The study evaluated a reinforcement theory of stereotyped behavior with six autistic students (ages 9-16). Three students evidenced decreases in stereotypy and increases in responding in the presence of usual reinforcers, while the other three students required external suppression of stereotypy before increases in responding were shown.…

In response to a previous article proposing perceptual reinforcement of stereotyped movements in autistic and mentally retarded persons, it is argued that this theory fails to take into account biological findings and theory regarding pathological stereotyped acts. An alternative theory derived from neurological concepts is suggested. (Author/DB)

The study evaluated the effects of a time-efficient reinforcer assessment package with three preschoolers with autism. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, and yielded expected improvements in accuracy. (Author/DB)

The Milestone Reinforcer Survey was developed to assess reinforcer preferences of adults with mild to profound retardation living in community settings. Psychometric properties of the survey were established with 120 adults. The total reinforcer scores were found to be internally consistent, consistent across raters, and stable over time.…

This study examined methods for determining how extinction should be applied to different functions of self-injurious behavior, specifically head-banging of three children with developmental disabilities. Since each subject's head-banging was maintained by different reinforcement contingencies, behavioral treatment techniques, although all based…

This replication study found that only 16 of 55 raters agreed on the category of reinforcement maintaining a disabled individual's self-injurious behavior after using the Motivation Assessment Scale. Additionally, only 15 percent of the correlation coefficients obtained were above 80 percent, and none of the reliability scores was above 80…

A comprehensive evidence-based treatment for substance abuse and other associated problems (Family Behavior Therapy) is described, including its application to both adolescents and adults across a wide range of clinical contexts (i.e., criminal justice, child welfare). Relevant to practitioners and applied clinical researchers, topic areas include…

Analysis of videotapes of training procedures with 12 developmentally disabled adults in a horticultural day work program found an overall staff emphasis on selectively attending to workers' successful behavior with evidence of both efficiency and effectiveness of this approach. (Author/DB)

This article describes an intervention in which three parents were taught to use facilitative strategies when interacting with their children with profound mental retardation. The intervention consisted of reinforcing appropriate parent behavior as it was being observed by them on prerecorded videotapes. Facilitative strategies included the use of…

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…

A home-based reinforcement program was instituted with three underachieving fourth graders who exhibited inappropriate behavior. Each day the children brought home a workbook assignment indicating percentage of correct responses and parents provided reinforcement for correct items and for improvement over time. Effectiveness on completion of daily…

This final report analyzes results of a comprehensive, integrative review of 273 primary research studies on modifying attitudes toward disabled persons. Attitude modification approaches identified included providing information, direct contact with disabled persons, vicarious experiences related to having a disability, systematic desensitization,…

This paper describes the implementation and effects of a behavior management system in eight middle schools, including control schools, in an urban school district. The components of the system included school discipline policy review and revision, computerized behavior tracking, classroom organization and management, and positive reinforcement.…
