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.

Studies in Neurolinguistics, Volume 3 presents detailed case histories, multi-subject experimental studies, literature reviews, and research papers that employ a variety of experimental and observational techniques. This volume contains seven chapters that focus on a wide range of research in the field of neurolinguistics. Chapter 1 discusses the various approaches to the problem of auditory comprehension in aphasia. A survey of the world's literature on bilingualism and aphasia is provided in chapter 2. The third chapter examines the different models and explanations for conduction aphasia. Chapter 4 provides a synthesis of the anatomic, physiologic, and behavioral research on the role of the limbic system in human communication. Chapter 5 presents a model of individual differences in hemispheric functioning, in which a number of theories about the left and right hemispheres are analyzed and compared. Chapter 6 shows how different levels of language are revealed. The last chapter addresses "The Question of Electrophysiological Asymmetries Preceding Speech" in a study of the readiness potentials over the motor and premotor regions in eight subjects. Linguists, psychologists, and neurologists will find the book highly informative.

Linguistics and Aphasia is a major study of recent developments in applying psycholinguistics and pragmatics to the study of acquired language disorders (aphasia) and their remediation. Psycholinguistic analyses of aphasia interpret disorders in terms of damaged modules and processes within what was once a normal language system. These analyses have progressed to the point that they now routinely provide a model-based rationalefor planning patient therapy. Through a series of case studies, the authors show how the psycholinguistic analysis of aphasia can be assessed for its effectiveness in clinical practice. Pragmatic approaches to the study of aphasia are of more recent origin. Ruth Lesser and Lesley Milroy evaluate their considerable significance to the study of aphasia and their relevance to practical issues of diagnosis and treatment. Controversial analysis, in particular, offers a fruitful and productive framework within which to assess the functional adequacy of the language used by aphasic speakers in everyday contexts.
