Robinson, Byron F.; Mervis, Carolyn B.
Journal of Child Language, v26 n1 p177-86 Feb 1999
Compared expressive vocabulary data from a systematic diary study of one child's early language development with data from longitudinal administration of the MacArthur Communicative Development Inventories spoken vocabulary checklist (CDI). The CDI underestimated the number of words in the diary study. Logistic curves were the best-fitting model to characterize vocabulary development measured by the CDI and diary study. (SM)
