Articulation and Phonological Disorders, Fifth Edition, presents a comprehensive review of information important to the study of clinical phonology. Clearly the most comprehensive book on clinical phonology, Articulation and Phonological Disorders was revised to keep this “classic” reference current and up-to-date. This text does not prescribe a single approach to phonological disorders, but rather presents an eclectic perspective on the nature, assessment, and treatment of this type of communication impairment. The text includes an introduction to the normal aspects of speech sound articulation, normal phonological development, factors related to the presence of phonological disorders, the assessment and remediation of phonological disorders, phonology as it relates to language and dialectal variations, and a chapter on phonological awareness. Discussion questions are presented with each chapter and a new case study is included in the assessment and remediation chapters. As in past editions, this text is primarily concerned with those phonological disorders not etiologically associated with known or obvious sensory, structural, or neuromotor deficits.
