This book "asserts that the origin and spread of languages must be examined primarily through the time-tested techniques of linguistic analysis, rather than those of evolutionary biology" and "defends traditional practices in historical linguistics while remaining open to new techniques, including computational methods" and "will appeal to readers interested in world history and world geography."
Current approaches to treating stuttering do not reflect the new understanding of its nature which has emerged from recent studies. This book brings together speech scientists and clinicians to discuss the best ways to close the perceived gap and maximize the effectiveness of treatment. Together, the chapters offer a comprehensive state-of-the-art overview of the complexities of stuttering and its remediation. Genetic, neuropsychological, behavioral, and often-neglected affective and cognitive factors are all considered. Preferred methodologies for empirical investigation are described, and specific examples of applied clinical research designs are provided. The book will be crucial reading for all those professionally concerned with fluency disorders and their students.
