Ecobehavioural analysis procedures were used to examine the interactive engagement of children with developmental disabilities due to Down syndrome who attended inclusive preschools for 2 years. Compared with typical children, the children with disabilities displayed infrequent interactions with peers for the duration of the study. For the…

This position statement from the Critical Issues Committee of the Developmental Disabilities Division of the Council for Exceptional Children focuses on clarifying the place of autism spectrum disorders within the field of developmental disabilities. The representation of concerns relating to autism spectrum disorders by the Developmental…

Prevalence rates of epilepsy are much higher among persons with developmental disabilities compared to the general population. Anticonvulsant medication is the most common method of treating seizure disorders. Many of these antiepileptic medications (AEDs) are associated with various side effects, which may have detrimental effects on the social…

This study examined the persistence of early emerging aberrant behavior in 13 preschool children with developmental disabilities. The severity of aberrant behavior was assessed every 6 months over a 3-year period. Teachers completed the assessments using the Aberrant Behavior Checklist [Aman, M. G., & Singh, N. N. (1986). "Aberrant…

The Rhythmic Movement Test (RMT) evaluates temporal and amplitude parameterization and fluency of movement execution in a series of rhythmic arm movements under different sensory conditions. The RMT was used in combination with a jumping and a drawing task, to evaluate 36 children with Developmental Coordination Disorder (DCD) and a matched…

Background: A sample of community-based service users with intellectual disability (ID) was re-examined after 5 years to determine the impact of a diagnosis of personality disorder (PD). Methods: Seventy-five of the original 101 participants were followed up. Of these, 21 people had a PD identified during the original study. Results: Compared with…

The purpose of this project was to demonstrate untrained vocal requests in three adults with severe developmental disabilities. Specifically, we evaluated whether a history of reinforced relational responding would give rise to untrained vocal requests for novel items. Participants were first taught to request preferred items using their category…

The Norwegian Welfare System and how its programs support Norwegians with intellectual and developmental disabilities is described and proffered as a case example of how one nation's public policy shifted to provide community-invested services for people with lifelong disabilities. The foundation of Norway's shift to complete reliance on home and…

The present paper gives an overview of some of the modular day courses offered and, in some cases, developed by tutors at a former hospital school providing education to adults with severe learning disabilities. The aims of the courses were cognitive and personal development, as well as aesthetic and spiritual enrichment. Art history was offered…

In this article, the authors examine the contributions of a progressive form of postmodern social theory to raising substantive issues about the politics of knowledge or the factors that govern decision processes regarding the nature of evidence from research. They examine the basis for the reaction against postmodernism that has appeared in the…

Relationship quality (rapport) between people with developmental disabilities and their caregivers has long been suggested as an important variable influencing the likelihood of problem behavior. However, to date, the association between rapport and problem behavior has not been systematically investigated. The authors evaluated a multimethod…

In this article, the author talks about the concept underlying the term metal retardation and the effort to define it in a way that is scientifically accurate and in a way that promotes greater sensitivity to the needs of people described by the term which has been continuous for centuries. The author states that a scientifically sound and…

In this paper, I am going to examine the disorder of psychopathy and consider how genetic anomalies could give rise to the relatively specific neuro-cognitive impairments seen in individuals with this disorder. I will argue that genetic anomalies in psychopathy reduce the salience of punishment information (perhaps as a function of noradrenergic…

An objective method is presented to group discrete self-injurious behavior (SIB) events into bouts. Survival analysis was used to determine how long after an SIB the probability of observing a subsequent SIB remained elevated. This estimated bout length criterion time point was determined individually for 19 subjects with developmental disorders…

Functional analyses were conducted during a double-blind, placebo-controlled study of the atypical antipsychotic medication risperidone with 13 individuals. Risperidone was effective in reducing destructive behavior (compared to placebo) for 10 participants. For 7 of these responders, an undifferentiated pattern of responding occurred across their…
