Communication aid provision and use among children and adolescents developing aided communication: an international survey.

A fundamental requirement of a supportive language development for young children who need aided communication is that an aided communication system is made available and its use is supported. There is limited information about the age at which children are typically provided with a communication aid or about how aided communication is used in everyday situations. Using questionnaire-based interview data, this study investigated (a) the pattern of provision of communication aids to 84 children and adolescents, (b) parents' and professionals' evaluation of the quality of communication across contexts, and (c) availability and use of aided communication in these contexts.

Visual-spatial cognition in children using aided communication.

Children with severe motor impairments are restricted in their manipulation and exploration of objects, but little is known about how such limitations influence cognitive development. This study investigated visual-constructional abilities in 75 children and adolescents, aged 5;0-15;11 (years;months), with severe speech impairments and no intellectual disabilities (aided group) and in 56 children and adolescents with typical development (reference group). Verbal comprehension, non-verbal reasoning, and visual-spatial perception were assessed with standardized tests.

Vocabulary comprehension and strategies in name construction among children using aided communication.

Vocabulary learning reflects the language experiences of the child, both in typical and atypical development, although the vocabulary development of children who use aided communication may differ from children who use natural speech. This study compared the performance of children using aided communication with that of peers using natural speech on two measures of vocabulary knowledge: comprehension of graphic symbols and labeling of common objects. There were 92 participants not considered intellectually disabled in the aided group.
