This study investigated the effects of a multiphase teacher professional development package on student use of speech-generating augmentative and alternative communication devices (SGDs). Teachers were taught (a) device operation and programming, (b) device integration and embedding using environmental arrangement strategies, and (c) systematic…

The aim of this study is to examine whether the asymmetrical pattern of communication usually found between people who use augmentative and alternative communication and their partners using natural speech was also found in the interaction between non-vocal young preschool children with cerebral palsy and their parents. Three parent-child dyads…

Evidence-based practice (EBP) is increasingly being advocated as the preferred approach to practice in augmentative and alternative communication (AAC). The EBP process involves multiple steps. The asking of a well-built question is the first step in the quest for answers. At the same time it is also often the first stumbling block for…

Augmentative and alternative communication (AAC) holds the potential to enable people with severe oral communication impairments to participate more fully in society. However, despite the development of increasingly sophisticated communication aids, as well as recent UK policy initiatives aimed at improving access to them, some major obstacles…

In a previous study, the authors identified final plosive voicing contrast as the highest single error source in dysarthria associated with Friedreich's Ataxia in a group of Irish English-speaking participants. This study aimed to determine the acoustic features underlying misperceptions of voicing status and implications for clinical management.…

Four commentaries on Levine et al. (EC 609 255) include "Negotiating the Facilitated Communication Maze" (Dianne Ferguson and Robert Horner); "Defining Facilitated Communication in and out of Existence: Role of Science in the Facilitated Communication Controversy" (David Goode); "A Dispassionate (If That's Possible)…

This response by the original authors (EC 609 255) to four commentaries (EC 609 256) notes the agreement of all that "authorship" is a major issue in facilitated communication and restates their contention that use of facilitated communication can cause considerable harm. They urge the use of augmentative communication techniques for…

This article introduces two major articles and four commentaries on facilitated communication with people having severe disabilities. Ten basic facilitated communication questions which these papers address are listed. (DB)

This response to Green and Shane (EC 609 759) and Biklen and Duchan (EC 609 760), which presented opposing views of facilitated communication (FC) with people having severe disabilities, focuses on alternative meanings of the controversy itself. It concludes that the controversy shows the need to resolve the conflict between systematic inquiry and…

This study reports descriptive findings regarding the scaffolding strategies used by an experienced practitioner during a shared book reading session with a student who uses augmentative and alternative communication (AAC). Specific scaffolding strategies are described and, in addition, the level of semantic complexity targeted by the practitioner…

This paper examines the role of augmentative and alternative communication (AAC) in fostering the successful inclusion of students with the most severe disabilities in general education. Best practices in AAC are identified and multiple examples of their implementation are presented. Particular emphasis is placed on the need to integrate AAC into…

Augmentative and alternative communication is a compilation of methods and technology designed to supplement spoken communication for people with limited speech or language skills, including children with developmental and intellectual disabilities. The field of AAC has evolved rapidly within the last 10 years, due to a combination of empirical…

Evidence-based practices (EBPs) are the basis on which teachers and other service providers are required to design educational programs for learners with autism spectrum disorders (ASD). As part of their work with the National Professional Development Center (NPDC) on ASD, researchers developed a process for reviewing the research literature and…

This paper addresses questions raised about the validity of facilitated communication with autistic individuals and others having severe disabilities and offers examples from the authors' program to support the validity of facilitated communication. Published studies showing a high rate of unfounded claims of abuse under facilitated communication…

This study, with 96 sales clerks, examined conversational trade-offs with customers using augmentative or alternative communication (AAC) in scripted videotaped conversational conditions. The clerks rated the conditions involving slowly delivered relevant messages higher than quickly delivered partly relevant messages. Also, messages preceded by a…
