Presents data on the past and present state of research on the interlanguage hypothesis, with specific attention to its extension to children. Outlines a dual approach to developing a theory of second language acquisition--a macrobehavioral approach and a neurofunctional approach. Finally, problems for the interlanguage hypothesis are discussed.…

Attempts to characterize and contrast aspects of functional organization of neuropsychological systems carrying out primary language acquisition and two types of nonprimary language acquisition: secondary language acquisition and foreign language learning. There appears an intrinsic neurofunctional basis for the greater facility of young children…

The diagnostic problem presented by children without obvious neurological, cognitive, genetic, emotional or environmental basis for their atypical or delayed language development is discussed. One unresolved issue is whether the deficits of such dysphasic children are linguistic or are more fundamental cognitive or perceptuomotor deficits. A…

Linguistics has chosen as its niche the language component of human communication and, naturally enough, the neurolinguist has concentrated on lateralized language systems of the cerebral hemispheres. However, decoding a speaker's total message requires attention to gestures, facial expressions, and prosodic features, as well as other somatic and…

The prelinguistic child's attempts at communication cannot be viewed as rudimentary language. More than cataloguing overt acts, we need to understand the functional character of both language and non-language communication capabilities, and in particular the maturational stages of the internal communication systems that produce overt behavior in…

Reexamines the question of why pattern practice fails by hypothesizing about the information processing activities that they entail. (Author/CFM)

While agreeing with psycholinguistic and neurolinguistic theories that suggest that innate language-related cognitive structures are the basis of language development, the author seeks to establish what it is that is innate and what is meant by innateness in the first place. The author considers the claims of psychological relevance made on behalf…
