The study assessed the effects of a negative practice contingency plus DRO on the self-stimulatory hand-clapping of three developmentally disabled students, aged 6-9. The procedure was effective in suppressing the behavior, and follow-up observations showed that the occurrence of hand-clapping continued to be low. (Author/JDD)

A study of a man (age 19) with severe developmental disabilities evaluated the effects of implementing extinction for some problem behaviors of a functional response class, with and without reinforcement of an alternative communication response. Results found that using extinction and functional communication training reduced all topographies of…

A fading procedure was successfully used to maintain high levels of compliance obtained with presenting high-probability requests immediately antecedent to low-probability requests in both a 5-year-old boy with developmental disabilities and a 15-year-old girl with developmental disabilities (for whom rephrasing of "don't" requests to…

A study evaluated teaching a technique for self-control to three adults with developmental disabilities. Concurrent fixed-duration/progressive-duration reinforcement schedules were introduced in which both smaller and larger reinforcers were available immediately. When progressively increasing delays were introduced for the larger reinforcer,…

Exposure to alcohol in utero is considered to be the leading cause of developmental disabilities of known etiology. The most severe consequence of such exposure, fetal alcohol syndrome (FAS), is characterized by a distinct constellation of characteristic facial anomalies, growth retardation, and central nervous system (CNS) dysfunction. Some…

This paper explores the reasonableness of expecting conventional experimental methodologies and research reports on behavioral interventions for persons with developmental disabilities to both support the validity of promising practices and guide the efforts of practitioners to implement those practices. New directions for research and practice…

This article discusses the successes of behavior analysts in affecting challenging behaviors in persons with developmental disabilities. Three future issues are then addressed: the development of challenging behaviors, the role of rule-governance in challenging behavior, and the behavior of persons who directly apply functional assessment and…

A meta-analysis of the group intervention research for parents of children with developmental disabilities was conducted in order to characterize the efficacy of treatments in reducing depressive symptoms and other forms of psychological distress associated with stress in parents of children with developmental disabilities. An extensive search led…

The principle of motivation has resurfaced as an independent variable in the field of behavior analysis over the past 20 years. The increased interest is the result of the refinements of the concept of the motivating operation and its application to the learning needs of persons with developmental disabilities. Notwithstanding the increased…

Results of a series of three experiments with four developmentally disabled males (ages 7-13) who exhibited hand flapping and body rocking indicated that some forms of repetitive stereotyped behaviors may serve social functions (e.g., escape from aversive situations), and that teaching a functionally equivalent communicative alternative can be an…

Although the past decade produced great strides in rights protection for developmentally disabled youngsters, they may not be sufficient to the adequate safeguarding of children's rights. This article examines several program components that help to ensure children's rights through effective teaching and treatment methods, emphasizing training and…

Self-injurious behavior is a serious concern for individuals who must provide educational services to developmentally disabled children. This article discusses research related to the motivation of self-injury; provides guidelines for designing treatment programs for self-injurious behavior; and introduces a new nonaversive treatment, differential…

Discusses the effects of a cognitive-behavioral intervention that focused on facilitating expressive behaviors with their parents of 44 children (ages 22-32 months) with pervasive developmental delays and autism. Results found the program "Learning to Speak" increased the children's verbal compliance and decreased acts of verbal noncompliance. (CR)

An adolescent with developmental disabilities who used a wheelchair was anecdotally observed to display little aggressive behavior when being pushed, but higher rates when movement was terminated. A functional analysis confirmed the elevated aggression and the child was taught to request movement through appropriate means. Aggression decreased…

Surveys current research on causes and treatment of autism. Identifies features of autism and outlines causal theories and related treatments. Analyzes problems with the different approaches to causes of autism. Suggests the multiplicity of approaches implies lack of success in any one area. Contends behavior modification provides best results and…
