This is the leading text for courses in clinical phonology--thoroughly revised and updated to include the most current and up-to-date information in the field. Even the newly added subtitle, Speech Sound Disorders in Children, reflects recent changes in the field, including new terminology. This classic text does not prescribe a single approach to phonological disorders but rather presents an eclectic perspective on the nature, assessment, and treatment of this communication impairment. The addition of a third author, Peter Flipsen Jr., a highly-recognized scholar in the area of clinical phonology, brings important, new information for readers and fresh perspectives to the text.Among the many highlights and special features of the sixth edition are: An entire section devoted to the classification of speech sound disorders; The latest information on Childhood Apraxia of Speech, including a detailed discussion of the 2007 ASHA position statement; A revised and updated comprehensive chapter on Normal Development; A full section on measuring clinical change set within the context of evidence-based practice; An outstanding summary of phonological acquisition information written by leading researcher in this area, Sharynne McLeod; Comprehensive coverage of dialects and phonologic characteristics of speakers with first languages other than English, prepared by leading authorities in this area, Brian Goldstein and Aquiles Iglesias; A completely updated chapter on phonological awareness, co-authored by Laura Justice, Gail Gillon, and C. Melanie Schuele; A fully comprehensive and current review of etiological variables, thorough discussion of the assessment of phonologic disorders, and an updated review of broad-based intervention methodologies; and every chapter features introductions, summaries, charts, and graphs to guide learning and aid students' comprehension. The sixth edition of Articulation and Phonological Disorders: Speech Sound Disorders in Children proves once again its "classic" status, and its rightful place on every speech, language, and hearing clinician's bookshelf.
