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.

Describes experiments involving responses of language disordered children to sentences that can carry directive import. Results indicate that language disordered children are qualitatively like normal children with regard to early response behavior. These children do have more difficulty in generating informing responses and utilizing information…

Comprehension and strategy use of 18 autistic children was compared with that of normal 3- and 4-year olds. Subjects were asked to act out certain syntactic and semantic patterns in two experiments. Autistic children performed below the levels of the normal subjects, suggesting that autism is a semantic/cognitive deficit. (PJM)

Examines the communicative functions served by the lexical usage of normal and language impaired children whose speech was limited to single word utterances. (EKN)

Comparison of language-impaired two- to three-year-olds (N=10) and normal one-year-olds (N=15) matched for expressive language revealed that the language-impaired subjects acquired a greater number of object concepts presented in a no-action condition than the normal children, although language-impaired subjects' extensions of the names to new…
