In recent years, linguists have increasingly turned to the cognitive sciences to broaden their investigation into the roots and development of language. With the advent of cognitive-linguistic, usage-based and complex-adaptive models of language, linguists today are utilizing approaches and insights from cognitive psychology, neuropsychology, social psychology and other related fields. A key result of this interdisciplinary approach is the concept of entrenchment—the ongoing reorganization and adaptation of communicative knowledge. Entrenchment posits that our linguistic knowledge is continuously refreshed and reorganized under the influence of social interactions. It is part of a larger, ongoing process of lifelong cognitive reorganization whose course and quality is conditioned by exposure to and use of language, and by the application of cognitive abilities and processes to language. This volume enlists more than two dozen experts in the fields of linguistics, psycholinguistics, neurology, and cognitive psychology in providing a realistic picture of the psychological and linguistic foundations of language. Contributors examine the psychological foundations of linguistic entrenchment processes, and the role of entrenchment in first-language acquisition, second language learning, and language attrition. Critical views of entrenchment and some of its premises and implications are discussed from the perspective of dynamic complexity theory and radical embodied cognitive science.

This volume outlines a model of language that can be characterized as functionalist, usage-based, dynamic, and complex-adaptive. The core idea is that linguistic structure is not stable and uniform, but continually refreshed by the interaction between three components: usage, the communicative activities of speakers; conventionalization, the social processes triggered by these activities and feeding back into them; and entrenchment, the individual cognitive processes that are also linked to these activities in a feedback loop. Hans-Jörg Schmid explains how this multiple feedback system works by extending his Entrenchment-and-Conventionalization Model, showing how the linguistic system is created, sustained, and continually adapted by the ongoing interaction between usage, conventionalization, and entrenchment. Fulfilling the promise of usage-based accounts, the model explains how exactly usage is transformed into collective and individual grammar and how these two grammars in turn feed back into usage. The book is exceptionally broad in scope, with insights from a wide range of linguistic subdisciplines. It provides a coherent account of the role of multiple factors that influence language structure, variation, and change, including frequency, economy, identity, multilingualism, and language contact.

This volume is the first handbook dedicated to language attrition, the study of how a speaker's language may be affected by crosslinguistic interference and non-use. Topics covered include theoretical implications, psycho- and neurolinguistic approaches, linguistic and extralinguistic factors, L2 attrition, and heritage languages.

This book puts cognition back at the heart of the language learning process and challenges the idea that language acquisition can be meaningfully understood as a purely linguistic phenomenon. For each domain placed under the spotlight - memory, attention, inhibition, categorisation, analogy and social cognition - the book examines how they shape the development of sounds, words and grammar. The unfolding cognitive and social world of the child interacts with, constrains, and predicts language use at its deepest levels. The conclusion is that language is special, not because it is an encapsulated module separate from the rest of cognition, but because of the forms it can take rather than the parts it is made of, and because it could be nature’s finest example of cognitive recycling and reuse.

Experts from psycholinguistics and English historical linguistics address core factors in language change.

Re-examines frequency, entrenchment and salience, three foundational concepts in usage-based linguistics, through the prism of learning, memory, and attention.

The study of “usage” has constituted a major line of second language learning research for decades now. The concept of usage, however, can be defined and studied in many different ways. In this comprehensive, forward-looking text, international scholars from a variety of perspectives review and critically examine current conceptualizations of usage, learning, and their connections in the field of second language acquisition (SLA). Bringing these diverse perspectives into conversation, Kevin McManus synthesizes the state of the art to set the agenda for new directions in theory-building and empirical SLA research. This text will be an invaluable resource to students and researchers in SLA, applied linguistics, psychology and cognitive science, education, and related areas.
