In this sequel to their Milestones course (Plural, 2006), Oller (U. of Louisiana) and his co-authors present a dynamic systems- oriented approach to communication disorders. They re-classify disorders of systems of representation according to new empirical and theoretical work, and treat aspects from anatomy and assessment to advocacy and ethics. Chapters also highlight controversies, e.g., the current ones over the autism- mercury link and late-term abortion for fetuses with deformities, and the longstanding one over deaf-mute Helen Keller's achievements. The text features case examples, study and discussion questions, a glossary, and DVD with video recordings and an exam. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
