This study examined a behavioral intervention package to promote the use of target vocalizations alongside speech-generating device (SGD) mands. Six minimally verbal children with autism spectrum disorder participated, including three with no prior SGD experience. During baseline, SGD responses resulted in access to a preferred item and there was…

Five participants with autism spectrum disorder (ASD) between the ages of 10 and 14 years attended a twice-weekly social skills group for 8 weeks. A multiple probe design across skills with concurrent replication across participants was utilized to assess the effects of social skills training using multiple exemplars and lag schedules on social…

Background: Needle phobias are common in children and adults worldwide. One effective intervention for this phobia is exposure therapy where a participant is gradually exposed to increasing levels of the fear-evoking stimulus while differential reinforcement is applied. This intervention, however, may be difficult to implement with some medical…

Noncontingent reinforcement (NCR) is an effective technique for reducing a variety of behaviors in individuals with autism spectrum disorders (ASD); however, prior researchers have not investigated the effects of NCR to reduce perseverative speech in children with ASD in naturalistic educational contexts. The current investigation evaluated the…

Research has shown that variability may be an operant dimension of behavior. One method of reinforcing response variability is to use a lag schedule of reinforcement (Page & Neuringer, 1985). Several studies have shown that a Lag 1 schedule is effective in increasing variable responding with human participants (e.g., Esch, Esch, & Love, 2009; Lee,…

Background: Positive behaviour support emphasises the impact of contextual variables to enhance participation, choice, and quality of life. This study evaluates a sequence for implementing changes to key contextual variables for 4 individuals. Interventions were maintained and data collection continued over a 3-year period. Method: Functional…

We manipulated relative reinforcement for problem behavior and appropriate behavior using differential reinforcement of alternative behavior (DRA) without an extinction component. Seven children with developmental disabilities participated. We manipulated duration (Experiment 1), quality (Experiment 2), delay (Experiment 3), or a combination of…

Recent mandates related to the implementation of evidence-based practices for individuals with autism spectrum disorder (ASD) require that autism professionals both understand and are able to implement practices based on the science of applied behavior analysis (ABA). The use of the term "applied behavior analysis" and its related concepts…

Stimulus fading in the form of gradually increased exposure to a fear-evoking stimulus, often combined with differential reinforcement, has been used to treat phobias in children who are otherwise normal and in children with autism. In this investigation, we applied stimulus fading plus differential reinforcement with an adolescent with autism and…

Play is, by definition, internally motivated, flexible, spontaneous and voluntary. Yet some researchers claim to have taught children with autism to play using behavioural interventions that are heavily structured, repetitive and make use of external reinforcements. In the current systematic review, we examine the extent to which these claims are…

Effects of a differential reinforcement of other behavior procedures (DRO) on the stereotypic responses and task performance of three autistic youth during dyadic instruction were examined. The procedures effectively reduced the stereotypic behavior of two children and substantially increased the task performance of the two lowest performance…

The effects of a procedure based on differential reinforcement of other behaviors (DRO) on stereotypic responses and task performance were tested with three autistic students (14-21 years old). The procedure was unique because the time interval employed between potential opportunities for reinforcement was the natural length of one instructional…

Results of the study involving three autistic Ss (four to six-years-old) showed rapid acquisition of target behaviors only when the target behavior was a direct part of the chain leading to the reinforcer. (Author)

Investigated whether (1) a highly discriminable treatment procedure in one setting would produce a behavioral contrast effect in unmanipulated settings, and whether (2) such contrast-like trends could be eliminated if initially different reinforcement procedures in two settings were subsequently made similar. (Author/DB)

Nonaversive procedures (including differential reinforcement of other behaviors, differential reinforcement of low rates of responding, differential reinforcement of alternative behavior, and stimulus control) were effective in bringing target behaviors under control for five students (14-17 years old) with autism or autistic-like behavior.
