The aim of this study was to examine how early symbolic forms (and their associated communicative functions) are related to change in communication among a sample of 12 young children with autism spectrum disorder (ASD) who produced two or fewer spoken words ("M" age = 28.75 months; 11 male, 1 female). Parents reported on children's…

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…

Use of logographic symbol systems with severely communication-disordered children led to a comparison of the relative ease of learning logographs from the Bliss and Rebus symbol systems with 32 normal preschoolers. Results indicated that Rebus symbols were recalled with significantly greater accuracy than Bliss symbols. (Author/DB)

The article reviews augmentative and alternative communication symbol classifications reported in the literature over the past decade. The "aided/unaided" dichotomy (based on user production of the symbol) is proposed as the superordinate level of classification, rather than the "static/dynamic" (based on transmission of…

The article addresses the need to identify the unconventional, nonsymbolic behaviors of children with severe, multiple disabilities. Suggestions for improving the frequency and quality of communicative interactions by building on the child's current behavioral repertoire. (Author/DB)

Literature is reviewed on augmentative and alternative communication research and intervention for individuals with severe intellectual disabilities. The review focuses on prerequisites for intervention, symbol systems and sets, computer technology, and teaching strategies. Future research directions are outlined, and clinical and educational…

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)

This study, involving 40 preschool children with normal cognitive abilities, determined the effects of initial teaching of semantic elements on compound Blissymbol acquisition, retention, and generalization in a story-telling context. Results indicated that the initial teaching of elements did not contribute to compound acquisition and retention…

A survey of 429 schools serving children classified as ESN(S)--educationally subnormal (severe)--or otherwise handicapped was conducted to find out which sign and symbol systems were used for nonvocal children. (SBH)

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)
