An ABAB reversal design was employed to evaluate the effect of differential reinforcement of low (DRL) frequency behavior as an interdependent group contingency on the frequency of vocal disruptions of five males, 6-14-years old, diagnosed with an autism spectrum disorder. The results showed lower frequencies of vocal disruptions during…

The necessity of promoting physical activity in individuals with Autism Spectrum Disorder (ASD) has been emphasized for decades. One of the barriers to participate in physical activity for individuals with ASD is limited interest and motivation. Therefore, understanding the motivation to exercise in this population is important. The objective was…

Introduction: Little is known about the effects of specific behavioral strategies to reduce stereotypy and self-injury for learners with sensory impairments and additional disabilities. Method: A single-subject, multi-treatment withdrawal design was used to test the isolated and combined effects of physical prompting to engage in object…

Children with autism spectrum disorder (ASD) often display impairments in communication, such as limited echoic behavior, few vocal-verbal responses, and a lack of functional communication. One potential way to foster the acquisition of vocal responses in individuals with disabilities is by conditioning vocalizations as reinforcers. Conditioning…

Functional communication training, an intervention for challenging behavior rooted in principles of applied behavior analysis, has copious empirical support dating back to the mid-1980s for autistic individuals. Recently, there has been a concerted effort to thin reinforcement delivery during functional communication training using…

Self-management has been found to be favorable for improving a wide variety of skills as well as decreasing problematic behaviors in individuals with a range of disabilities. We used a single case withdrawal design to investigate the use of a self-management intervention on problem behaviors of a nine-year-old Native American child with fetal…

Past research has demonstrated that pictorial preference assessments can predict subsequent reinforcement effects for individuals with developmental disabilities only when access to the selected stimulus is provided contingent on a pictorial selection. The purpose of the present investigation was to assess more comprehensively the feasibility of…

The graduated reinforcement procedure (also known as differential reinforcement) is an often-used procedure in the field of Applied Behavior Analysis to teach new skills and increase pro-social behaviors. In this study, the researchers used a multi-element design to evaluated the graduated reinforcement procedure for six children with a diagnosis…

Research has identified a variety of effective approaches for responding to errors during discrete-trial training. In one commonly used method, the therapist delivers a prompt contingent on the occurrence of an incorrect response and then re-presents the trial so that the learner has an opportunity to perform the correct response independently.…

Research on stimulus-stimulus pairing to induce novel vocalizations in nonverbal children has typically employed response-independent pairing (RIP) procedures to condition speech sounds as reinforcers. The purpose of the present study was to evaluate the effects of a response-contingent pairing (RCP) procedure on the vocalizations of three…

Research suggests that many children with ASD are visual learners (Quill, 1997) and may struggle to comprehend expectations presented in a verbal mode only. Visually structured interventions present choices, expectations, tasks, and communication exchanges in a way that is appealing and approachable for visual learners. There are many types of…

We compared the effects of Lag 0 and Lag 1 schedules of reinforcement on children's responses naming category items in a group context and subsequent responses emitted during individual testing in which the schedule of reinforcement remained Lag 0. Specifically, we measured response variability and novel responses to categories for 3 children who…

Several studies have suggested that contingent adult imitation increase nonverbal communication, such as attention and proximity to adults, in children with autism spectrum disorders. However, few studies have shown the effect of contingent imitation on verbal communication. This study examined whether children with autism were able to promote…

Although massed-trial instruction, distributed-trial instruction, and task interspersal have been shown to be effective methods of teaching skills to children with autism spectrum disorders, they have not been directly compared. In the current study, we taught 6 children to tact shapes of countries using these methods to determine which would…

Many children with autism spectrum disorder (ASD) require instructional programs that simultaneously address academic content, interfering behavior, and potential gaps in prerequisite skills for a given curriculum. This study examined the impact of an intervention package consisting of contingent reinforcement and match-to-sample training on the…
