The study investigated whether significant differences existed among normally developing 3-year-old children in transparency and in the learning of symbols from three different graphic symbol systems (Blissymbols, Picture Communication System, and Picsyms) frequently used with augmentative communication devices for communication disordered…

This bibliography covers alternative and augmentative communication and includes English-language citations for books, journal articles, and conference proceedings. The list contains over 400 citations, organized in alphabetical order by author, with references to publications dated from 1973 to 1986. Each bibliographic entry is coded for the…

The paper describes the development of a computerized symbol processing system which allows nonspeaking severely handicapped persons to create communication electronically. Two pilot studies investigated the use of Rebus and Bliss Symbols with either an Apple Graphics Tablet or the Power Pad, a peripheral which allowed users to activate the…

The comparative translucency within and across 5 aided augmentative and alternative symbol systems for symbols representing 3 parts of speech (nouns, verbs, and modifiers) was investigated with 50 college undergraduates. Results indicated that translucency varies among systems or sets and among parts of speech. (Author/DB)

The investigation examined the transparency and recall of symbols representing three parts of speech (nouns, verbs, and descriptors) from three different graphic symbol systems (Blissymbols, Picture Communication System, and Picsyms) among adults with intellectual handicaps. Results suggested that Blissymbols were the least transparent and hardest…

This manual is intended to accompany a videotape entitled "Tangible Symbol Systems." The manual summarizes techniques shown in the videotape, gives additional background and technical information, and supplies recordkeeping forms.

The paper describes the Makaton Vocabulary as an alternative communication mode for children and adults with communication and language difficulties. The language program comprises the following components: a core vocabulary based on concepts/items needed to express essential needs and experiences; the use of signs and/or symbols always associated…

Symbol shelves are tools for developing two-way communication with multihandicapped children who can anticipate events, but who do not respond to speech or sign language. The purpose of symbol shelves is to allow children to be expressive through symbols, to enable them to feel some sense of control, and to serve as a bridge to a more formal…

This article reviews research on the role of symbolic, referent, and instructional variables on the acquisition of augmentative and alternative communication (AAC) symbols by individuals with autism and severe speech and language impairments. Two vignettes illustrate findings of the review. (Contains references.) (Author/DB)

Three of four severely retarded adolescents and young adults learned to use computer-based lexigrams to request foods and, subsequently, objects. Additional request experience with lexigrams resulted in consistent improvement on labeling and comprehension tasks, emergence of subject-initiated lexigram communications, and facilitation of spoken…
