This book explores a much-debated area of language acquisition: the omission by young children of direct objects in a sentence.

Differential Object marking (DOM), a linguistic phenomenon in which a direct object is morphologically marked for semantic and pragmatic reasons, has attracted the attention of several subfields of linguistics in the past few years. DOM has evolved diachronically in many languages, whereas it has disappeared from others; it is easily acquired by monolingual children, but presents high instability and variability in bilingual acquisition and language contact situations. This edited collection contributes to further our understanding of the nature and development of DOM in the languages of the world, in acquisition, and in language contact, variation, and change. The thirteen chapters in this volume present new empirical data from Estonian, Spanish, Turkish, Korean, Hindi, Romanian and Basque in different acquisition contexts and learner populations. They also bring together multiple theoretical and methodological perspectives to account for the complexity and dynamicity of this widespread linguistic phenomenon.

This book offers a new contribution to the debate concerning the “real time acquisition” of grammar in First Language Acquisition Theory. It combines detailed and quantitative observations of object placement in Dutch and Italian child language with an analysis that makes use of the Modularity Hypothesis. Real time development is explained by the interaction between two different modules of language, namely syntax and pragmatics. Children need to build up knowledge of how the world works, which includes learning that in communicating with someone else, one must realize that speaker and hearer knowledge are always independent. Since the syntactic feature referentiality can only be marked if this (pragmatic) distinction is made, and assuming that certain types of object placement (such as scrambling and clitic placement) are motivated by referentiality, it follows that the relevant syntactic mechanism is dependent on the prior acquisition of a pragmatic distinction.

In this final volume in the series, the contributors attempt to "expand the contexts" in which child language has been examined crosslinguistically. The chapters build on themes that have been touched on, anticipated, and promised in earlier volumes in the series. The study of child language has been situated in the disciplines of psychology and linguistics, and has been most responsive to dominant issues in those fields such as nativism and learning, comprehension and production, errors, input, and universals of morphology and syntax. The context has primarily been that of the individual child, interacting with a parent, and deciphering the linguistic code. The code has been generally treated in these volumes as a system of morphology and syntax, with little attention to phonology and prosody. Attention has been paid occasionally to the facts that the child is acquiring language in a sociocultural setting and that language is used in contexts of semantic and pragmatic communication. In addition, there has been a degree of attention paid to the interactions between language and cognition in the process of development. As for individual differences between children, they have been discussed in those studies where they could not be avoided, but such variation has rarely been the focus of systematic attention. Differences between individual languages have been of great interest, but these differences have not often been placed in a framework of systematic typological variation. And although languages and their grammars change over time, the focus of attention on the individual child learner has generally led to neglect of explanatory principles that are best found on the level of linguistic diachrony, rather than the level of innate ideas or patterns of learning and cognition in the individual child. The chapter authors seek to explore these neglected contexts in more depth.

An introduction to the study of children's language development that provides a uniquely accessible perspective on generative/universal grammar–based approaches. How children acquire language so quickly, easily, and uniformly is one of the great mysteries of the human experience. The theory of Universal Grammar suggests that one reason for the relative ease of early language acquisition is that children are born with a predisposition to create a grammar. This textbook offers an introduction to the study of children's acquisition and development of language from a generative/universal grammar–based theoretical perspective, providing comprehensive coverage of children's acquisition while presenting core concepts crucial to understanding generative linguistics more broadly. After laying the theoretical groundwork, including consideration of alternative frameworks, the book explores the development of the sound system of language—children's perception and production of speech sound; examines how words are learned (lexical semantics) and how words are formed (morphology); investigates sentence structure (syntax), including argument structure, functional structure, and tense; considers such “nontypical” circumstances as acquiring a first language past infancy and early childhood, without the abilities to hear or see, and with certain cognitive disorders; and studies bilingual language acquisition, both simultaneously and in sequence. Each chapter offers a summary section, suggestions for further reading, and exercises designed to test students' understanding of the material and provide opportunities to practice analyzing children's language. Appendixes provide charts of the International Phonetic Alphabet (with links to websites that allow students to listen to the sounds associated with these symbols) and a summary of selected experimental methodologies.

Teachers are often told that new teaching methods and materials are 'based on the latest research'. But what does this mean in practice? This book introduces you to some of the language acquisition research that will help you not just to evaluate existing materials, but also to adapt and use them in a way that fits what we currently understand about how languages are learned.

The research presented in this volume covers first language acquisition, second language acquisition, language heritage and language impairment. Papers in this collection use a variety of experimental methods, such as eye-tracking, elicitation tasks, production tasks administered off-line and untimed, transcriptions of spontaneous speech, production elicitation, Truth Value Judgement tasks, standardized tests and multiple choice tasks. The studies included in this book try to cover most of the methods used in first and second language acquisition in typical and atypical populations. This book will be useful for linguists, speech therapists, and psycholinguists working on first, second and impaired language acquisition.

The Fundamentally Simple Logic of Language: Learning a Second Language with the Tools of the Native Speaker presents a data-driven approach to understanding how native speakers do not use subject and direct object to process language. Native speakers know who does what in a sentence by applying intuitively two simple inferences that are argued to be part of universal grammar. The book explains and exemplifies these two inferences throughout. These two inferences explain the native speaker’s ease of acquisition and use, and answer difficult questions for linguistics (transitivity, case, semantic roles) in such a way that undergraduate students and second language learners can understand these concepts and apply them to their own language acquisition. While Spanish is used as the primary example, the theory can be applied to many other languages. This book will appeal to teachers and learners of any second language, as well as linguists interested in second language acquisition, in second language teaching, and in argument structure.

Understanding how people learn and fail to learn second and foreign languages is increasingly recognised as a critical social and psycholinguistic issue. Second languages are vitally important to diverse groups of people, ranging from refugees to college students facing foreign language requirements. This book provides a synthesis of empirical findings on second and foreign language learning by children and adults, emphasising the design and execution of appropriate research.
