Examines the Child Language Data Exchange System (CHILDES), its organizational form, and its three major tools: (1) the CHILDES database of transcripts, (2) the CHAT system for transcribing and coding data, and (3) the CLAN programs for analyzing CHAT files. (GLR)

Jean Piaget's ideas regarding symbolic function are expanded in this paper to provide a model to use in distinguishing between general symbolic versus specific linguistic deficits in language disordered children (whose disorders are not due primarily to intellectual, sensory, motor, or social-emotional deficits). In applying this model to the…

Review of literature on indicators of the effectiveness of language intervention programs for autistic children showed that mitigation in echolalia was a critical characteristic, as it implied that the prerequisites for language were accessible through speech. Children whose speech ranged from mutism to unmitigated echolalia had a more negative…

Attempts to demonstrate that specifically language-impaired (SLI) children can be viewed as normal learners faced with systematically altered input. By assuming SLI children are limited in their ability to perceive and hypothesize grammatical morphemes that are low in phonetic substance, many features of SLI children's language can be explained by…

Idioglossia is a private communication system, most commonly occurring in twins. It also occurs between singletons and between other siblings of multiple births. These communication systems range from manual gestures to a fully developed vocal language with its own grammar. The literature of idioglossia is scanty and largely anecdotal. Much of the…

Discusses research results that demonstrate that nonlinguistic symbolic deficits of language-impaired children may actually reflect resource allocation constraints and cross-modality deficits. Discusses implications of studies that contrast symbolic action development in normally developing children with that in children with specific language…

Discusses the language development in individuals with Down's syndrome in both early childhood and adulthood, and outlines intervention programs to assist language development in these individuals not only in their early years but throughout their lives. (71 references) (CFM)

The views of proponents and opponents of the language deficit theory--the theory that nonstandard dialect is a deficient form of language--are presented in this paper. Following a description of the work of Basil Bernstein, a British educator who is considered the key figure among proponents of the theory, the paper presents an overview of the…
