Agrammatic aphasia (agrammatism), resulting from brain damage to regions of the brain involved in language processing, affects grammatical aspects of language. Therefore, research examining language breakdown (and recovery) patterns in agrammatism is of great interest and importance to linguists, neurolinguists, neuropsychologists, neurologists, psycholinguists and speech and language pathologists from all over the world. Research in agrammatism, studied across languages and from different perspectives, provides information about the grammatical structures that are affected by brain damage, their nature, and how language (and the brain) recovers from brain damage. The chapters in this book focus on the symptoms that arise in agrammatic aphasia at the lexical, morphological and sentence level and address these impairments from neurolinguistic, neuropsychological and neurological perspectives. Special attention is given to methods for assessment and treatment of agrammatism and to the neurobiological changes that can result from the treatments. Perspectives on Agrammatism provides an up-to-date overview of research that has been done over the past two decades. With contributions from the most influential aphasiologists from Europe and the United States, it provides an indispensable reference for students and academics in the field of language disorders.

Contemporary and Emergent Theories of Agrammatism provides an in-depth review of the previous five decades of research on agrammatism focusing specifically on work which has been informed by linguistic theory. The final chapters reflect the recent turning point in the conceptualization of the underlying causes of the impairments agrammatic individuals present with. The book includes chapters on impairments to grammatical morphemes the tree pruning and trace deletion hypotheses verb deficits in sentences, and as single words generalized minimality adaptation theory and slow syntax the involvement of discourse To facilitate student reading the writing is clear and accessible, and the book includes a glossary of unfamiliar terms. Contemporary and Emergent Theories of Agrammatism will be of great interest to advanced students and researchers in areas such as psychology of language, linguistics, neurolinguistics, aphasiology and speech and language therapy.

Agrammatism provides an overview of the state of knowledge on agrammatism, typically defined as a disorder of sentence production involving the selective omission of function words and some grammatical endings on words. The book opens with discussions of the diversity of the disorder. This is followed by separate chapters that address primarily questions of syntactic structure in agrammatism, from both linguistic and psycholinguistic perspectives. Within these two gross sections there is no consensus among the conclusions reached by the various authors. However, the position is taken that agrammatism is a disorder distinct from other aphasie disorders of sentence structure. This position is reconsidered in the final two chapters. Because of the intrinsically interdisciplinary character of research on agrammatism, it is hoped that the work presented in this volume will be of interest to linguists and psycholinguists working in areas outside the domain of aphasia, as well as to neurolinguists and neuropsychologists who are already involved in the study of language deficits.

This critical history of research on acquired language deficits (aphasias) demonstrates the usefulness of linguistic analysis of aphasic syndrome for neuropsychology, linguistics, and psycholinguistics. Drawing on new empirical studies, Grodzinsky concludes that the use of grammatical tools for the description of the aphasias is critical. The selective nature of these deficits offers a novel view into the inner workings of our language faculty and the mechanisms that support it.In contrast to other proposals that the left anterior cerebral cortex is crucial for all syntactic capacity, Grodzinsky's discoveries support his theory that this region is necessary for only a small component of the human language faculty. On this basis he provides a detailed explanation for many aphasic phenomena - including a number of puzzling cross-linguistic aphasia differences - and uses aphasic data to evaluate competing linguistic theories.Yosef Grodzinsky is a member of the psychology faculty at Tel Aviv University. "Theoretical Perspectives on Language Deficits" is included in the series Biology of Language and Cognition, edited by John P. Marshall. A Bradford Book.

This book brings together experts from the fields of linguistics, psychology and neuroscience to explore how a multidisciplinary approach can impact on research into the neurocognition of language. International contributors present cutting-edge research from cognitive and developmental psychology, neuropsychology, psycholinguistics and computer science, and discuss how this contributes to neuropsycholinguistics, a term coined by Jean-Luc Nespoulous, to whom this book is dedicated. Chapters illustrate how researchers with different methods and theoretical backgrounds can contribute to a unified vision of the study of language cognition. Reinterpreting neuropsycholinguistics through the lens of each research field, the book demonstrates important attempts to adopt a comprehensive view of speech and language pathology. Divided into three sections the book covers: linguistic mechanisms and the architecture of language the relationship between language and other cognitive processes the assessment of speech and language disabilities and compensatory mechanisms. Neuropsycholinguistic Perspectives on Language Cognition presents a unique contribution to cognitive science and language science, from linguistics to neuroscience. It will interest academics and scholars in the field, as well as medical researchers, psychologists, and speech and language therapists.

Essay from the year 2015 in the subject English Language and Literature Studies - Linguistics, grade: 2,0, University College Dublin, course: Seminar: Language Impairment, language: English, abstract: In this Essay the Trace Deletion Hypothesis by Grodzinsky as well as the Tree Pruning Hypothesis by Friedmann and Grodzinsky will be explained, the first of which focuses on the impaired comprehension while the latter concerns itself with the impaired production in agrammatism. A result of Broca's aphasia, agrammatism is a disorder which involves a lack of grammaticality in language production and a reduced understanding of grammatical markers. Agrammatic patients speak in telegraphic style, often omitting grammatical morphemes and function words while content words can still be used accurately. Language comprehension is also limited to content words whereas grammatical markers are not processed. This disorder hence affects both production and comprehension, which is why linguistic theories concerning agramatism differ in focus.
