An experimental, single-subject research study investigated the comparative efficacy of the Picture Exchange Communication System (PECS) versus a speech-generating device (SGD) in developing requesting skills for three elementary-age children with severe autism and little to no functional speech. Results demonstrated increases in requesting…

A multiple probe across participants design was used to assess the effects of an intervention package on reading fluency and section-based and topography-based comprehension tasks. Participants were three adolescents diagnosed with high functioning pervasive developmental disorders. The intervention package consisted of listen passage preview,…

We compared two prompting techniques that are commonly used to teach individuals with autism. In the "most-to-least" (MTL) prompting condition, the therapist initially delivered the most intrusive prompt necessary to achieve a correct response. Prompts were gradually faded across subsequent trials, while errors resulted in the provision of…

The Barnet Early Autism Model (BEAM) for children with Autism Spectrum Disorder (ASD) was compared to a time-comparable approach (Portage) in terms of child outcomes and parental functioning. BEAM produced improvements in the adaptive behavioural function and language abilities of the children with ASD. Additionally, the programme produced…

Treatment implementation is an under-studied and under-reported aspect of intervention studies involving individuals with autism spectrum disorder (ASD). One primary area of concern is the lack of reliable and valid implementation measures, which allows a conclusive association to be drawn between the intervention and participant outcomes. This…

We evaluated a program for teaching two adolescents with autism spectrum disorders (ASD) to perform more advanced operations on an iPod-based speech-generating device (SGD). The effects of the teaching program were evaluated in a multiprobe multiple baseline across participants design that included two intervention phases. The first intervention…

School recess is an opportunity to include students with autism spectrum disorders (ASD) with their typically developing peers and is a setting in which instruction can occur. However, the educational opportunities for children with ASD within recess are often overlooked and recess time is being reduced or eliminated in the United States. This…

The purpose of the present investigation was to refine and validate an assessment procedure to identify instructional variables influencing acquisition of conditional discriminations in children diagnosed with autism. An assessment was implemented with eleven individuals to identify the specific instructional variables influencing the individual's…

We reviewed communication intervention studies involving people with Rett syndrome. Systematic searches of five electronic databases, selected journals, and reference lists identified nine studies meeting the inclusion criteria. These studies were evaluated in terms of: (a) participant characteristics, (b) target skills, (c) procedures, (d) main…

Computer-assisted instruction (CAI) is used to teach a variety of skills to children with developmental disabilities. However, it remains unclear whether CAI or direct instruction from a therapist produces better learning outcomes. In addition, no studies have evaluated the ease of training therapists to implement CAI versus direct instruction. In…

Classroom rules are an integral part of classroom management. Children with Asperger's may require systematic instruction to learn classroom rules, but may be placed in classrooms in which the rules are not explicitly taught. A multiple baseline design across students with probes for maintenance after the intervention ceased was used to evaluate…

Children with autism spectrum disorder show deficits in social skills such as initiating conversation, responding in social situations, social problem-solving, and others. These deficits are targeted through the use of social skills interventions, some of which use a technology-based approach as a resource-efficient alternative to common forms of…

Research on variations of video-based intervention (VBI) suggests that they can be effective for teaching individuals with disabilities a range of socially significant behaviors. Among the relevant studies and reviews, particular emphasis has been given to applications of these procedures for participants diagnosed with autism. The term…

Incidental teaching is a technique that is used to increase the spontaneous use of language. This study evaluated effects of a brief staff training procedures on instructors' incidental teaching responses and on student initiations. In three experiments, instructors of children with autism participated in individual or group training sessions…
