Abstract
Liz Bates was a pioneer in the study of individual differences in language acquisition and in the development of measures for assessing early language development. Her work was the foundation for my studies of late-talking toddlers. Using her studies of individual differences in rate of development and dissociations between components of language, I conducted a prospective, longitudinal study of a large number of children from 10-months to 7 years of age. The goal was to predict clinically-significant language delay as early as possible. At the younger ages the MacArthur-Bates Communicative Development Inventories were used to measure expressive and receptive vocabulary, use of gestures, and early grammar. Between 5 and 7 years of age clinical diagnosis of language disorder was identified and documented. Between 10-months and 7 years many additional measures of language, cognition, and family history were collected. In this talk I will describe this 10+ year study and suggest a model for early identification of clinically-significant language delay. I will also discuss the differences between and the pros and cons of categorical, dimensional, and individual differences approaches to early identification of clinically-significant language disorders.
