By combining theoretical analysis and empirical investigation, this monograph investigates the status of interfaces in Minimalist linguistic theory, second language acquisition and native language attrition. Two major questions are currently under debate: (1) what exactly makes a linguistic phenomenon an ‘interface phenomenon’, and (2) what is the specific role that the interfaces play in explaining language loss and persistent problems in second language acquisition? Answers to these questions are provided by a theoretical examination of the role that economy and computational efficiency play in recent Minimalist models of the language faculty, as well as by evidence obtained in two empirical studies examining the acquisition and attrition of two interface phenomena: Spanish subject realization and word order variation. The result is a new definition of ‘interface phenomena’ which deemphasizes syntactic complexity and focuses on the effect of interface interpretive conditions on syntactic structure. This work also shows that representational deficits cannot be ruled out in the acquisition and attrition of interface structures.

Second language acquisition (SLA) and language testing (LT) research have largely been viewed as distinct areas of inquiry in applied linguistics. This book provides a fresh look at areas of common interest to both SLA and LT research, and ways in which research in these two areas of applied linguistics can be fruitfully integrated.

This volume is a collection of papers presented at the 12th Generative Approaches to Language Acquisition Conference held at the University of Nantes, France, in 2015. Language acquisition, a field of inquiry that has witnessed continuous growth during the past four decades, is central to building a detailed understanding of the human amazing capacity to develop language. The papers gathered here reflect the current research in the field of first, second and heritage language acquisition, addressing a variety of topics in syntax, semantics, phonology and their interfaces, from a wide range of languages such as Tashlhiyt Berber, English, German, Italian, Japanese, Mandarin, European Portuguese, Heritage Portuguese, Romanian, Serbian, Heritage Sign Language, and Yudja. This volume will thus serve as a valuable reference guide to all scholars interested in (first/second/bilingual) language acquisition, multilingualism, heritage languages, sign language, language pathology and impairment, and experimental research in linguistics.

This book provides a snapshot of the field of language acquisition at the beginning of the 21st Century. It represents the multiplicity of approaches that characterize the field and provides a review of current topics and debates, as well as addressing some of the connections between sub-fields and possible future directions for research.

'The Oxford Handbook of Linguistic Interfaces' explores how the core components of the language faculty interact. This book shows how these interactions are reflected in linguistic and cognitive theory, considers what they reveal, and looks at their reflections in expression and communication.

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.

In this book, I address several issues of child linguistic development from the perspective of the syntax -discourse interface. Traditionally, language acquisition research has focused on the development of one of the linguistic modules, e.g. acquisition of syntax, morphology or phonology. While this approach can be viewed as fruitful in some cases, there is a number of linguistic phenomena whose explanation depends on the interaction of different modules and, therefore, different domains of linguistic knowledge. A typical example is pronominal anaphora: It can be shown that to correctly use pronominal elements, normal adult speakers must possess both syntactic and pragmatic knowledge, and that these kinds of knowledge must interact with each other. With regard to the language acquisition process, such phenomena suggest a somewhat different approach to the language acquisition research. Indeed, if some experimental studies show that children make errors in the construction under investigation, it will be necessary to consider these results from the point of view of the interaction of the different domains of linguistic knowledge involved in their interpretation. In other words, if this particular construction requires the integration of, for example, syntactic and discourse-based knowledge, children's errors may, in principle, be due to their lack of the former, the latter, or both kinds of knowledge, and cannot be taken as direct evidence for the "underdeveloped" status of just one of them.

One of the most striking trends across linguistic research in recent years has been the examination of the interfaces between the various subcomponents of the language faculty. Yet, approaches to these interfaces across different theoretical frameworks differ substantially. This volume pulls together research into Morphology and its interfaces from researchers employing a variety of different theoretical and methodological perspectives: Morphology is a diverse field, and rather than aiming to collect works sharing a particular approach or framework of assumptions, this collection instead captures the diversity and provides an overview of the state of the research field while also addressing particular empirical phenomena with up-to-date analyses. The articles collected provide case studies from a diverse variety of languages revealing properties of the interfaces that morphology shares with syntax, semantics, phonology, and the lexicon, while the volume's inclusive cross-theoretical approach will serve to introduce readers to the findings of alternative frameworks and methodologies.

This volume is an important contribution to the theoretical and empirical study of the interactions of grammatical components in Chinese and other languages. With contributions by Edward L. Keenan, Henk van Riemsdijk, Alain Rouveret, and scholars in Chinese Linguistics, this volume investigates the common structural properties that may be considered as possible candidates for UG. It addresses syntactic and semantic issues such as anaphora universals over non-isomorphic languages, the role that the forces of attraction and repulsion play in the grammar of natural languages, computational and semantic aspects of resumption, the dichotomy between inner and outer reflexive adverbials, system repairing strategies at interfaces, the v-copy construction in Chinese, the scope of disjunction, interactions between focus, negation and event quantification, null object constructions and VP-Ellipsis, child language acquisition of nominal structure, word order and referentiality as well as second language acquisition of interface properties in Chinese double NP constructions. This volume will be of interest to students and researchers of syntax, semantics, theoretical linguistics, and language acquisition, as well as scholars in Chinese linguistics.

The present collection offers fresh perspectives on the lexicon-syntax interface, drawing on novel data from South Asian languages like Bangla, Hindi-Urdu, Kashmiri, Kannada, Malayalam, Manipuri, Punjabi, and Telugu. It covers different phenomena like adjectives, nominal phrases, ditransitives, light verbs, middles, passives, causatives, agreement, and pronominal clitics, while trying to settle the theoretical tensions underlying the interaction of the lexicon with the narrow syntactic component. All the chapters critically survey previous analyses in detail, suggesting how these may or may not be extended to South Asian languages. Novel explanations are proposed, which handle not only the novel data presented here, but also pave alternative ways to look at issues of minimalist architecture.
