Tests and other assessment procedures are discussed and therapeutic strategies suggested. Thus, psycholinguistic approaches such as ITPA, the Reynell Developmental Language Scales and the Aston Index; linguistic techniques such as LARSP and phonological assessments are described, and adult disorders as well as childhood problems, are reviewed. There is also a brief consideration of the problem of assessing the language of those not speaking English as a first language. The book serves as a core text for student speech therapists and also as a reference for those practicing or researching in speech therapy, special education and linguistic pathology.
