NORMS OF GRAMMATICAL CATEGORIES ACQUISITION BY BOYS AND GIRLS AT AN EARLY AGE (BASED ON MACARTHUR QUESTIONNAIRE)
The article is devoted to the morphological norms of speech development of children at an early age. The significance of the topic of the article can be attributed to the need to know the norms for objective assessment of children’s speech and prospects for its future rehabilitation. This article uses a standardized scale - The MacArthur Communicative Development Inventory, based on questionnaires filled in by the parents. The Russian MacArthur CDI was сreated by a group of authors: M. B. Eliseeva, E. A.Vershinina, V. L. Ryskina, S. N. Ceytlin. The study was carried out from 2000 to 2012. The Russian version of the CDI included data from 1805 questionnaires about typically developing children aged 8 to 36 months (902 girls and 903 boys). The speech development norms were calculated on the basis of distribution of total scores in each section of the questionnaire using percentiles, and specifically medians, and on the frequency of uses of certain linguistic categories.Complete normative data on the morphological development of speech of children at an early age are published and analyzed in this article for the first time. The authors present gender norms of the development of some morphological categories of the noun (case and number) and the verb (tense and person). The norms calculated can be used for speech diagnostics of both children with typical development and children with speech dysontogenesis.
