The chapters in this volume arise from presentations at a unique conference on typical and atypical language development held in Madison, USA in 2002. This joint meeting of the International Association for the Study of Child Language, and the Symposium for Research in Child Language Disorders brought together – for the first time in such large numbers – researchers from these two distinct but related fields. The week-long schedule of the conference allowed for an in-depth interrogation of their theoretical positions, methodologies and findings. In the contributions to this volume we have put together a carefully selected set of papers which from various perspectives explore the linkage between developmental theory and language impairment, and at the same time illustrate the effects of distinct conditions – hearing loss, autism, Down syndrome, Williams syndrome and specific language impairment – on the communication abilities of affected individuals. An introductory chapter, and a detailed summary which picks up recurring themes in the chapters, complete the volume.

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.

Prominent researchers from the US, Mexico, Chile, Colombia and Spain contribute experimental reports on language development of children who are acquiring Spanish. The chapters cover a wide range of dimensions in acquisition: comprehension and production; monolingualism and bilingualism; typical development, children who are at risk and children with language disorders, phonology, semantics, and morphosyntax. These studies will inform linguistic theory development in clinical linguistics as well as offer insights on how language works in relation to cognitive functions that are associated with when children understand or use language. The unique data from child language offer perspectives that cannot be drawn from adult language. The first part is dedicated to the acquisition of Spanish as a first or second language by typically-developing children, the second part offers studies on children who are at risk of language delays, and the third part focuses on children with specific language impairment, disorders and syndromes.

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

Language Disorders in Bilingual Children and Adults, Third Edition, provides speech-language pathologists, advanced students in communication disorders programs, and clinical language researchers with information needed to formulate and respond to questions related to effective service delivery to bilingual children and adults with suspected or confirmed language disorders. The bilinguals of interest represent varying levels of first and second language proficiency across the lifespan. That is, bilingualism is not determined here by proficiency in each language, but rather by the individual's experience or need for two languages. In separate chapters, the book synthesizes the literature on bilingual children and adults with typical and atypical language skills. These chapters give the reader a deep understanding of the multiple factors that affect language development and disorders in those who rely on two languages for meaningful interactions. Chapters on assessment and intervention issues and methods are then presented for each population. For children, the text focuses on developmental language disorder but also discusses secondary language disorders (such as autism spectrum disorder) in bilingual populations. For adults, the focus is on aphasia, with additional discussion of dementia, traumatic brain injury, and right hemisphere disorder. Although child and adult, typical and atypical populations are presented separately, all are considered within a unifying Dynamic Interactive Processing perspective and within a new Means-Opportunities-Motives framework for understanding language disorders in bilinguals. This broad theoretical framework emphasizes interactions between social, cognitive, and communicative systems to form the basis for very practical implications related to assessment and intervention. This third edition has been completely updated to reflect the current research on bilingual populations and the best practices for working with them. Studies at the intersection of bilingualism and language disorders have expanded to include additional disorders and new language combinations. The authors synthesize the current literature and translate it for clinical use. New to the Third Edition • Coauthors Kerry Danahy Ebert, PhD, CCC-SLP and Giang Thuy Pham, PhD, CCC-SLP • Updated literature review and references to reflect new research on bilingualism, cultural competence, cognitive advantages and clinical practice with linguistically diverse populations • Case studies on assessment with bilingual children and adults • Additional tables and figures summarizing key information • Available evidence on additional child and adult language disorders in bilinguals • Updated extension activities and resource supplement

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.

Language Development From Theory to Practice provides a survey of key topics in language development, including research methods, theoretical perspectives, and major language milestones from birth to adolescence and beyond, and language diversity and language disorders. Each chapter bridges language development theory and practice by providing students with a theoretical and scientific foundation to the study of language development. The authors emphasize the relevance of the material to students’ current and future experiences in clinical, educational, and research settings; emphasize multicultural considerations and how they affect language development; focus on using evidence-based practices for making educational and clinical decisions; show the relevance of a multidisciplinary perspective on the theory and practice of language development; and include a number of outstanding pedagogical features to motivate and engage students.
