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…

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)

Discusses the assessment of children's early language comprehension by the use of (1) parent reports; (2) preferential-looking models; and (3) event-related brain potentials. Examines recent findings on dissociations between language comprehension and production in normal, late-talking, and brain-injured children and considers the implications of…

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 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)

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…

Reviews the methodological issues raised by previous research into the language used by thought-disordered and nondisordered schizophrenics. (FL)

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…

Two approaches to intervention geared to autistic children's characteristics are presented: one stressing speech and the other sign and speech. Some findings relevant to implementation of simultaneous sign and speech are discussed, and due to observed variability in processing and responsiveness to intervention, the need for individual programing…

Children with language disorders experience problems in three dimensions of semantics: (1) content of content (reference, referents, concepts); (2) form of content (structural units of meaning); (3) use of content (functional variation in meaning). Teacher intervention strategies in each area (e.g., for problems of reference, sentence meaning,…

The authors address several issues pertinent to designing environmentally based total communication assessment and training programs for language delayed hearing children for whom oral language training alone is inadequate. (Author/CL)

Research on the environmental conditions promoting generative language learning is reviewed. Recombinative generalization is introduced as a principle of stimulus control that enables individuals to express and to comprehend novel utterances. Alternative matrix-training procedures should be considered in attempts to optimize the development of…

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…

The nature of word-finding deficits among children with learning disabilities is analyzed; research on the relationship between word-finding ability and reading is reviewed; and classroom implications regarding teacher language, student verbal fluency and flexibility, and student social perception are noted. (CL)

Linguistic and cognitive assessment of children whose home language is not English involves a number of complex issues: minority labeling, the relationship between cognition and bilingualism, "normal" data on bilingual development, and monolingual versus bilingual environment for children experiencing delay. This paper concentrates on reviewing…
