Although DLDs are common, we are still a long way from understanding what causes them and how best to intervene. Understanding Developmental Language Disorders summarises the recent research developments in genetics and neuroimaging studies, assessment techniques and treatment studies to provide an overview of all aspects of DLD. The book investigates the possible genetic and biological causes of the disorder, how best to assess children's language skills to identify when and where communication breakdown occurs, what the long-term outcomes are for children who grow up with DLD, overlaps between DLD and other childhood disorders such as dyslexia and autism and how best to treat children with the disorder. Each chapter is written by a leading authority in the field in a format accessible to researchers, clinicians and families alike.
This book, with its focus on both theory and practice, will be invaluable to students and researchers of speech-language pathology, psychology, psychiatry, linguistics and education. It will also be of interest to practicing speech-language pathologists, clinical psychologists, psychiatrists, educational psychologists, and teachers and parents of children with developmental language disorders.
Part I explains fluency in reading from both traditional and modern perspectives. Fluency has historically been viewed as the outcome of other reading-related factors and has often been seen as a convenient measure of reading skills. This book, however, argues that fluency has a strong impact on other aspects of reading and plays a central role in the entire reading process.
Part II deals with the determinants of reading fluency. Chief among these is the speed of information processing in the brain. Using both behavioral and electrophysiological evidence, the book systematically examines the features of processing speed in the various brain systems involved in reading: visual-orthographic, auditory-phonological, and semantic and shows how speed of processing affects fluency in reading.
Part III deals with the complex issues of cross-modal integration and specifically with the need for effective synchronization of the brain processes involved in reading. It puts forward the Synchronization Hypothesis and discusses the role of the Asynchrony Phenomenon as a major factor in dyslexia. Finally, it summarizes research on manipulating reading rate by means of the Acceleration method, providing evidence for a possible intervention aimed at reducing Asynchrony.
Key features of this outstanding new book include:
*Expanded View of Fluency. Reading fluency is seen as both a dependent and an independent Variable. Currently available books focus on reading rate solely as the outcome of other factors whereas this volume stresses that it is both an outcome and a cause.
*Information Processing Focus. Fluency itself is determined to a large extent by a more general factor, namely, speed of processing in the brain. The book presents wide-ranging evidence for individual differences in speed of processing across many subpopulations.
*Brain Synchronization Focus. The book posits a new theory arguing that effective reading requires synchronization of the different brain systems: visual orthographic, auditory-phonological, and semantic.
*Research-Based Interventions. Interventions to enhance fluency and, thereby, reading skills in general are presented in detail.
*Author Expertise. Zvia Breznitz is Head of the Department of Learning Disabilities and Director of the Laboratory for Neurocognitive Research at Haifa University in Israel, where she has been researching this topic for over a decade.
This book is appropriate for researchers and advanced students in reading, dyslexia, learning disabilities, cognitive psychology, and neuropsychology.
New to This Edition
*Covers additional disorders: intellectual disability, mathematics disorder, and developmental coordination disorder, plus a chapter on less well-validated disorders.
*New case illustrations and a focus on empirically based practice.
*Now grounded in a multiple cognitive-deficit model of learning disorders, replacing the prior edition's modular, single-deficit model.
*An illuminating chapter on controversial therapies separates myths from facts.
Starting with the basics of clinical child neuropsychology and functional anatomy, the authors present a transactional framework for assessment, diagnosis, and intervention. The book carefully links structure and function—and behavioral and biological science—for a more nuanced understanding of brain development and of pathologies as varied as pervasive developmental disorders, learning disabilities, neuromotor dysfunction, seizure disorders, and childhood cancers.
This volume features a range of salient features valuable to students as well as novice and seasoned practitioners alike, including:
Overview chapters that discuss the effects of biogenic and environmental factors on neurological functioning.
New emphasis on multicultural/cross-cultural aspects of neuropsychology and assessment.
Brand new chapters on interpretation, neuropsychological assessment process, and report writing.
An integrative model of neurological, neuroradiological, and psychological assessment and diagnosis.
Balanced coverage of behavioral, pharmacological, and educational approaches to treatment.
Case studies illustrating typical and distinctive presentations and successful diagnosis, treatment planning, and intervention.
Important practice updates, including the new HIPAA regulations.
Child Neuropsychology, 2nd Edition, is vital reading for school, clinical child, and counseling psychologists as well as neuropsychologists. The book also provides rich background and practical material for graduate students entering these fields.
