Past studies of autistic children's memory for linguistic materials have shown that autistics have a special linguistic coding difficulty. Because the autistic deficit stems from a failure to use semantic and syntactic knowledge or from a failure to acquire such forms, future research should explore the mechanics underlying this deficit.

A review of the literature on children with language disorders characterized by semantic and pragmatic impairments suggests that some of these conditions may stem from the same fundamental cognitive and interpersonal difficulties found in early childhood autism. A summary of recent research and theory in autism is also presented. (Author/DB)

The concept of language learning disability is discussed in terms of such language components as phonology, morphology, syntax, semantics, and pragmatics; input and output dimensions of language performance; information processing; and the social construction of meaning. (DB)

A model of language abilities in matrix form is described in which areas of language ability are defined in terms of the effects of receptive and expressive language processes on four linguistic levels: phonology, morphology, syntax, and semantics. (Author)

This response to EC 604 058 argues that Marc Fey's emphasis on language organization at the morpheme and word level is not efficacious with preschool children who show phonological delay and delayed semantic-syntactic development. A model of verbal communication which unites phonetic, phonological, and higher organizational levels and related…
