As individuals with autism age out of the educational system, families and practitioners are faced with a number of challenges, including placement concerns and limited behavioral support. Among the most significant concerns is the assessment and treatment of challenging behavior in this population. While assessment and treatment strategies have…

Reinforcers contingent on response variability exert powerful and precise control over levels of variability, from stereotypy to stochasticity. This paper reviews how variability-contingent reinforcers interact with non-contingent, eliciting events to influence the variability of operant responses. Relationships to stimulus control, choice,…

This study evaluated the effects of using differential reinforcement of other behavior (DRO) with a differential reinforcement of alternative behavior (DRA) resetting time schedule to reduce stereotypy in a child with Rett Syndrome. The primary purpose of the investigation was to compare latency and choice as dependent measures to identify…

There are a number of instructional approaches available within ABA, each of which is uniquely suited to address specific deficits in learners with Autism Spectrum Disorders. Clinicians can utilize a combination of Discrete Trial Instruction (DTT), naturalistic strategies, and rate-building procedures to maximize the acquisition, generalization,…

We evaluated contingent and noncontingent practice of an alternative behavior (appropriate play) as intervention for stereotypy that occurred with two play objects in a 5-year old boy with autism. Contingent practice was implemented as a consequence for stereotypy, and the rate of noncontingent practice was matched (yoked) to that schedule. On…

The current study examined instructors' discrete-trial teaching responses after a performance-based training procedure in which instructors were required to demonstrate criterion-level performance on written and oral quizzes and on performance demonstrations. Twelve discrete-trial teaching responses were labeled and operationally defined.…

The present study suggests that initial learning rates of young children with autism receiving early, intensive, home-based behavioral intervention are moderately correlated with outcome variables after four years of treatment. 20 children with autism who had Childhood Autism Rating Scale scores between 37.5 and 58 and Vineland Adaptive Behavior…
