Language Development and Language Impairment offers a problem-based introduction to the assessment and treatment of a wide variety of childhood language developmental disorders.
* Focuses for the most part on the pre-school years, the period during which the foundations for language development are laid
* Uses a problem-based approach, designed to motivate students to find the information they need to identify and explore learning issues that a particular speech or language issue raises
* Examines the development of a child’s phonological system, the growth of vocabulary, the development of grammar, and issues related to conversational and narrative competence
* Integrates information on typical and atypical language development
