Language Acquisition and Language Disorders

This cross-linguistic volume innovates research of the acquisition of diminutives in the inflecting-fusional languages Lithuanian, Russian, Croatian, Greek, Italian, Spanish, German and Dutch, the agglutinating languages Turkish, Hungarian and Finnish and in the introflecting Hebrew. These languages differ in various aspects relevant for the acquisition of diminutives and the development of pragmatics in early child language. Diminutive formation often tends to be the first pattern of word formation to emerge. The main reason for this seems to lie in the pragmatic functions of endearment, empathy, and sympathy, which make diminutives particularly appropriate for child-centred communication. A main topic of this book is the relation of emergence and early development between diminutives and other categories of word formation and inflection. The greater degree of morphological productivity and transparency, as well as phonological saliency, favors the use of diminutives. In this case diminutives may facilitate the acquisition of inflection.

This book presents a thorough description of morphosyntactic knowledge developed by learners of French in four different learning situations — first language (L1) acquisition, second (L2) language acquisition, bilingualism, and acquisition by children with Specific Language Impairment — within the theoretical framework of generative grammar. This approach allows for multiple comparisons across acquisition contexts, which provides the reader with invaluable insights into the nature of the acquisition process. The book is divided into four parts each dealing with a major morphosyntactic domain of acquisition: the verbal domain, the pronominal domain, the nominal domain, and the CP domain. Each part contains four chapters, the first one presenting an overview of the basic facts and analyses of the relevant properties of French, and the next three focusing on the different acquisition contexts. This book will be useful to anyone interested in the acquisition of French and in language development in general. It is also meant to stimulate cross-linguistic research from a theoretical perspective.

A major contribution to the study of language acquisition and language development inspired by theoretical linguistics has been made by research on the acquisition of Italian syntax. This book offers an updated overview of results from theory-driven experimental and corpus-based research on the acquisition of Italian in different modes (monolingual, early and late L2, SLI, etc.), as well as exploring possible developments for future research. The book focuses on experimental studies which address research questions generated by linguistic theory, providing a detailed illustration of the fruitful interaction between linguistic theorizing and developmental studies. The authors are leading figures in theoretical linguistics and language acquisition; their own work is featured in the research presented here. Students and advanced researchers will benefit from the systematic review offered by this book and the critical assessment of the field that it provides.

This work is based on an investigation of language acquisition process, particularly in regard to syntax, among Mauritian children learning to speak Mauritian Creole as their first language. As such, it is the first major study of the development of child grammar in a Creole context. Mauritian Creole, in common with many Creole languages, emerged under extreme conditions and, as an isolating language, Mauritian Creole is typologically different from languages where syntax is predominantly tied to morphology. There is thus an opportunity to broaden perspectives on language acquisition since until now most work has focused on languages such as English, French, German, Italian. The analysis proceeds within the GB framework of generative grammar, and discussion emanates from psycholinguistic, sociolinguistic and theoretical linguistic viewpoints. The data also provide a means for evaluating Bickerton's theory, especially his conclusion that the acquisition of radical Creoles takes place with fewer errors than is the case for other languages, given that Creole languages are in harmony with the 'Bioprogram'.

This monograph is the first study of the acquisition of Swahili as a first language. It focuses on the acquisition of inflectional affixes, with a particular emphasis on subject agreement and tense. Other inflectional affixes are also investigated, including object agreement and mood. The study surveys the adult dialect in question, Nairobi Swahili, discussing social, phonological, morphological and syntactic properties. Data, analyses and copious examples are presented of the naturalistic speech of four Swahili speaking children. The data are tested against six influential theories of child language, and the results show that processing and metrical theories of telegraphic speech fail to account for the observed patterns, while grammatical theories of child language fair significantly better. The data and analyses presented in this book are indispensable for linguists and psychologists interested in the acquisition of inflectional material and other cross-linguistic properties of child language.

This volume includes a selection of papers that address a wide range of acquisition phenomena from different Romance languages and all share a common theoretical approach based on the Principles and Parameters theory. They favour, discuss and sometimes challenge traditional explanations of first and second language acquisition in terms of maturation of general principles universal to all languages. They all depart from the view that language acquisition can be explained in terms of learning language specific rules, constraints or structures. The different parts into which this volume is organized reflect different approaches that current research has offered, which deal with issues of development of reflexive pronouns, determiners, clitics, verbs, auxiliaries, inflection, wh-movement, ressumptive pronouns, topic and focus, mood, the syntax/discourse interface, and null arguments.

Volume 1 of Approaches to Bootstrapping focuses on early word learning and syntactic development with special emphasis on the bootstrapping mechanisms by which the child using properties of the speech input enters the native linguistic system. Topics discussed in the area of lexical acquisition are: cues and mechanisms for isolating words in the input; special features of motherese and their role for early word learning; the determination of first word meanings; memory and related processing capacities in early word learning and understanding; and lexical representation and lexical access in early language production.

The papers on syntactic development deal with the acquisition of grammatical prosodic features for learning language specific syntactic regularities.Volume 2 of Approaches to Bootstrapping focuses on the interaction between the development of prosodic and morphosyntactic knowledge as evidenced in the early speech of Dutch, English, German, Portugese, Spanish, Danish, Islandic, and Swedish children shedding new light on the relation between universal and language specific aspects of language acquisition. Another section of this volume deals with new approaches to language acquisition using ERP- techniques. The papers discuss in detail the relation between the development of language skills and changes in neurophysiological aspects of the brain. The potentials of these techniques for the development of new tools for an early diagnosis of children who are at risque for developmental language disorders are also pointed out.

The closing section contains a synopsis of interactionist approaches to language acquisition, a discussion of the genetic and experiential origin of primitive linguistic elements in acquisition, and a discussion of structural and developmental aspects of bird song in comparison to human language.

The two volumes making up Approaches to Bootstrapping present a state-of-the art interdisciplinary and cross-linguistic overview of recent developments in first language acquisition research.

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.

The cross-linguistic differences documented in studies of relative clause attachment offer an invaluable opportunity to examine a particular aspect of bilingual sentence processing: Do bilinguals process their two languages as if they were monolingual speakers of each? This volume provides a review of existing research on relative clause attachment, showing that speakers of languages like English attach relative clauses differently than do speakers of languages like Spanish. Fernández reports the findings of an investigation with monolinguals and bilinguals, tested using speeded ("on-line") and unspeeded ("off-line") methodology, with materials in both English and Spanish. The experiments reveal similarities across the groups when the procedure is speeded, but differences with unspeeded questionnaires: The monolinguals replicate the standard cross-linguistic differences, while bilinguals have language-independent preferences determined by language dominance — bilinguals process stimuli in either of their languages according to the general preferences of monolinguals of their dominant language.

The term “crosscurrent” is defined as “a current flowing counter to another.” This volume represents crosscurrents in second language acquisition and linguistic theory in several respects. First, although the main currents running between linguistics and second language acquisition have traditionally flowed from theory to application, equally important contributions can be made in the other direction as well. Second, although there is a strong tendency in the field of linguistics to see “theorists” working within formal models of syntax, SLA research can contribute to linguistic theory more broadly defined to include various functional as well as formal models of syntax, theories of phonology, variationist theories of sociolinguists, etc. These assumptions formed the basis for a conference held at Stanford University during the Linguistic Institute there in the summer of 1987. The conference was organized to update the relation between second language acquisition and linguistic theory. This book contains a selection of (mostly revised and updated) papers of this conference and two newly written papers.
