Children with specific language impairment (SLI) show a significant deficit in spoken language that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. More prevalent than autism and at least as prevalent as dyslexia, SLI affects approximately seven percent of all children; it is longstanding, with adverse effects on academic, social, and (eventually) economic standing.

Approximately five percent of all children are born with the disorder known as specific language impairment (SLI). These children show a significant deficit in spoken language ability with no obvious accompanying condition such as mental retardation, neurological damage, or hearing impairment. Children with Specific Language Impairment covers all aspects of SLI, including its history, possible genetic and neurobiological origins, and clinical and educational practice.

The study of child language and, in particular, child syntax is a growing area of linguistic research, yet methodological issues often take a back seat to the findings and conclusions of specific studies in the field. This book is designed in part as a handbook to assist students and researchers in the choice and use of methods for investigating children's grammar. For example, a method (or combination of methods) can be chosen based on what is measured and who the target subject is.
