Language problems can be associated with specific genetic syndromes, such as Klinefelter syndrome and fragile X syndrome, even in the absence of intellectual and developmental disabilities. Turner syndrome, a relatively common genetic disorder, is caused by the complete or partial absence of 1 of the 2 X chromosomes typically present in women. The…

Velo-cardio-facial syndrome (VCFS) is a genetic disorder caused by a microdeletion of chromosome 22q11.2. Although there is some variability, VCFS is associated with a characteristic physical, behavioral, and cognitive phenotype. This review article focuses on aspects of language and literacy development in VCFS, describing what is known and…

Williams syndrome is a rare neurodevelopmental disorder caused by deletion of approximately 25 genes on chromosome 7q11.23. Children with the syndrome evidence large individual differences in both broad language and reading abilities. Nevertheless, as a group, children with this syndrome show a consistent pattern characterized by relative…

The validity of facilitated communication's effects are viewed from three perspectives, labeled as the plausible perspective, which is unexpected literacy; the skeptical perspective, which claims that social-communicative variables unintentionally influence intervention outcomes; and the enigmatic perspective, which neither rejects outright the…

Print materials, experiences, and writing technologies were introduced to three preschoolers (age 3) with autism and severe communication impairments. The goal was to increase natural literacy learning opportunities. Children found the materials and experiences interesting and their understanding and use of print materials and tools increased in…

The impact of a disordered phonological system (expressive or receptive) on language development is examined. Research results and guidelines are presented for identification of critical intelligibility and phonological awareness deficiencies and for intervention. Options for expediting intelligibility gains and research findings on enhancing…

This review examines the research on literacy expectations and priorities for students using augmentative and alternative communication systems as well as for students without disabilities. It discusses implications of research findings for education and clinical practice, such as integrating literacy instruction with other activities, fostering…

This article explores the effect of augmentative and alternative communication systems on literacy acquisition by young children with severe speech and physical impairments. The possibility of a relationship between the type of graphic symbols used for communication as a preschooler and the child's early reading competency is considered. (DB)

A theoretical framework for how literacy is learned and an overview of some special learning and technological needs of persons with severe speech and physical impairments are presented. Guidelines are offered for appropriate software selection and specialized computer adaptation for speech output and physical access. (DB)
