continuously available, presented as a consequence for SIB, or unavailable. Rates of SIB increased when access to restraint was contingent upon SIB, suggesting that…

Four studies analyzed eye poking behavior of a youth with profound disabilities. Results demonstrated substantive reductions in the frequency of eye poking when goggles were worn and when a video game was provided as a competing source of visual stimulation and as a reinforcer. Music was less effective in reducing eye poking. (Author/DB)

A behavioral consultation approach was effectively used to reduce problem behaviors in 2 field studies with 3 students (ages 10-14) having severe or profound mental retardation and their teachers. Intervention involved extinction of inappropriate behaviors, reinforcement of appropriate play behaviors, and teaching verbal skills functionally…

This study compared differential reinforcement of other behavior (DRO) and noncontingent reinforcement (NCR) in the reduction of self-injurious behavior in three adult females with severe or profound mental retardation. Both procedures were highly effective in reducing self-injury, with NCR less limited than DRO. (Author/DB)

Behavioral techniques (positive reinforcement and nonexclusionary timeout) effectively decreased problem behaviors of noncompliance and aggression of a young adult male with severe mental retardation and Down's syndrome residing in the community. (DB)

Functional analyses of problem behaviors were performed with three individuals with severe intellectual disabilities. Results indicated that the problem behaviors were maintained either when the behavior resulted in escape from difficult tasks or when the behavior resulted in access to preferred items. Training in functionally equivalent…
