This study investigated whether a systematic instruction package was effective in child acquisition of question answering using an iPad-based speech generating device (SGD). The study was conducted with two children with autism using a multiple probe across behaviors design. Results demonstrated that the systematic instruction package consisting…

The Picture Exchange Communication System (PECS) is a popular augmentative and alternative communication intervention for individuals with developmental disabilities that includes six, sequential phases of instruction. We systematically reviewed published and unpublished single-case PECS studies for details about the percentage of participants…

Children with intellectual disabilities experience well-documented challenges in the development of problem-solving, particularly related to mathematical word-problem solving. Such challenges are related to both linguistic and conceptual skills. While interventions to assist children in developing conceptual skills are well reported, linguistic…

There is a lack of research on effective interventions to improve the early numeracy skills of children with severe disabilities---autism spectrum disorder, developmental disability, and intellectual disability---and complex communication needs. While preliminary research suggests the Early Numeracy curriculum is effective for teaching children…

Children with autism spectrum disorders (ASDs) often demonstrate delays in early language and literacy skills. Shared reading, the practice of adults reading aloud to children while using behaviors (e.g., asking questions) that are meant to promote interaction between the adult and child, is an intervention that has had positive effects on those…

Previous research on the use of voice output communication aids (VOCAs) has found a number of positive effects on the behavior of both the VOCA user and their communicative partners. Among these outcomes, studies have found that incorporating speech output into language learning tasks may result in faster and more efficient learning for adults…

Individuals with autism spectrum disorder (ASD) often have difficulty generalizing newly acquired communication skills to different contexts. In this study, a multiple baseline across settings (clinic, school, and home) design was used to determine whether an 8-year-old boy with ASD could learn to approach communication partners to request…

Non-verbal children with autism are candidates for augmentative and alternative communication (AAC). One type of AAC device is a voice output communication aid (VOCA). The primary drawbacks of past VOCAs were their expense and portability. Newer iPod-based VOCAs alleviate these concerns. This dissertation sought to extend the iPod-based VOCA…

Through contributions from top leaders in Autism Spectrum Disorder (ASD), "Children and Youth with Autism Spectrum Disorder" examines the ASD research literature, discusses procedural implications, and makes recommendations for future practice and inquiry. It combines the most recent developments in established practices with newer and…
