Spoken Word Production And Its Breakdown In Aphasia

This volume combines in-depth reviews of models of spoken word production and cognitive neuropsychological disorders of spoken word production. The first section provides a detailed discussion of the development and structure of current models of language production using data form "normal" subjects. It is these models that form the basis of the study and therefore the text attempts to explain their processing mechanisms and assumptions clearly. The evidence used for the development of these models is described including experimental studies and observation of patterns in naturally occurring speech errors.; The second section focuses on studies of aphasic naming disorders and discusses these disorders in terms of the model described in the first section. The emphasis is on single case studies. These are reviewed in three chapters examining semantic errors and disorders, the range of symptoms attributed to disorders of lexical retriveal and deficits of phonological encoding. The text assumes that the reader has some familiarity with the linguistic and psychological terminology relevant to these areas and therefore is most suited to the graduate student or researcher/lecturer.

This volume focuses on the remediation of impairments of word production in aphasia. It is restricted to studies focusing on single word production and comprises papers by some of the researchers most active in this field worldwide. The scope of the papers is broad and includes many relatively under-researched areas and techniques. All the papers have in common a methodological rigour and the use of a single case or case-series approach. A range of treatment tasks are evaluated: 'phonological' tasks such as phonological cueing and word repetition, and judgements regarding the phonological form; 'orthographic' tasks such as orthographic cueing, word reading and writing to dictation; 'semantic' tasks such as semantic cueing; the use of gesture; computer presentation of tasks and even just repeated attempts at naming. In addition, the individuals treated using these techniques varied in the nature of their impairments and/or level of impairment that was targeted. The majority aimed to improve word retrieval generally, but one treatment was aimed specifically at verb retrieval, and another at improving accuracy of word production for an individual with a phonological encoding impairment. Each paper relates the outcome of treatment to theoretical accounts of impairment, and one explicitly uses the results of therapy to inform these theories. Taken together these papers provide a snapshot of the 'state of the art' in the rehabilitation of word production in aphasia.

The papers in this volume all examine the nature of spoken word production in aphasia, and how this can inform current theories of language processing. It comprises 7 papers by some of the foremost researchers in the field. The first paper in the volume is an introduction by the editor (Dr Lyndsey Nickels), which reviews the 'state of the art' of the cognitive neuropsychology of spoken word production both in terms of theory and methodology. The individual papers address a range of topical issues including the levels of processing in speech production (Lambon-Ralph, Moriarty, Sage et al.; Wilshire); the nature of the interaction between levels of processing (Goldrick & Rapp);and effects of different factors on naming (word class and context: Berndt, Burton, Haendiges & Mitchum; phonemic and orthographic cues: Best, Herbert, Hickin, Osborne & Howard); lexical stress: Howard & Smith). Taken together this volume provides the reader with an insight into the cutting edge of research in spoken word production.

This volume represents major research issues in language production today, presenting readers with a picture of the breadth of current research in the field. Contributors have focused on models of visual word processing, aphasic speech, object recognition and language production in children. Many chapters highlight the need for psychological models of language production to learn from theoretical linguistics in order to become better informed about the structure of language itself. Therefore, this volume also includes chapters written by linguists for psychologists which serve to remind us of the complexity of structure and process in the languages of the world.

This volume comprises contributions from different disciplines (cognitive psychology, linguistics, computer science, neuroscience) concerned with the generation of natural speech. It summarizes the outcome of a six-year long priority program funded by the German Research Foundation (DFG) that aimed at bringing together colleagues with different viewpoints but sharing a principal interest in the cognitive processes underlying language production. The result is a state-of-the-art discussion of one of the most fascinating branches of human behavior taking into account a particularly rich multidisciplinary empirical data base.

The domain of Communication Disorders has grown exponentially in the last two decades and has come to encompass much more than audiology, speech impediments and early language impairment. The realization that most developmental and learning disorders are language-based or language-related has brought insights from theoretical and empirical linguistics and its clinical applications to the forefront of Communication Disorders science. The current handbook takes an integrated psycholinguistic, neurolinguistic, and sociolinguistic perspective on Communication Disorders by targeting the interface between language and cognition as the context for understanding disrupted abilities and behaviors and providing solutions for treatment and therapy. Researchers and practitioners will be able to find in this handbook state-of-the-art information on typical and atypical development of language and communication (dis)abilities across the human lifespan from infancy to the aging brain, covering all major clinical disorders and conditions in various social and communicative contexts, such as spoken and written language and discourse, literacy issues, bilingualism, and socio-economic status.

Bringing together a range of experts, the editors of this volume aim to show how psycholinguistic models of normal speech processing can be applied to the study of disorders of speech production, such as stuttering, aphasia and verbal dyspraxia.
