This study examined the effects of methylphenidate drug therapy and differential reinforcement on the disruptive behavior and task engagement of 3 children (ages 6 through 11) with mental retardation. Results indicated that both interventions were effective for two of the children. No evidence of an additive or synergistic effects of the two…

Basic and applied research on variables that influence the extinction of operant behaviors is reviewed and applied to the treatment of behavior disorders. The potential value of a general technology for the use of behavioral extinction is discussed. The paper concludes that current research findings are not sufficient for the development of 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…

Generalization across three stimulus parameters (therapist, setting, and demands) was examined for five men with severe/profound mental retardation whose self-injurious behavior was maintained by escape from task demands. Variables were held constant during the escape extinction treatment. Full or partial generalization to novel situations was…

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)

Discusses a study of the effects of a schoolwide behavior management program on Australian elementary school teachers' use of encouragement. Concludes that, although teacher encouragement of students increased during the program, encouragement levels reduced following the intervention's withdrawal. Calls for further research into the effects of…

High-probability requests were used to increase responsiveness to low-probability requests to initiate social interactions in three young boys with severe disabilities who were severely socially withdrawn. Increases were also found in unprompted social initiations and generalizations to a nontraining setting. Maintenance after training was also…

A multicomponent intervention to change problem behavior, which prevented community integration of three adolescents with autism, was evaluated. The intervention (implemented in a supermarket setting) included choice making, embedding, functional communication training, building tolerance for delay of reinforcement, and presenting discriminative…

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…

A stimulus preference assessment was evaluated with an adult and a child with profound mental retardation and severe self-injurious behavior, in order to better predict both the beneficial and negative side effects of stimuli in differential-reinforcement-of-other-behavior treatments. (DB)

This study of 15 children with feeding disorders investigated identification of effective behavioral reinforcers by comparing outcomes and time requirements of two procedures in which presence in a particular area produced access to a preferred stimulus (i.e., zone discrimination). Both procedures were viable reinforcer identification tools, but…

This study compared visual analyses with five alternative methods for assessing the magnitude of effect with single subject designs. Each method was successful in detecting intervention effect. When rank ordered, each method was consistent in identifying the participants with the largest effect. We recommend the use of the standard mean difference…

Deficiencies in social competence constitute a significant problem for aggressive children. As a result, these children often experience difficulty interacting with peers in socially acceptable ways. Such problems are particularly exacerbated in the schoolyard, where rules are less defined and low levels of supervision prevail. The present study…

This study describes responsibilities and training needs of paraeducators in physical education. Paraeducators (n = 138) employed in 34 midwestern schools received a 27-item questionnaire. Of the 138 paraeducators contacted, 76 responded, resulting in a 55.1% response rate. Only 16% of the total respondents (n = 76) reported receiving specific…

The social learning approach to marital and family therapy emphasizes the importance of clients' compliance with homework assignments to treatment progress. To investigate the relationship between clients' homework compliance and therapists' and clients' behaviors during therapy sessions and clients' intrasession tension and satisfaction, the…
