Intended for teachers and speech clinicians, the handbook and accompanying worksheets describe research-based psycholinguistic procedures for needs assessment and individualized instruction of language-delayed children, including aphasics. Four main chapters explain how to collect a language sample (a systematic transcription of the student's spoken responses); how to analyze the sample (including instructions for counting words and classifying sentences); how to write training programs based on analysis of the sample; and how to conduct, record, evaluate, and report the results of training programs. Examples of instructional techniques are offered throughout the text. Also provided is a glossary of linguistic and behavioral terms. Five appendixes contain instructions for counting morphemes and categorizing sentence constructions, analyses of two samples from language-delayed children, and a practice exercise in sentence classification (with answers).
