Differential reinforcement of low rates of responding was used to reduce the disruptive behaviors of a blind 12-year-old boy with a learning disability. The subject earned reinforcers by not exceeding the established criterion of disruptive behaviors. An overall 88 percent reduction in target behaviors was observed across a 26-day period.…

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)

Investigation of episodes of injury and personal characteristics among 412 individuals with mental retardation living in Intermediate Care Facilities found that 16% of the group experienced 67% of injuries. Individuals taking antipsychotics, having higher maladaptive behavior scores, and having relatively higher levels of adaptive behavior were…

The appropriateness of the Aberrant Behavior Checklist (ABC) was investigated with 199 youngsters with dual diagnosis of mental retardation and psychiatric disturbance. With some cautions, the ABC is recommended, based on the robustness of its factor structure, clinically meaningfulness of the subscale scores, and internal consistency of the…

A functional analysis of eye poking by a four-year-old female with severe developmental disabilities and visual impairments showed that high rates occurred in all conditions. Attempts to identify the maintaining variable found that eye poking decreased only when finger-eye contact was interrupted by blocking the response. (Author/DB)

This study investigated diagnosis of learning problems in 177 boys (ages 6-13) with behavior problems. The standard score discrepancy method and standard score plus low achievement method were more likely to identify children with above-average intelligence quotients as learning disabled, whereas a regression approach identified learning…

This study with 65 individuals with mental retardation and additional seizure and/or psychiatric or behavioral disorders found that 9.2 percent experienced medication (carbamazepine) side effects, ranging from irritability to mania. More side effects were experienced by individuals with behavioral or psychiatric disorders than by those with an…

An ecological study was made of persistent repetitious movements by 12 developmentally disabled adults in a horticultural day work program. Fewer dysfunctional patterns occurred during times when staff were actively teaching than when the trainee was isolated or resting. Results argued for teaching skills in terms of coordinated response…

Fifty children and adolescents with affective disorders and mental retardation admitted to a psychiatric inpatient unit were compared with 50 inpatients without depression. Behavioral symptoms occurred significantly more often in the affective group than in the comparison group. The behavioral presentation of affective symptoms in children and…

Three individuals with multiple severe disabilities were taught an appropriate response to problem behaviors, but the response was less efficient than the problem behavior on physical effort, schedule of reinforcement, or stimulus-reinforcer time delay. The response did not compete successfully with the problem behaviors until a new, more…
