This important book provides a broad, integrated overview of current research on word-finding deficit, anomia, the most common symptom of language dysfunction occurring after brain damage. Besides its clinical importance, anomia gives a fascinating view on the inner workings of language in the brain. Written by two internationally known researchers in the field, the book begins with an overview of psycholinguistic research on normal word retrieval as well as the influential cognitive models of naming and goes on to review the major forms of anomia. Neuroanatomical aspects, clinical assessment and therapeutic approaches are reviewed and evaluated. This edition has been fully updated to include coverage of advances in cognitive modeling of lexical retrieval disorders, structural and functional neuroimaging findings on the neural basis of naming and anomia, anomia diagnostics and new approaches to the challenging task of anomia therapy. Covering both theory and practice, this book provides invaluable reading for researchers and practitioners in speech and language disorders, neuropsychology and neurology, as well as for advanced undergraduate students and graduate students in the field.
