The author states that this monograph was prepared for advanced courses in audiology, language pathology, special education, and psychology. Especially fascinating is the first section on the nature and extent of deafness, treated from the psychological point of view. This section includes an excellent chapter on the effect of sensory deprivation on behavior. Most of this book deals with experimental evidence on the psychology of deafness, much of it statistically treated. This includes studies on deafness and mental development, motor functioning, personality, language, and the relation of these factors to other handicaps. This book will serve as an excellent authoritative reference work in its special field.
