This study compared simultaneous prompting with an error correction procedure for teaching three children diagnosed with autism spectrum disorder expressive labels. Using a parallel treatment design nested within a multiple probe design, the researchers taught each participant how to expressively label pictures of sports teams or cartoon…

Working with a post-secondary student with intellectual disability, an adapted alternating treatments design was used to compare sight-word acquisition across three computer-delivered learning trial interventions: one with fixed 5-s response intervals, another with fixed 1-s response intervals, and a third with self-determined intervals. Visual…

A high-quality education in the social studies is recommended by the National Council for the Social Studies to promote civic competence and democratic participation for school system graduates. Currently, limited empirical information exists to inform social studies instruction for students with significant intellectual disability (SID),…

Purpose: Children with autism spectrum disorder (ASD) and complex communication needs are increasingly taught to use tablet-based speech-generating devices (SGDs). An important issue in designing such interventions is the selection of an appropriate format for displaying vocabulary. The purpose of this study was to determine (a) whether young…

This study examined the effects of an intervention that integrated peer-mediated instruction (PMI) with augmentative and alternative communication (AAC) using speech-generating devices (SGDs). Nine trained peer tutors without disabilities taught science concepts and modeled use of SGDs following a script to three elementary school students with…

This study evaluated the effects of progressive time delay (PTD) to teach four elementary students with intellectual disability on how to self-instruct using a video activity schedule. A single-case multiple probe across participants design with a multiple probe across environments design for each participant was used to assess the generalization…

Background: With rates of autism diagnosis continuing to rise, there is an urgent need for effective and efficient service delivery models. Pivotal Response Treatment (PRT) is considered an established treatment for autism spectrum disorder (ASD); however, there have been few well-controlled studies with adequate sample size. The aim of this study…

The purpose of this study was to examine the effectiveness of two error correction (EC) procedures: modeling alone and the use of an error statement plus modeling. Utilizing an alternating treatments design nested into a multiple baseline design across participants, we sought to evaluate and compare the effects of these two EC procedures used to…

Young adults with autism spectrum disorder (ASD) and comorbid intellectual disability (ID) are vastly underrepresented in the area of postsecondary employment. This study evaluated the effectiveness and perceptions of an intervention package incorporating constant time delay (CTD) and eCoaching to promote employment skill acquisition. CTD was used…

Individuals with low functioning autism spectrum disorders (LFASD) who demonstrate significant cognitive and communication needs benefit from using technology for learning graphic symbols for enhancing participation. This study investigated if an iPad application would increase identification of graphic symbols by children and adults with LFASD.…

This study describes the development and evaluation of a behavioral parent training protocol via telecommunication for three parents of preschool children with autism, with limited access to behavioral expertise. A single-subject, multiple baseline experimental design across child behaviors, replicated across parents, was used to evaluate the…

Self-instruction for individuals with an intellectual disability can be viewed as a pivotal skill in that once learned this skill has collateral effects on future behaviors in various environments. This study used a multiple probe across participants design to evaluate video modeling to teach high school students with an intellectual disability to…

We utilized a cool versus not cool procedure plus role-playing to teach social communication skills to three individuals diagnosed with autism spectrum disorder. The cool versus not cool procedure plus role-playing consisted of the researcher randomly demonstrating the behavior correctly (cool) two times and the behavior incorrectly (not cool) two…

The current study evaluated a relatively new video-based procedure, continuous video modeling (CVM), to teach multi-step cleaning tasks to high school students with moderate intellectual disability. CVM in contrast to video modeling and video prompting allows repetition of the video model (looping) as many times as needed while the user completes…

Omid early intervention resource kit containing information booklets on autism spectrum disorders (ASD) and related issues, five packs of tangible selected playthings and communication facilitating aids was developed and evaluated with 65 Iranian parents. Beside a pretest before the resource kit deliverance, parents in the control group took part…
