Vocal stereotypy is a commonly occurring challenging behavior in children with autism spectrum disorder (ASD) that is frequently maintained by automatic reinforcement and often interferes with skill acquisition. Matched stimulation (MS), and response interruption and redirection (RIRD) are two interventions that have been demonstrated to be…

This study investigated performance under and preference for continuous and discontinuous work-reinforcer schedules in 3 students who had been diagnosed with autism. Under continuous schedules, participants completed all work and consumed all reinforcers in contiguous units. Under discontinuous schedules, work and reinforcer access were broken up…

Substantial experimental evidence indicates that behavior reinforced on a denser schedule is more resistant to disruption than is behavior reinforced on a thinner schedule. The present experiment studied resistance to disruption in a natural educational environment. Responding during familiar activities was reinforced on a multiple…

The present study compares the effects of providing choice between activities or between materials for completion of activities on the on-task behavior of 4 boys with autism spectrum disorders. Results showed that the participants displayed higher levels of on-task behavior during the choice conditions than in the no-choice condition. However, the…

We assessed the use of a joint activity schedule to increase peer engagement for preschoolers with autism. We taught 3 dyads of preschoolers with autism to follow joint activity schedules that cued both members of the pair to play a sequence of interactive games together. Results indicated that joint activity schedules increased peer engagement…

Differential reinforcement of alternative behavior (DRA) is used frequently as a treatment for problem behavior. Previous studies on treatment integrity failures during DRA suggest that the intervention is robust, but research has not yet investigated the effects of different types of integrity failures. We examined the effects of two types of…

Cooperative learning groups were used to integrate two students with autism into a fourth-grade social studies class. Academic performance, academic engagement, peer interactions, and social and behavioral skills were assessed. Benefits were noted both for the target students and their peers for academic outcomes and social interactions. (SW)

Functional communication training, extinction, and response chaining decreased escape-maintained aberrant behavior and increased task participation of 3 youth, ages 10 through 15, with moderate mental retardation, 2 of whom also had autism. Task escape was contingent on verbally responding and completing task steps. Behavior chaining also…

Prompting, positive and negative reinforcement, and a gradually extended reinforcement schedule were used with three autistic clients (two six-year-olds and one adolescent) to teach them to maintain on-task behaviors without constant supervision. Results indicated that appropriate behavior could be successfully maintained with only infrequent and…

A graduated guidance procedure was used to teach 4 boys (ages 9-14) with autism to follow photographic activity schedules to increase on-task and on-schedule behavior. Use of the schedules produced sustained engagement which generalized to a new schedule with a new sequence of photographs. Subjects were able to independently change activities in…
