This critical history of research on acquired language deficits (aphasias) demonstrates the usefulness of linguistic analysis of aphasic syndrome for neuropsychology, linguistics, and psycholinguistics. Drawing on new empirical studies, Grodzinsky concludes that the use of grammatical tools for the description of the aphasias is critical. The selective nature of these deficits offers a novel view into the inner workings of our language faculty and the mechanisms that support it.In contrast to other proposals that the left anterior cerebral cortex is crucial for all syntactic capacity, Grodzinsky's discoveries support his theory that this region is necessary for only a small component of the human language faculty. On this basis he provides a detailed explanation for many aphasic phenomena - including a number of puzzling cross-linguistic aphasia differences - and uses aphasic data to evaluate competing linguistic theories.Yosef Grodzinsky is a member of the psychology faculty at Tel Aviv University. "Theoretical Perspectives on Language Deficits" is included in the series Biology of Language and Cognition, edited by John P. Marshall. A Bradford Book.

Research into child language development is being conducted more extensively, by more people, and in more countries throughout the world than at any point in the past. We now know more than we ever did before about the linguistic, cognitive, neurobio logical, and social capacities that children bring to their language learning task, as well as the ways in which these capacities interact with a whole range of factors present in the child's environment throughout the learning process, not least the particular character istics of the language or languages to which the child is exposed. Far from inducing a sense of complacency, this new knowledge seems instead to create an even stronger impetus to know more. This is partly because of the new and unforeseen questions it raises and partly because of competition between different theories to provide the best explanation of the phenomenon, and which in turn engender different methods of enquiry. This volume addresses many of the key issues which are currently exercising the minds of child language researchers, and which are likely to motivate research for some years to come. The chapters included here-all previously unpublished-present a great deal of new data and address a range of theoretical issues from a variety of perspectives.

Children with Specific Language Impairment covers all aspects of SLI, including its history, possible genetic and neurobiological origins, and clinical and educational practice.

Developmental language disorders (DLD) occur when a child fails to develop his or her native language often for no apparent reason. Delayed development of speech and/or language is one of the most common reasons for parents of preschool children to seek the advice of their family doctor. Although some children rapidly improve, others have more persistent language difficulties. These long-term deficits can adversely affect academic progress, social relationships and mental well-being.Although DLDs are common, we are still a long way from understanding what causes them and how best to.

The relationship between language and thought in bilinguals is examined in the light of evidence from pathology."--BOOK JACKET.

This unique, edited book bridges studies in language disorders and linguistic theory with timely contributions from leading scholars in language development. It presents an attempt to define Specific Language Impairment, relating it to children of normal and disordered language capabilities. The chapter presentations examine language development across a variety of populations of children, from those with Specific Language Impairment to second language learners. The contributors discuss criteria for the definition of SLI, compare and contrast SLI with profiles of children with other disorders and dialects, and offer a comprehensive look at the Whole Human Language, which ties together spoken and signed languages. Methodological concerns that affect the credibility and generalizability of the findings are discussed and controversies between opposing linguistic approaches to language acquisition are presented. The conceptual thread that gradually reveals itself as the chapters unfold is a theoretical issue of central importance to cognitive theory, as well as to our understanding of the biological correlates of language--it concerns the variability that linguistic competence can manifest in children under different biological conditions and life circumstances. Language Competence Across Populations: Toward a Definition of Specific Language Impairment is an essential volume for advanced students and scholars in linguistics and psychology who have an interest in language acquisition and language disorders, as well as for the clinical professionals dealing with children with language impairments.
