Introduces students to the scientific study of language, using the basic principles of complexity theory.

How do children learn their first words? The field of language development has been polarized by responses to this question. Explanations range from accounts that emphasize the importance of cognitive heuristics in language acquisition, to those that highlight the role of "dumb attentional mechanisms" in word learning. This monograph offers an alternative to these accounts. A hybrid view of word-learning, called the emergentist coalition theory, combines cognitive constraints, social-pragmatic factors, and global attentional mechanisms to arrive at a balanced account of how children construct principles of word learning. In twelve experiments, with children ranging from 12 to 25 months of age, data are described that support the emergentist coalition theory.

The remarkable way in which young children acquire language has long fascinated linguists and developmental psychologists alike. Language is a skill that we have essentially mastered by the age of three, and with incredible ease and speed, despite the complexity of the task. This accessible textbook introduces the field of child language acquisition, exploring language development from birth. Setting out the key theoretical debates, it considers questions such as what characteristics of the human mind make it possible to acquire language; how far acquisition is biologically programmed and how far it is influenced by our environment; what makes second language learning (in adulthood) different from first language acquisition; and whether the specific stages in language development are universal across languages. Clear and comprehensive, it is set to become a key text for all courses in child language acquisition, within linguistics, developmental psychology and cognitive science.

The origins of learner corpus research go back to the late 1980s when large electronic collections of written or spoken data started to be collected from foreign/second language learners, with a view to advancing our understanding of the mechanisms of second language acquisition and developing tailor-made pedagogical tools. Engaging with the interdisciplinary nature of this fast-growing field, The Cambridge Handbook of Learner Corpus Research explores the diverse and extensive applications of learner corpora, with 27 chapters written by internationally renowned experts. This comprehensive work is a vital resource for students, teachers and researchers, offering fresh perspectives and a unique overview of the field. With representative studies in each chapter which provide an essential guide on how to conduct learner corpus research in a wide range of areas, this work is a cutting-edge account of learner corpus collection, annotation, methodology, theory, analysis and applications.

Measuring Second Language Vocabulary Acquisition provides an examination of the background to testing vocabulary knowledge in a second language and in particular considers the effect that word frequency and lexical coverage have on learning and communication in a foreign language. It examines the tools we have for assessing the various facets of vocabulary knowledge such as aural and written word recognition, the link with word meaning, and vocabulary depth. These are illustrated and the scores they produce are demonstrated to provide normative data. Vocabulary acquisition from course books and in the classroom in examined, as is vocabulary uptake from informal tasks. This book ties scores on tests of vocabulary breadth to performance on standard foreign language examinations and on hierarchies of communicative performance such as the CEFR.

This book investigates various aspects of speaking in a foreign language. It is unique in considering this key skill from both psycholinguistic and sociolinguistic perspectives, and in focusing entirely on instructed foreign language contexts. The book demonstrates how theory and research can be translated into classroom practice.
