Highlighting the close relationship between linguistic explanation and learnability, Bruce Tesar and Paul Smolensky examine the implications of Optimality Theory (OT) for language learnability. Highlighting the close relationship between linguistic explanation and learnability, Bruce Tesar and Paul Smolensky examine the implications of Optimality Theory (OT) for language learnability. They show how the core principles of OT lead to the learning principle of constraint demotion, the basis for a family of algorithms that infer constraint rankings from linguistic forms. Of primary concern to the authors are the ambiguity of the data received by the learner and the resulting interdependence of the core grammar and the structural analysis of overt linguistic forms. The authors argue that iterative approaches to interdependencies, inspired by work in statistical learning theory, can be successfully adapted to address the interdependencies of language learning. Both OT and Constraint Demotion play critical roles in their adaptation. The authors support their findings both formally and through simulations. They also illustrate how their approach could be extended to other language learning issues, including subset relations and the learning of phonological underlying forms.
Anjum P. Saleemi argues that the acquisition of language as a cognitive system can properly be understood by pairing the formal approach to learning, often known as learnability theory, with Chomsky's theory of Universal Grammar and its claim that human language is innately constrained, with some predefined space for variation. Focusing on specific areas of syntax, such as binding theory and the null subject parameter, Dr Saleemi unites learnability theory's methodology with Chomsky's principles-and-parameters model, and construes acquisition as a function of linguistic principles with largely domain-specific learning procedures, mediated by environmental input. The aim of this study is to show that a self-contained linguistic theory cannot by itself be psychologically plausible, but depends on a compatible theory of learning which embraces developmental as well as formal issues.
The impetus for this volume developed from the 1982 University of Western Ontario Learnability Workshop, which was organized by the editors and sponsored by that University's Department of Philosophy and the Centre for Cognitive Science. The volume e~plores the import of learnability theory for contemporary linguistic theory, focusing on foundational learning-theoretic issues associated with the parametrized Government-Binding (G-B) framework. Written by prominent re searchers in the field, all but two of the eight contributions are pre viously unpublished. The editor's introduction provides an overview that interrelates the separate papers and elucidates the foundational issues addressed by the volume. Osherson, Stob, and Weinstein's "Learning Theory and Natural Language" first appeared in Cognition (1984); Matthews's "The Plausi bility of Rationalism" was published in the Journal of Philosophy (1984). The editors would like to thank the publishers for permission to reprint these papers. Mr. Marin Marinov assisted with the preparation of the indices for the volume. VB ROBERT 1. MATTHEWS INTRODUCTION: LEARNABILITY AND LINGUISTIC THEORY 1. INTRODUCTION Formal learning theory, as the name suggests, studies the learnability of different classes of formal objects (languages, grammars, theories, etc.) under different formal models of learning. The specification of such a model, which specifies (a) a learning environment, (b) a learn ing strategy, and (c) a criterion for successful learning, determines (d) a class of formal objects, namely, the class that can be acquired to the level of the specified success criterion by a learner implementing the specified strategy in the specified enviroment.
A classic book about language acquisition and conceptual structure, with a new preface by the author, "The Secret Life of Verbs." Before Steven Pinker wrote bestsellers on language and human nature, he wrote several technical monographs on language acquisition that have become classics in cognitive science. Learnability and Cognition, first published in 1989, brought together two big topics: how do children learn their mother tongue, and how does the mind represent basic categories of meaning such as space, time, causality, agency, and goals? The stage for this synthesis was set by the fact that when children learn a language, they come to make surprisingly subtle distinctions: pour water into the glass and fill the glass with water sound natural, but pour the glass with water and fill water into the glass sound odd. How can this happen, given that children are not reliably corrected for uttering odd sentences, and they don't just parrot back the correct ones they hear from their parents? Pinker resolves this paradox with a theory of how children acquire the meaning and uses of verbs, and explores that theory's implications for language, thought, and the relationship between them. As Pinker writes in a new preface, "The Secret Life of Verbs," the phenomena and ideas he explored in this book inspired his 2007 bestseller The Stuff of Thought: Language as a Window into Human Nature. These technical discussions, he notes, provide insight not just into language acquisition but into literary metaphor, scientific understanding, political discourse, and even the conceptions of sexuality that go into obscenity.
Suzanne Flynn and Wayne O'Neil Massachusetts Institute of Technology I. INTRODUCTION The theory of Universal Grammar (UG) as explicated e. g. in Chomsky, 1986, has led to explosive developments in the study of natural language as well as to significant advances in the study of first language (L I) acquisition. Most recently. the theory of UG has led to important theore tical and empirical advances in the field of adult second language (L2) acquisition as well. The principle impetus for this development can be traced to the work in linguistics which shifted the study "from behavior or the products of behavior to states of the mind/brain that enter into behavior" (Chomksy. 1986:3). Grammars within this framework are conceived of as theoretical accounts of "the state of the mind/brain of the person who knows a particular language" (Chomsky. 1986:3). Research within fields of language acquisition seeks to isolate and specify the properties of the underlying competence necessary for language learning. Full development of a theory of UG demands study and understanding of the nature of both the formal properties of language and of the language acquisition process itself. However. while there is a tradition of debate and dialogue established between theoretical linguistics and Ll acquisition research. relatively few connections have been made between linguistic theory and L2 acquisition research.
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 book explores one of the central theoretical problems in linguistics: learnability. Written by four researchers in linguistics, psychology, computer science, and cognitive science, it sheds light on the problems of learnability and language, and their implications for key theoretical linguistics and the study of language acquisition.
In this influential study, Steven Pinker develops a new approach to the problem of language learning. Now reprinted with new commentary by the author, this classic work continues to be an indispensable resource in developmental psycholinguistics.
Teachability and Learnability across Languages addresses key issues in second, foreign and heritage language acquisition, as well as in language teaching. Focusing on a Processability Theory perspective, it brings together empirical studies of language acquisition, language teaching, and language assessment. For the first time, a research timeline for the role of instruction in language learning is presented, showing how the field of second language acquisition (SLA) research has developed over the last four decades since Pienemann's work on learnability and syllabus construction over the 1980s. The book includes studies of child and adult second as well as foreign language acquisition research, covering a wide range of target languages including English, German, Hungarian, Japanese, Norwegian, Polish, Spanish, Swedish, and Turkish. In addition, future extensions of PT are discussed. This volume is designed for advanced students in international programs of SLA and Applied Linguistics as well as for SLA researchers and second and foreign language teachers.
This handbook provides a critical guide to the most central proposition in modern linguistics: the notion, generally known as Universal Grammar, that a universal set of structural principles underlies the grammatical diversity of the world's languages. Part I considers the implications of Universal Grammar for philosophy of mind and the philosophy of language, and examines the history of the theory. Part II focuses on linguistic theory, looking at topics such as explanatory adequacy and how phonology and semantics fit into Universal Grammar. Parts III and IV look respectively at the insights derived from UG-inspired research on language acquisition, and at comparative syntax and language typology, while part V considers the evidence for Universal Grammar in phenomena such as creoles, language pathology, and sign language. The book will be a vital reference for linguists, philosophers, and cognitive scientists.
