The developmental levels of verbal and non-verbal intellect as compared to the characteristics of analytic-synthetic activity in 6-year-olds were experimentally investigated. The instructions were given in abstract (1 stage) and in concrete-graphic (2 stage) forms. It was shown that (1) preschoolers' analytic-synthetic activity was closely connected to their intellectual characteristics and (2) educative efficacy is influenced not only by the developmental level of intellectual and analytic-synthetic activity, but by their components ratio.
