In this current and well-organized text, Plante and Beeson provide an introduction to the field of communication disorders that engages students' interests in professional practice and welcomes them into the major. This new edition retains the strong introduction to communication processes and disorders of the First Edition. The text presents a life-span perspective on disorders from infancy through geriatrics, covering both normal development and disorders. Each chapter reflects insights gained from firsthand clinical research and teaching experience across a variety of clinical populations. The focus on the professions of speech-language pathology and audiology are conveyed through clinical cases, discussion of professional issues, and vignettes of professional interactions in a variety of work settings. This broad-based introduction presents the range of content central to the professions, yet maintains a consistent, easy-to-comprehend style and unified voice.
