The Neurolinguistics of Bilingualism

This book introduces the reader to both neurolinguistics per se and the neuropsychological aspects of bilingualism. Neurolinguistics may roughly be defined as a subset of neuropsychology, namely the study of the representation and processing of language in the brain. To this effect, the first chapters of the book focus on the basic neuropsychology of language processing and acquisition. The second half of the book addresses the issues of cerebral representation and processing of language in bi-or multilingual subjects. All aspects are systematically dealt with, namely the definition of bilingualism; an analysis of all the issues related to bilingual aphasia, i.e. patterns of recovery of the patients' carious languages in diverse population; an investigation of the methodologies used in the study of the neuropsychological aspects of the various linguistic functions, such as comprehension, production and translation; and lastly, the issues of cerebral lateralization and neuroanatomical localization of the numerous cortical and subcortical structures subserving the various language system components in multilingual subjects. It is an excellent introduction to both the neuropsychology of language and the phenomena related to bilingualism. This book will be of particular interest to students of language therapy, aphasiology, applied psycholinguistics, neurolinguistics and, in general, to students of medicine who wish to become more knowledgeable about the specific needs of patients in a multilingual society.
