title: [Age and analytic-synthetic activity of school-children solving problems with an elementary pattern].
abstract: Schoolchildren of 1--10-th grades solved the tasks with one and the same elementary scheme, in which the appearance of the given signal followed one action out of 14 possible ones. When the task was presented in the form of buttons and lamps its solution did not improve with age. Moreover, 4--5-th grades' pupils solved it quicker than the senior ones. When the scheme consisted of symbols the task was solved better with age. Junior schoolchildren solved it much slower than that with buttons and lamps. This difference diminished with age, and senior pupils solved both types of tasks equally. The obtained data result from formation in the ontogenesis of abstract-logic connections with different degree of generalization, reflecting the relations between the stimuli in the experimental environment.
