This book discusses the first language acquisition of three morphosyntactic mechanisms of transitivity alternation in arctic Quebec Inuktitut. Data derive from naturalistic longitudinal spontaneous speech samples collected over a nine-month period from four Inuit children. Both basic and advanced forms of passive structures are shown to be used productively by Inuktitut-speaking children at an early age relative to English-speaking children, but consistent in age with speakers of non-Indo-European languages reported on in the literature; potential explanations of this difference include frequency of caregiver input and details of language structure. Morphological causatives appear slightly later in the acquisition sequence, and their first instances reflect use of unanalyzed routines. Lexical causatives are present from the earliest ages studied. Evidence of a period of overgeneralization of lexical causatives in one subject at the same time as the morphological causative shows signs of being productively acquired suggests that the seeming overgeneralization may reflect nothing more than as yet unstable use of the morphological causative. Noun incorporation structures are shown to be used productively by Inuktitut-speaking children at an early age relative to Mohawk-speaking children; potential explanations of this difference include details of language structure and relative language use in the environments of the learners. Findings are considered in light of current debates in the literature concerning continuity versus maturation of grammatical structure, and concerning the functional categories available to the child at early stages of acquisition. Data presented argue against late maturation, and suggest that all functional categories may be accessed by the Inuktitut-speaking child early in the acquisition process.

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.

This advanced text for psychology, human development, and education provides students with state-of-the-art overviews of the discipline in an accessible, affordable format. Unique both in the depth of its coverage and in the timeliness of the research that it presents, this comprehensive text conveys the field of child and adolescent development through the voices of scientists who themselves are now shaping the field.

This is the second volume in the series 'Trends in language acquisition research'. The unusual combination in one volume of reports on various different sign languages in acquisition makes this book quite unique.

How and why do all children learn language? Why do some have difficulties while others are early language learners? What are the consequences of early bilingualism? Is it possible to reach native-like competence in a foreign language? Although we still cannot fully answer these questions, research during the last two decades has begun to solve some pieces of the puzzle. This book proposes an interdisciplinary collection of writings from some of the best specialists across several fields in cognitive science, offering a wide sample of recent advances in the study of first language acquisition, bilingualism, second language acquisition, and disorders of oral language. It is addressed to all researchers and students interested in language acquisition, as well as to teachers, clinicians and parents, who will find therein many new findings and varied methodological approaches, as well as challenging questions that are still debated and in need of further research.

This is the first book on the acquisition of Spanish that provides a state-of-the-art comprehensive overview of Spanish morphosyntactic development in monolingual and bilingual situations. Its content is organized around key grammatical themes that form the empirical base of research in generative grammar: nominal and verbal inflectional morphology, subject and object pronouns, complex structures involving movement (topicalizations, questions, relative clauses), and aspects of verb meaning that have consequences for syntax. The book argues that Universal Grammar constrains all instances of language acquisition and that there is a fundamental continuity between monolingual, bilingual, child and adult early grammatical systems. While stressing their similarities with respect to linguistic representations and processes, the book also considers important differences between these three acquisition situations with respect to the outcome of acquisition. It is also shown that many linguistic properties of Spanish are acquired earlier than in English and other languages. This book is a must read for those interested in the acquisition of Spanish from different theoretical perspectives as well as those working on the acquisition of other languages in different contexts.
