This book overviews auditory development in nonhuman species and proposes a common time frame for human and nonhuman auditory development. It attempts to explain the mechanisms accounting for age-related change in several domains of auditory processing.
The small but growing body of information about auditory processes in infancy is a tribute to the ingenuity and persistence of investigators in this realm. Undeter red by the frequent expressions of boredom, rage, and indifference in their subjects, these investigators nevertheless continue to seek answers to the intrigu ing but difficult questions about the course of auditory development. In the spring of 1981, a group of leading scholars and researchers in audi tion gathered to discuss the topic, Auditory Development in Infancy, at the 11th annual psychology symposium at Erindale College, University of Toronto. They came from both sides of the Atlantic and from various disciplines, including audiology, neurology, physics, and psychology. They shared their views on theory and data, as well as their perspectives from the laboratory and clinic. One unexpected bonus was an unusually distinguished audience of researchers and clinicians who contributed to lively discussion within and beyond the formal sessions.
The aim of this book is both to reflect current knowledge of perceptual development and to point to some of the many questions that remain unanswered. The study of perceptual development is now a sophisticated science. The majority of the chapters tell a fascinating detective story: the way in which infants perceive and understand the world as they develop. Each of the major sections is prefaced by introductory comments, and the book will be useful for advanced undergraduates, postgraduates, researchers, and other professionals who have an interest in early perceptual development and in infancy in general.
Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.
Development of Auditory and Vestibular Systems fourth edition presents a global and synthetic view of the main aspects of the development of the stato-acoustic system. Unique to this volume is the joint discussion of two sensory systems that, although close at the embryological stage, present divergences during development and later reveal conspicuous functional differences at the adult stage. This work covers the development of auditory receptors up to the central auditory system from several animal models, including humans. Coverage of the vestibular system, spanning amphibians to effects of altered gravity during development in different species, offers examples of the diversity and complexity of life at all levels, from genes through anatomical form and function to, ultimately, behavior. The new edition of Development of Auditory and Vestibular Systems will continue to be an indispensable resource for beginning scientists in this area and experienced researchers alike. - Full-color figures illustrate the development of the stato-acoustic system pathway - Covers a broad range of species, from drosophila to humans, demonstrating the diversity of morphological development despite similarities in molecular processes involved at the cellular level - Discusses a variety of approaches, from genetic-molecular biology to psychophysics, enabling the investigation of ontogenesis and functional development
This multidisciplinary volume features many of the world's leading experts of infant development, who synthesize their research on infant learning and behaviour, while integrating perspectives across neuroscience, socio-cultural context, and policy. It offers an unparalleled overview of infant development across foundational areas such as prenatal development, brain development, epigenetics, physical growth, nutrition, cognition, language, attachment, and risk. The chapters present theoretical and empirical depth and rigor across specific domains of development, while highlighting reciprocal connections among brain, behavior, and social-cultural context. The handbook simultaneously educates, enriches, and encourages. It educates through detailed reviews of innovative methods and empirical foundations and enriches by considering the contexts of brain, culture, and policy. This cutting-edge volume establishes an agenda for future research and policy, and highlights research findings and application for advanced students, researchers, practitioners, and policy-makers with interests in understanding and promoting infant development.
Development of the brain and the emergence of the mind constitute some of the most important concerns of contemporary biology. Disturbances during fetal life may have profound implications for a child's future neurological and psychological development, which can in turn impact society. The new edition of this highly respected work presents a comprehensive review of the basic mechanisms of brain development and the pathophysiology of disorders of the infant brain, written by a team of distinguished neuroscientists, neonatologists, and neuropediatricians. The book follows the main milestones of brain development, from formation of the neural tube and wiring of the neurons in the brain. Neurotrophic factors, neurotransmitters, glial cell biology, cerebral circulation development of sensory functions are all described in detail. Furthermore, there are more philosophical chapters on the evolution of the brain and the emergence of consciousness. Clinical considerations are highlighted where relevant.
