Angelman syndrome is a neurogenetic disorder characterized by intellectual and developmental disability. Common behavioral characteristics of this disorder include a heightened interest in social interactions and frequent bids to initiate interaction. These bids can be problematic, for instance, when a child attempts to hug strangers in public…

We analyzed the inappropriate social interactions of 3 students with Asperger's syndrome whose behavior was maintained by social positive reinforcement. We tested whether inappropriate social behavior was sensitive to social positive reinforcement contingencies and whether such contingencies could be reversed to increase the probability of…

Tier 2 interventions are implemented similarly across students and thus serve as an efficient and cost-effective method of behavior support in school settings. Check-in/check-out is a Tier 2 intervention with documented effectiveness (e.g., Hawken & Horner, 2003; Todd, Campbell, Meyer, & Horner, 2008). Key features of the intervention…

Social skills deficits are a defining feature of individuals diagnosed with autism and other pervasive developmental disorders (PDD), which can impair functioning and put the individual at higher risk for developing problem behavior (e.g., self-injury, aggression). In the current study, an adolescent with PDD displayed inappropriate social…

A study used functional analyses to identify the social variables that maintained the inappropriate social-communicative behaviors of two adolescent students with mental retardation. Results were used to identify appropriate, functionally equivalent behaviors that the students were taught to self-monitor. The use of appropriate social skills was…

Discusses behavioral momentum and the general behavioral relation between the persistence of behavior and the rate of reinforcement obtained in a given situation. Strategies for establishing the generality of behavioral relations are reviewed, followed by a brief summary of evidence for the generality of behavioral momentum. (Author/CR)

Reviews laboratory research on behavioral momentum conducted with pigeons and summarizes its findings and their generality to people, including those with mental retardation. Discusses the high-probability procedure used to establish compliance in clinical settings and based in part on an extension of the momentum metaphor. (CR)

This commentary discusses John Nevin's article on establishing compliance via behavioral momentum involving high-probability procedures, and questions whether applications of behavioral momentum can be derived from the theory, whether applications could have been developed if the theory not been formulated, and whether the theory will add…

A six-year old with developmental delays who exhibited aggression when asked to pick up his toys was studied to determine the effects of interventions. Treatment included praise, a break, and access to the toys contingent on compliance. Results showed aggression decreased only with social interaction during the break. (Author/CR)

Three mentally retarded students (ages 9-12) who exhibited challenging behaviors to escape from academic demands and to receive social attention were taught alternative assistance-seeking and attention-getting phrases. Data indicated that the intervention reduced challenging behavior. The results transferred across settings, and were maintained 18…

The effects on compliance of two types of differential negative reinforcement (DNR) were studied with a five-year-old girl with moderate mental retardation and a history of severe disruption. Escape from instructional trials was either contingent on a communicative behavior or compliance. Behaviors improved with both interventions, but compliance…

Two studies examined effects of combinations of setting events on social interactions of seven preschool children with language delays and social interaction deficits. The optimal combination of events for promoting peer interaction included teacher absence from the activity, a limited number and form of materials, and children paired with a…

Peers of a socially rejected seventh-grade girl were rewarded for publicly reporting positive aspects of the girl's behavior. Results indicated that positive peer reports reduced negative social interactions to near zero and increased positive interactions to above 70%. In addition, social acceptance ratings of the girl increased from…
