Individuals diagnosed with autism spectrum disorder (ASD) who engage in stereotypy may also emit a prior, temporally contiguous, high-risk response to access stereotypic behaviors. For example, the participant in this study who was diagnosed with ASD engaged in a chained response that included elopement, often in unsafe locations, to access light…

Evidence-based treatments for autism spectrum disorders (ASD) are comprised of components that identify therapist behavior necessary to implement the treatment with integrity. Some components are shared across approaches from diverse theoretical backgrounds. One component included in several interventions that has not been researched in isolation…

Stereotypic behavior exhibited by a third grade boy with autism was maintained by automatic reinforcement and occurrences of stereotypy were brought under stimulus control. The intervention consisted of pairing a green discriminative stimulus card (SD) with free access to stereotypy and a red card (SD absent) with vocal redirection and blocking…

Three punishment procedures--contingent applications of water mist, lemon juice, and vinegar--were evaluated as aversive treatment methods for a self-stimulatory behavior exhibited by a severely retarded 11-year-old male. The water mist procedure was as effective as lemon juice or vinegar, presented less physical threat to the client, and was…

Two short (20-second and 60-second) overcorrection procedures were effective in suppressing stereotypic behaviors of a 7- and a 12-year-old autistic student. (CL)

Analysis of effects of intertrial intervals on correct responding and self-stimulatory behavior by four autistic children (6-11 years old) revealed that short intertrial intervals produced decreased levels of self-stimulation and increased levels of correct responding. (Author/CL)

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…

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)

Three experiments were conducted with two participants with mental retardation that displayed property destruction and stereotypy. The experiments assessed the function of the responses, determined their relationship, and developed a treatment to reduce property destruction. Response blocking reduced property destruction (and attempts), prevented…

Twelve papers focus on issues involving severe behavior disorders in the schools and autism. The following papers are included: "Behavioral Ecology--A Unifying Strategy for the '80s" (F. Hewett); "Academic Skill Development--The Promise of Modeling Strategies" (R. Gable, J. Hendrickson); "Future Directions in Self-Control Research" (R. Rueda);…

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…
