Linguistic Investigations Of Aphasia

A Linguistic Investigation of Aphasic Chinese Speech is the first detailed linguistic analysis of a large body of aphasic Chinese natural speech data. This work describes how the major aphasia syndromes are manifest in Chinese, a language which differs significantly from languages upon which traditional aphasia theory is based. Following the Chinese data, a new explanation for the major aphasia syndromes is offered based on the cognitive science modularity hypothesis. The theory posits that Broca's aphasia is the result of computational deficits that occur within linguistic components, while Wernicke's aphasia is the result of deficits that occur in the transfer of information between components. It is demonstrated how the fluent and non-fluent characteristics of the major aphasia syndromes follow directly from the properties of cognitive modules. Detailed linguistic descriptions of Broca's and Wernicke's aphasia in Chinese are provided, including a summary of diagnostics of aphasia type. The complete corpora of four aphasic Chinese speakers, including interlinear and free translations, are presented in an Appendix.

A comprehensive introduction to the emerging fields of neurolinguistics and linguistic aphasiology stresses concepts from the contributing disciplines of neurology, linguistics, psychology and speech.

“Non-fluent Aphasia in a Multilingual World” is an up-to-date introduction to the language of patients with non-fluent aphasia. Recent research in languages other than English has challenged our old descriptions of aphasia syndromes: while their patterns can be recognized across languages, the structure of each language has a profound effect on the symptoms of aphasic speech. However, the basic linguistic concepts needed to understand these effects in languages other than English have rarely been part of the training of the clinician. “Non-fluent Aphasia in a Multilingual World” introduces these concepts plainly and concretely, in the context of dozens of examples from the narratives and conversations of patients speaking most of the major languages of Europe, North America and Asia. Linguistic and clinical terms are carefully defined and kept as theory neutral as possible. “Non-Fluent Aphasia in a Multilingual World” is especially useful for speech-language pathologists whose patients are immigrants and guestworkers, and for the clinician who must deal creatively with the challenges of providing aphasia diagnosis and therapy in a multicultural, multidialectical setting.

Linguistic Analyses of Aphasic Language represents results from linguistic and neurolinguistic research on aphasic language performance. The contributions encompass all linguistic levels, ranging from phonetics to discourse, and present results on languages other than English. The findings and applied methods are both relevant to the study of aphasia in general and to cross-linguistic analyses. Furthermore, they have clear implications for language and speech therapy and thus show the importance of linguistic concepts for language testing and therapeutic intervention.

Seminar paper from the year 2001 in the subject American Studies - Linguistics, grade: 1,3, Johannes Gutenberg University Mainz (Seminar für Englische Philologie), course: Bilingualism - Multilingualism, language: English, abstract: Brain diseases and disorders are fields of neurology that have still not been fully examined. Neurologists are constantly facing new mysteries concerning the processes that take place on in the brain. Especially the aspect of language offers a wide spectrum for research, from the medical point of view as well as from the linguistic one. As I will concentrate on the aspect of language, or more precisely the affection of the faculty of language, which means its production and comprehension, the affection aphasia offers a good example. Aphasia is a very complex problem, and it is still not totally examined by scientific researchers and brain specialists. The field of aphasia includes many different kinds of aphasia, different clinical pictures, symptoms, and recovery patterns. At any rate, the patients have difficulties in producing or understanding language, although to different degrees. Aphasia in bilingual and multilingual persons is a field of neurology that deserves further research. It offers new aspects to the research on brain activity, and it offers the opportunity of approaching the problem of aphasia in a new way. Nevertheless, there are different, one word even contradicting theories from specialists all over the world concerning the impact of aphasia on speakers of more than one language and the reasons for it, some of which will be presented in this research paper. As this research paper is written in order to take a closer look at the problems with language in aphasia, it is inevitable to present some medical facts and theories in order to explain the impact of aphasia on the production, understanding and recovery of language. I will start with an introduction to the physical structure of the brain, especially on the areas that are associated with language. Further on, a definition of aphasia, its causes, and a description of the different types of aphasia and their specific symptoms will be given. As the process of recovery is extremely interesting and the observation of it important because it allows us to draw conclusions on how the brain works, a section of the research paper will be devoted to this point. Moreover, the case studies of bilingual and multilingual aphasic patients offer interesting aspects for linguistic and medical research because of the possibility of understanding how language is stored in the brain, and whether different languages are stored in different parts of the brain, perhaps even in the other hemisphere.

Investigations in Clinical Phonetics and Linguistics is a sequel to the eighth meeting of the International Clinical Phonetics and Linguistics Association, attended by delegates from 26 different countries. This book reflects the scope of the subject area of clinical phonetics and linguistics, the balance of input into it with respect to the different kinds of research being carried on, and the representation of researchers from different parts of the world. Its scope includes the application of all levels of linguistic analysis and the chapters of the book have been ordered as far as possible according to linguistic level, beginning with pragmatics and ending with acoustics. It will be immediately apparent that a greater number of chapters are concerned with applications of phonetics and phonology then with any other levels.
