Taking a functional approach, focuses on children's language problems from a holistic perspective. Unlike other language disorders books, it moves logically from assessment through intervention emphasizing universal techniques that work for all delays and disorders. With over 1200 new references, it provides a strong theoretical background and emphasizes evidence-based practices. This edition includes a new chapter on early communication intervention, more on language analysis, coverage of Specific Language Impairment, and more on augmentative and alternative communication.
