This volume presents a broad overview of current research and thought on aphasia in individuals who speak more than one language. The range of topics covered, and their in-depth treatment, should be of interest to researchers, clinicians, and students.

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.

The Bilingual Aphasia Test is a comprehensive language test designed to assess the differential loss or sparing of various language functions in previously bilingual individuals. The individual is tested, separately, in each language he or she previously used, and then in the two languages simultaneously. The testing is multimodal -- sampling hearing, speaking, reading, and writing; and multidimensional -- testing various linguistic levels (phonological, morphological, syntactic, lexical, and semantic), tasks (comprehension, repetition, judgment, lexical access and propositionizing), and units (words, sentences, and paragraphs). The BAT is structured as follows: * To test a bilingual aphasic, you will need the following testing elements: the stimulus books for each of the languages in which the individual was formerly fluent, the single-language tests for each of these languages, as well as the bilingual test that links them. For example, if you are testing an English-French bilingual aphasic, you will need an English stimulus book, a French stimulus book, an English single-language test, a French single-language test, and an English-French bilingual test. * The BAT can also be used to test monolingual aphasics. To test for monolingual aphasia, you will need the stimulus book and the single-language test in the language in which the individual was formerly fluent. * Professor Paradis' book, The Assessment of Bilingual Aphasia, provides the background material and serves as the manual for the test. The BAT is available in dozens of languages and language pairs. There are now 106 bilingual pairs available. Additional single-language and bilingual tests are being prepared continuously. If the language (or language pair) you need is not listed, please call LEA to find out if and when it will be available.

Seminar paper from the year 2007 in the subject English Language and Literature Studies - Linguistics, grade: 1.0, Justus-Liebig-University Giessen, language: English, abstract: At present, approximately two thirds of the world's population is bilingual. Globalisation, migration and decreasing gaps between different cultures and countries make the ability to speak two or more languages necessary, and, consequently, the number of bilingual people increases steadily. The ever-increasing, significant number of people speaking two or more languages has caused high interest, among psychologists, educators and also psycholinguists, in the cognitive and cerebral study of the bilingual. An important part of the research is the study of bilingual aphasia, meaning the loss of the capability to comprehend and/or speak a language, either totally or in part, which is a result of brain injuries often caused by diseases, such as strokes or tumours, war injuries or car accidents (cf. Myers-Scotton 2006: 317). Studying bilingual aphasia and its impacts on the bilingual's different languages contributes to finding an answer to the question of how two or more languages are organised and represented in the brain. In so doing, this field of research posits hypotheses concerning the cerebral organisation of language in general and the parts of the brain which function for its production. After having defined the terms bilingualism and bilingual, which is a necessary prerequisite to avoid confusing ambiguities in the following text, this essay will illustrate the most common patterns of language recovery and their relative incidence. This illustration will be followed by an overview of early suggested and attempted explanations for the questions about which brain mechanisms are responsible for the various patterns, why a certain patient shows a certain recovery pattern and why one language in some cases remains more intact than the other, or why sometimes one is preserved, while the oth
