Шепот раньше губ, или что предшествует эксплозии детского языка
The paper focuses on W. Humboldt's thesis on the internal forms of language and on G.G. Shpet's thesis on the internal forms of word. These theses are applied to the internal forms of action and image. The author shows the heterogeneity of word, image and action and provides data evidencing their heterogenesis in the developmental processes, age-related as well as functional. In the first stages of child development a word is born as the internal form of movement, action and image. When it is released, it carries along action and image as its inner form within which it was initially born and developed. The paper also gives some data supporting G.G. Shpet's hypothesis that word is not 'third in line' after senses and mind, but is the only origin of knowledge that embraces all others as a cognitive whole.
