'Fascinating. . . This engaging book explores just how multiple languages are acquired and sorted out by the brain. . . Costa's work derives from a great fund of knowledge, considerable curiosity and solidly scientific spirit' Philip Hensher Spectator The definitive study of bilingualism and the human brain from a leading neuropsychologist Over half of the world's population is bilingual and yet few of us understand how this extraordinary, complex ability really works. How do two languages co-exist in the same brain? What are the advantages and challenges of being bilingual? How do we learn - and forget - a language? In the first study of its kind, leading expert Albert Costa shares twenty years of experience to explore the science of language. Looking at studies and examples from Canada to France to South Korea, The Bilingual Brain investigates the significant impact of bilingualism on daily life from infancy to old age. It reveals, among other things, how babies differentiate between two languages just hours after birth, how accent affects the way in which we perceive others and even why bilinguals are better at conflict resolution. Drawing on cutting-edge neuro-linguistic research from his own laboratory in Barcelona as well from centres across the world, and his own bilingual family, Costa offers an absorbing examination of the intricacies and impact of an extraordinary skill. Highly engaging and hugely informative,The Bilingual Brain leaves us all with a sense of wonder at how language works. Translated by John W. Schwieter

Arturo Hernandez presents the results of 25 years of research into the factors that might help us to understand how two (or more) languages are stored in one brain. It is clear that the brain is not egalitarian—some languages are privileged and others are not, but why?

Cases of language loss and recovery bring up an intriguing paradox. If two languages are stored in the brain, how can it be that a person can lose one of them, but not the other, and then gain one back without relearning it? The traditional models of how a language is represented in the brain suggest that languages can become inaccessible, even though they are not entirely lost. As the author demonstrates through fascinating cases, stress--whether due to foreign language immersion, sleep deprivation, or brain damage--can lead to the apparent loss of one language, but not the other. Arturo Hernandez presents the results of 25 years of research into the factors that might help us to understand how two (or more) languages are stored in one brain. It is clear that the brain is not egalitarian--some languages are privileged and others are not, but why? Hernandez will extend recent work that has begun to take a biological or natural systems approach. He proposes that, in bilinguals, two languages live inside a brain almost like two species live in an ecosystem. For the most part they peacefully co-exist and often share resources. But they also compete for resources, particularly when under stress. Although there are still many questions to answer and many puzzles to solve, Hernandez argues that the nonlinear dynamical models, which have been used to uncover the underlying mechanisms seen in natural systems and more recently in language and cognition, can be used to shed considerable light on the neural bases of bilingualism.

Foundations of Bilingual Memory provides a valuable update to the field of bilingual memory and offers a new psychological perspective on how the bilingual mind encodes, stores, and retrieves information. This volume emphasizes theoretical issues, such as classic memory approaches, Compound-Coordinate Bilingualism, Bilingual Dual Coding Theory, and Working Memory, about which relatively little has been written in the bilingual domain. Also covered are: • The neuropsychology of bilingual memory • Applied issues (such as false memories and bilingualism, emotion and memory) • Empirical findings in support of the uniqueness of the different memory systems of the bilingual individual • Connectionist models of bilingualism The volume represents the first book of its kind, in stressing a memory perspective with regards to bilingual speakers. It can serve as an advanced text for both undergraduate and graduate level students and it will be of great interest to the growing number of bilingual teachers and university classes interested in understanding the bilingual mind, as well as in preparing teachers to work with the bilingual individual.

This thought-provoking monograph makes a multidisciplinary case for bilingualism as a possible enhancer of executive function, particularly cognitive control. Its central focus is the cognitive operations of the bilingual brain in processing two languages and whether they afford the brain a greater edge on neuroplasticity—in short, a cognitive advantage. Major issues and controversies in the debate are analyzed from cognitive neuroscience, psycholinguistic, and integrative perspectives, with attention paid to commonly and rarely studied domains at work in bilingual processing. The author also pinpoints future areas for improved research such as recognizing the diversity of bilingualism, not simply in languages spoken but also in social context, as seen among immigrants and refugees. Included in the coverage: The evolution of bilingualism. What goes on in a bilingual mind? The core cognitive mechanisms. Cognitive advantage of bilingualism and its criticisms. Neuroscience of bilingualism. Bilingualism, context, and control. Attention, vision, and control in bilinguals. With its cogent takes on ongoing questions and emerging issues, Bilingualism and Cognitive Control is of immediate interest to bilingual researchers and practitioners interested in understanding the behavioral aspects and neurobiology of bilingualism and the dynamic character of the bilingual/multilingual/second language learner’s mind, as well as the growing number of advanced undergraduate and graduate students interested in the psychology/psycholinguistics of bilingualism, bilingual cognitive psychology, cognitive science, and cognitive neuroscience.

This book fills a critical gap in the cross-cultural literature by illuminating the bilingual experience in both its social and clinical contexts. Rafael Javier makes a convincing, empirically founded case for what he terms the bilingual mind, with its own particular approach to cognition, memory, and emotional and social development. Using this framework, he provides answers to important questions about the way bilingualism affects cognition and development.
