This study provides an analysis of case law concerning applied behavior analysis (ABA) for students with autism to determine outcome-related factors. The authors classified the 68 pertinent hearing/review officer and court decisions published in EHLR ("Education for Handicapped Law Report") and IDELR ("Individuals with Disabilities Education Law…

Background: Recent research has shown that the range of repetitive behaviour seen in individuals with Prader-Willi syndrome (PWS) extends beyond food-related behaviour. Methods: The presence and intensity of repetitive, rigid and routinized behaviour in children with PWS was compared with that seen in children with another neurodevelopmental…

Three-step prompting is a procedure commonly used in behavioral assessments and interventions; however, little research has evaluated the effects of this procedure on increasing children's compliance with caregiver requests. In this study, caregivers of children who demonstrated low levels of compliance were trained to use three-step prompting…

Describing the state of the science of ABA, this comprehensive handbook provides detailed information about theory, research, and intervention. The contributors are leading ABA authorities who present current best practices in behavioral assessment and demonstrate evidence-based strategies for supporting positive behaviors and reducing problem…

The paper traces the origins of the definitions of autism, notes controversies over its etiology, and discusses the wide variety of intervention approaches used. Psychoeducational approaches, such as play therapy and B. Bettelheim's psychoanalytic approach, are described and criticized in terms of premises and the anecdotal nature of evaluation…

The study compared the efficacy and setting generalization of sensory extinction and overcorrection in suppressing self-stimulation in two autistic children (ages 7- and 12-years-old). Results indicated that sensory extinction significantly decreased self stimulation in the structured setting but did not generalize to other settings.…

For a seven-year-old autistic boy, contingent jogging caused a significant decline in frequency of out-of-seat behavior that was maintained for 12 months. Unlike many other behavior suppression techniques, contingent exercise is safe and does not humiliate the client. (Author/LHW)

Consistent, unemotional use of timeout, without ancillary punishers, is shown to result in typical extinction curves (rather than the steeper gradient of punishment curves) for both autistic and mentally impaired children with widely different abrasive behaviors. Dangers of punishment and the therapeutic value of reduced environmental stimulation…

The author reviews recent literature dealing with teaching autistic children acceptable behaviors. Using E. Ornitz and E. Ritvo's description of autism, teaching procedures to overcome weaknesses in perceptual difficulties, bizarre movement, and problems in relating are discussed. (CL)

A functional assessment interview was conducted with care providers of 100 children (ages 2-5) with autism regarding reinforcement contingencies contributing to maintenance of disruptive behavior. Gaining access to perseverative activities and escaping demands while engaged in these activities frequently contributed to disruptive behavior in the…

A study examined the effectiveness of the Power Card Strategy in teaching sportsmanship skills to a 10-year-old girl with autism. The strategy incorporates special interests to teach and reinforce academic, behavior, and social skills. The strategy was effective in teaching sportsmanship skills and the behavioral generalized across multiple…

The study assessed whether 4 students (ages 9-13) with severe autistic disabilities could learn to use a self-management treatment package to reduce stereotypic behavior. Use of the procedures greatly reduced levels of stereotypic behavior. Improvement also occurred for extended periods of time in new settings without the presence of a treatment…

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)

This study, with a young autistic child and a young adult with profound mental retardation, demonstrated the effectiveness of a gradual, changing criterion process of stimulus shaping in training subjects to independently perform tasks with relatively high task requirements. (DB)

A script fading procedure was effectively used to teach 4 children (ages 9 and 12) with autism to initiate interactions with peers. Increased initiations (to within normal levels) generalized to a different setting, and for three of the children were maintained at two-month follow-up. (Author/DB)
