[, Language Acquisition and Language Disorders]

This book presents the current state of knowledge and recent advances on three topics in research on Autism Spectrum Disorder (ASD): the (debated) existence of profiles of abilities, the role of bilingualism, and the impact of interactive technologies. It includes six chapters that cover: a review of morphosyntactic and phonological abilities in monolingual and bilingual children on the autism spectrum; the relation between extra-linguistic factors – intellectual abilities, severity of autism trait – and language skills; an experimental study that aims to identify profiles in children with autism; and current advances on the use of interactive technologies for assessing and training language abilities in ASD. This book will be useful to anyone interested in language acquisition and language development in autism.

The papers comprising this volume focus on a broad range of acquisition phenomena (subject dislocation, structural case, word order, determiners, pronouns, quantifiers and logical words) from different languages and language combinations. These include languages with large numbers of speakers (French, German, Spanish) and less frequently spoken ones (Norwegian, Russian, Swiss-German, Hebrew, Basque and Serbo-Croatian) within different language acquisition scenarios and a wide range of populations. Most contributions adopt a common theoretical background within the generative approach with the aim to advance, discuss and critically analyse other research on first, bilingual and language impaired acquisition. The various sections of this stimulating volume reflect different theoretical and methodological perspectives of current research investigating morphology and syntax and offer diverging interpretations.

This monograph is a theoretical and empirical investigation into the mechanisms and causes of successful and unsuccessful adult second language acquisition.Couched within a generative framework, the study explores how a learner’s first language and the age at which they acquire their second language may contribute to the L2 knowledge that they can ultimately attain. The empirical study focuses on a group of very advanced L2 speakers, and through a series of tests aims to discover what underpins their near mastery of grammatical gender and other grammatical properties.The book explores an account of persistent selective divergence based on the idea that child and adult learners are fundamentally similar, except that in adults the L1 plays the role of a fairly rigid filter of the linguistic input. The impossibility of representing the new target language other than by using the building blocks of the previously established L1 is argued to be the main reason why near but not totally native like language representations are formed and become established in adult L2 learners.

Against the background of the proliferation of the various subdisciplines of language acquisition research over the past decades, this volume aims to enhance the existing but somewhat fragile links between language acquisition and theoretical linguistics. With regard to previous research, the book focuses on the acquisition of syntax and syntactic theory, specifically on Chomskyan Generative Grammar.

This book contains 12 papers contributed by leading scholars in the field of language development, studying variants of the languages which originated on the Iberian peninsula. The contributors examine language development in both typically-developing and language-impaired populations who are learning language in diverse learning conditions, including language contact, as well as monolingual and bilingual Spanish, Catalan, Galician and Euskera. This expansion and diversification of the database for studying language development is important because it creates new opportunities for testing theoretical claims. Our contributors reconsider theoretical claims relating to the purported adult-like nature of young children’s grammars. While some conclude, for example, that children in Mexico possess very adult-like semantic-pragmatic competence in the domain of the pragmatic implicatures associated with existential quantifiers, others conclude that, in particular sociolinguistic registers of Chilean Spanish, children are late to develop adult-like competence in plural marking. Taken together, the contents of the volume illustrate how the linguistic diversity found in the distinct learning conditions in which language develops offers a wealth of opportunities to further our understanding of linguistic and non-linguistic cognitive development.

This book investigates a set of structures characteristic of Chinese speakers' English interlanguage (CIL) in the light of grammatical theory and principles of learnability. As a study of CIL grammar, it illuminates both the theory of interlanguage syntax in general and some specific problems in the acquisition of English by Chinese L1 learners. A set of interrelated structures are investigated, including topicalization, passive, ergative, “tough movement” and existential constructions. The interlanguage is approached through the comparative syntax of the relevant L1 and L2 constructions, combining insights from Chomskyan Universal Grammar and typological research. CIL proves to be permeable to Chinese typological influence and bears topic-prominent characteristics, while showing effects of language universals. A parallel theme of the book is the question of learnability in the context of second language acquisition. The Subset and Uniqueness Principles are adapted to the L2 context so as to account for learning difficulty as well as successful acquisition. Under-generation and over-generation of the interlanguage and target constructions give rise to learnability problems which are formulated in terms of set relations at the level of individual constructions. The Uniqueness Principle is invoked to motivate preemption of overgenerated forms. The interaction of syntax and semantics plays a crucial role in the formulation and resolution of these learnability problems. General conceptual issues raised by the Subset and Uniqueness Principles are also discussed.

This volume includes fourteen papers on the acquisition of Romance languages, eleven of which were presented at the Romance Turn 9, held in Bucharest in September 2018. The studies offer new insights into central issues in the literature, such as syntactic complexity in both typical and impaired language settings, intervention effects, the acquisition of phenomena which involve both syntactic parameters and an external interface, as well as cross-linguistic interference effects. They present novel longitudinal and experimental data on the first language acquisition and second language learning of French, Italian, European and Brazilian Portuguese, Romanian and Spanish. A unique feature of this volume is the focus on the interaction of language specific properties and of factors which are not specific to the faculty of language in the narrow sense, such as data processing, the nature of the input, discourse structure, computational load, sociolinguistic properties, and the development of Theory of Mind.

The present volume provides a cross-linguistic perspective on the development of tense-aspect in L2 acquisition. Data-based studies included in this volume deal with the analysis of a wide range of target languages: Chinese, English, Italian, French, Japanese, and Spanish. Theoretical frameworks used to evaluate the nature of the empirical evidence range from generative grammar to functional-typological linguistics. Several studies focus on the development of past tense markers, but other issues such as the acquisition of a future marker are also addressed. An introductory chapter outlines some theoretical and methodological issues that serves as relevant preliminary reading for most of the chapters included in this volume. Additionally, a preliminary chapter offers a substantive review of first language acquisition of tense-aspect morphology. The analysis of the various languages included in this volume significantly advances our understanding of this phenomenon, and will serve as an important basis for future research.
