How and why do all children learn language? Why do some have difficulties while others are early language learners? What are the consequences of early bilingualism? Is it possible to reach native-like competence in a foreign language? Although we still cannot fully answer these questions, research during the last two decades has begun to solve some pieces of the puzzle. This book proposes an interdisciplinary collection of writings from some of the best specialists across several fields in cognitive science, offering a wide sample of recent advances in the study of first language acquisition, bilingualism, second language acquisition, and disorders of oral language. It is addressed to all researchers and students interested in language acquisition, as well as to teachers, clinicians and parents, who will find therein many new findings and varied methodological approaches, as well as challenging questions that are still debated and in need of further research.

Language acquisition is a human endeavor par excellence. As children, all human beings learn to understand and speak at least one language: their mother tongue. It is a process that seems to take place without any obvious effort. Second language learning, particularly among adults, causes more difficulty. The purpose of this series is to compile a collection of high-quality monographs on language acquisition. The series serves the needs of everyone who wants to know more about the problem of language acquisition in general and/or about language acquisition in specific contexts.

This volume aims to provide a broad view of second language acquisition within a comparative perspective that addresses results concerning adult and child learners across a variety of source and target languages. It brings together contributions at the forefront of language acquisition research that consider a wide range of open questions: What are the precise mechanisms underlying acquisition? How can we characterize learners’ initial state and predict their degree of final achievement? What role do specific (typological) properties of source and target languages play? How does fossilization occur? How does the relative complexity of cognitive systems in adult and child learners affect acquisition? Does language learning influence cognitive organization? Can language learning shed light on our general understanding of human language and language processing?

The past 15 years have witnessed an increasing interest in the comparative study of language and music as cognitive systems. Language and music are uniquely human traits, so it is not surprising that this interest spans practically all branches of cognitive science, including psychology, computer science, linguistics, cognitive neuroscience, and education. Underlying the study of language and music is the assumption that the comparison of these two domains can shed light on the structural and functional properties of each, while also serving as a test case for theories of how the mind and, ultimately, the brain work. This book presents an interdisciplinary study of language and music, bringing together a team of leading specialists across these fields. The volume is structured around four core areas in which the study of music and language has been particularly fruitful: (i) structural comparisons, (ii) evolution, (iii) learning and processing, and (iv) neuroscience. As such it provides a snapshot of the different research strands that have focused on language and music, identifying current trends and methodologies that have been (or could be) applied to the study of both domains, and outlining future research directions. This volume is valuable in promoting the investigation of language and music by fostering interdisciplinary discussion and collaboration. With an ever increasing interest in both music cognition and language, this book will be valuable for students and researchers of psychology, linguistics, neuroscience, and musicology.

This collection brings together linguistic, psychological, and sociological perspectives reflecting on the relationships and interactions of the multilayered factors impacting second language development and cognitive competence. The book advocates a system approach as a counterpoint to existing scholarship, which has tended to focus on a small set of variables. The 13 chapters demonstrate the ways in which cognitive and linguistic development are intrinsically linked, occurring within a nested structure of multiple levels: individual neuro-cognitive systems and processes, individual engagement with the social world, and the wider social and institutional environments and cultural contexts affecting the belief systems and linguistic conventions of social groups. The volume begins by outlining the theoretical and methodological foundations before moving into a more focused look at the interplay of these different variables at the macro, meso, and micro levels. A final section features two commentary chapters from linguistics and psychology, respectively, synthesizing insights from earlier chapters and situating the collection within broader scholarship on linguistic and cognitive development, theoretical and methodological implications, and discussions of avenues for future empirical research. This book will be of particular interest to scholars in second language acquisition, psycholinguistics, cognition, psychology, and sociology.

Leading scholars examine the relationship between child language acquisition and cognitive development.

Direct object omission is a general occurrence, observed in varying degrees across the world's languages. The expression of verbal transitivity in small children begins with the regular use of verbs without their object, even where object omissions are illicit in the ambient language. Grounded in generative grammar and learnability theory, this book presents a comprehensive view of experimental approaches to object acquisition, and is the first to examine how children rely on the lexical, structural and pragmatic components to unravel the system. The results presented lead to the hypothesis that missing objects in child language should not be seen as a deficit but as a continuous process of knowledge integration. The book argues for a new model of how this aspect of grammar is innately represented from birth. Ideal reading for advanced students and researchers in language acquisition and syntactic theory, the book's opening and closing chapters are also suitable for non-specialist readers.
