Language Competence Across Populations
Toward a Definition of Specific Language Impairment
Edited by Yonata Levy, Jeannette C. Schaeffer
Published May 3rd 2013 by Psychology Press – 480 pages
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.
"Schaeffer correctly describes the book as one that keeps alive the interaction and exchange of information between models of linguistic theory and cross-linguistic/cross-learner data studies. I found the book to do more than this….provides a good demonstration of the progress being made in the study of the SLI and of other childhood language disorders."
—International Journal of Language and Communication Disorders
"One of the best features of this text is the way that the authors refer to the other chapters within the book….For those who like to keep abreast of developments in the research in a broader sense this book would prove a very interesting read."
—Child Language Teaching and Therapy
"It [Language Competence Across Populations] brings together information on language impairments in a way that will broaden the horizons of many who read it. Ideas introduced are supported by a wealth of references that will assist this process….It is both thought-provoking and informative for everyone who works in the field…For those who like to keep abreast of developments in the research in a broader sense this book would prove a very interesting read."
—Child Language Teaching and Therapy
"The insights gained into the nature of SLI and other developmental language disorders are carefully scrutinized, and most of the authors call for a much-needed and bold revision of current definition standards for a more comprehensive understanding of what SLI is, and of what its causes may be.The theoretical and methodological implications of these studies will be of interest to a wide audience ranging from linguists and psychologists working in the field of language impairments to clinicians working with patients."
