More than half of people in the world speak at least two different languages, says Kohnert (emeritus, speech-language-hearing sciences, U. of Minnesota), and many children and adults suffer from primary language disorders. She explores the intersection between the two groups. Her goal is to extract core principles and frameworks from the empirical, theoretical, and professional literatures that can guide meaningful clinical actions with bilingual people. Her emphasis is on a rich context for critical, creative, and effective clinical actions, rather than on prescribing specific procedures. She writes for speech-language pathologists, advanced students in communication sciences and disorders, and clinical language researchers. The first edition was published about five years ago.
