Young children who cannot use their natural speech to communicate their daily wants, needs, thoughts, and opinions often rely on augmentative and alternative communication (AAC) strategies that frequently use graphic symbols to assemble messages. Early intervention strategies typically focus on visual scene displays (VSDs) to place target messages…

Treatment intensity is an aspect of communication intervention that has received limited empirical attention. In this article, we discuss key parameters of treatment intensity related to individuals with complex communication needs who use augmentative and alternative communication. We advocate for an examination of treatment intensity along with…

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 dissertation investigates ways of training adults to teach students with communication impairments to use augmentative and alternative communication (AAC) systems across a variety of environments. In addition to three stand-alone papers, it will start with an introduction and conclude with a discussion. Chapter 1 will provide the reader with…

Students with significant disabilities often struggle to communicate their wants and needs but can be taught widely recognizable communication with the aid of augmentative and alternative communication (AAC) supports. Simple speech generating devices (SGDs) such as Step-by-Step switches or GoTalk can be used by students to send specific messages.…

Students with autism spectrum disorder (ASD) have difficulties in communication that limit their opportunities to participate in daily living and educational activities. Augmentative alternative communication is one of the strategies used to strengthen the communication skills of students with limited communication skills. Students with ASD…

Students with visual impairment (VI) were taught to request using the Picture Exchange Communication System (PECS) and tangible symbols. Participants were four males with additional disabilities, 5 to 11 years old, who had little to no functional vision. A functional relation between PECS Phase 1 and requesting was established using a multiple…

This study evaluated the effects of a peer-delivered least prompts intervention and adapted read-alouds of a grade-level novel on correct listening comprehension responses for participants with moderate intellectual disability. Before the study began, participants were taught concepts for wh- words (i.e., who, what, why, when, and where), to…

This study investigated the results of employing shared story reading during literacy instruction for participants with severe and multiple disabilities. This intervention was conducted in an effort to improve independent responses made by participants with severe and multiple disabilities within a small group on a task analysis during shared…

Generalization is the key to effective autism intervention--when children can apply new skills across settings, they'll make broad, long-term improvements in behavior and social communication. The first how-to guide to generalization is finally here! Practical and reader-friendly, this is the book that helps professionals take today's most popular…

This paper provides results of a descriptive analysis of peer-reviewed, single subject design, intervention research on augmentative and alternative communication (AAC) for individuals with severe disabilities, from birth to 21 years, published in English between 1997 and 2003. A database of 40 studies was found that met seven specified criteria.…
