The editors of this important volume have pioneered the kinds of thoughtful studies basic to understanding, diagnosing, and treating auditory processing disorders. In this handbook, they have assembled a truly impressive stable of national and international contributors to virtually every aspect of the problem. They bring us up to date on the latest findings from the standpoint of behavioral assessment, electrophysiologic measures, and the neurobiology of the disorder, all relevant to the identification and diagnosis of this troubling malady. -- From the Foreword, by James Jerger, Ph.D. The first volume of Musiek and Chermak's definitive handbook provides comprehensive coverage of auditory neuroscience and clinical science needed to accurately diagnose the range of developmental and acquired (C)APD disorders in children, adults, and older adults. With contributions from world-renowned authors, the handbook reflects major advances in auditory neuroscience and cognitive science, particularly over the last two decades. The chapters in this volume cover basic science foundations, diagnostic principles and procedures, and multidisciplinary assessment, as well as addressing the ongoing research and development in diagnostics.
