All normal humans have the same basic cognitive capacity for language. Nevertheless, the world's languages differ in the kind and number of grammatical options they give their speakers to express themselves with. Sometimes, a language's grammatical constructions may differ in how easy they are for comprehenders to process or how readily speakers will choose them. It has been observed that languages which allow more difficult constructions also tend to allow easier ones, and when a language only allows one option, it tends to allow the easiest to process. This correlation is intuitive: languages tend to give their speakers options that they find easy to use. However, the causal process that underlies it is not well understood. How did the world's languages come to have this convenient property? In this dissertation, I discuss a family of evolutionary models of language change in which processing-efficient variants tend to be selected more frequently, and hence over time have the potential to displace less efficient variants, pushing them out of the language. I begin by showing that a psycholinguistic theory, dependency length minimization, accounts for word ordering preferences in data taken from Old and Middle English just as it does in Present Day English. I then discuss computer simulations of a model of language change which implements this bias, predicting observed word order changes in English. Finally, I present experimental studies of online comprehension in Japanese which not only display evidence for the dependency length bias, but also suggest that comprehenders encode it as part of their knowledge about language, using it to help understand the sentences they receive from their peers.

This book proposes that the fundamental building blocks of syntax are relations between words rather than constituents formed from words.

The unifying topic of this volume is the role of information structure, broadly conceived, as it interacts with the other levels of linguistic description, syntax, morphology, prosody, semantics and pragmatics.

This book combines ideas about the architecture of grammar and language acquisition, processing, and change to explain why languages show regular patterns when there is so much irregularity in their use and so much complexity when there is such regularity in linguistic phenomena. Peter Culicover argues that the structure of language can be understood and explained in terms of two kinds of complexity: firstly that of the correspondence between form and meaning; secondly in the real-time processes involved in the construction of meanings in linguistic expressions. Mainstream generative theory is based on inherent linguistic competence and on the regularities within and across languages, with the exceptional aspects of any language frequently put to one side. But a language's irregular and unique features offer, the author argues, fundamental insights into both the nature of language and the way it is produced and understood. Peter Culicover's new book offers a pertinent and original contribution to key current debates in linguistic theory. It will interest scholars and advanced students of linguists of all theoretical persuasions.

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.

The volume brings together contributions by scholars working in different theoretical frameworks interested in systematic explanation of language change and the interrelation between current linguistic theories and modern analytical tools and methodology. Τhe integrative basis of all work is the special focus on phenomena at the interface of semantics and syntax and the implications of corpus-based, quantitative analyses for researching diachrony.

This book examines the question of whether languages can differ in grammatical complexity and, if so, how relative complexity differences might be measured. The volume differs from others devoted to the question of complexity in language in that the authors all approach the problem from the point of view of formal grammatical theory, psycholinguistics, or neurolinguistics. Chapters investigate a number of key issues in grammatical complexity, taking phonological, morphological, syntactic, and semantic considerations into account. These include what is often called the 'trade-off problem', namely whether complexity in one grammatical component is necessarily balanced by simplicity in another; and the question of interpretive complexity, that is, whether and how one might measure the difficulty for the hearer in assigning meaning to an utterance and how such complexity might be factored in to an overall complexity assessment. Measuring Grammatical Complexity brings together a number of distinguished scholars in the field, and will be of interest to linguists of all theoretical stripes from advanced undergraduate level upwards, particularly those working in the areas of morphosyntax, psycholinguistics, neurolinguistics, and cognitive linguistics.
