Presents a culturally sensitive four-part augmentative and alternative communication assessment protocol. The protocol is inclusive, emphasizing the need to address cultural features directly, and it includes a self-assessment for all practitioners before they engage in the delivery of services to children from different cultural backgrounds.…

Investigated the effects of a peer network strategy on the duration of social interaction and social communication skills for three elementary students with autism. Results indicate increased social interaction time and use of an augmentative communication system for all three students, with increased expressive language for two students.…

Effects of synthetic speech output on the learning of graphic symbols by three adults with severe to profound mental retardation and communication impairments were evaluated. All participants achieved criterion learning using synthetic speech; two also reached criterion without synthetic speech, but the addition of synthetic speech resulted in…

An experiment was conducted to investigate the influence of three variables (type of augmentative technique used to communicate, disability label, and user competence in communicating with an augmentative technique) on the attitudes of 289 preservice speech pathologists. Findings indicate that user components influenced cognitive evaluations, but…

This review of the literature synthesizes theory and research on the use of speech output communication aids to determine potential benefits for persons with autism. Although results suggest such aids are likely to be useful with this population, the paper urges research into the characteristics of synthetic speech in conjunction with the learning…

Although the Minspeak[TM] approach is used on communication devices worldwide, little research has been conducted on its applicability within specific cultural contexts. The impact that users' familiarity of symbols and associations can have on learnability necessitates more systematic research. This study was an investigation into the…

I investigated the presence, utility, and emergence of tacit knowledge in 9 study participants who used assistive-augmentative technology. I conducted phenomenologic interviews, audio-taping, and transcribed the interview with the written consent of the participants. Sixteen highly trained experts critiqued the final product of the interviews and…

This study examined how children's attitudes toward a peer who used augmentative and alternative communication (AAC) were influenced by type of AAC device accessed by the child for communication. Specifically, the influence of dynamic screens vs. static screens was investigated. Two videotapes were created. In one a child used a dynamic screen…

Designed for teaching the related services staff, residential care providers, and families of individuals with severe hearing and vision impairments, this booklet explains the issues related to developing a communication system using textures. The texture symbols described are intended for use by individuals with dual sensory and multiple…

Describes recent advancements in augmentative and alternative communication aids for individuals with disabilities, explaining what speech recognition and speech output devices are, defining communication aids, examining features of communication aids, and describing various dedicated (strictly for communication) and nondedicated (computers with…

Thirty children (age 2) were assigned to three system approaches: vocabulary in a grid format organized taxonomically; vocabulary in a grid format organized schematically; and vocabulary in an integrated scene organized schematically. Children performed poorly in all conditions but were able to locate more items in the schematic scene condition.…

A 10-year old with severe intellectual disability, no spoken language, and poor language comprehension learned to use 9 object symbols when these were taught directly in a functional choice-making context. Difficulties with research methodology for this type of intervention are addressed. (Author/DB)

This article presents and explains the Preschool Checklist, a measure that incorporates research-based guidelines for developing preschool programs that include children with severe disabilities. The checklist assesses four areas: (1) scheduling and instructional arrangements; (2) socialization and communication; (3) alternative communication; and…

Six individuals (ages 10 to 44) with communication disorders who used augmentative and alternative communication were provided instruction on the acquisition, generalization, and long-term maintenance of partner-focused questions. Instruction used least-to-most prompting hierarchy in real-world interactions and simulations. All subjects learned…
