Summary
In the course of the study, it was determined that full-fledged activity, i.e. intellectual activity of the highest level, cannot develop without relying on previous methods of performing any mental operation and, ultimately, its original, complete and without a comprehensively developed practical mechanism of execution. At the same time, it was determined that there are four parameters that create intellectual activity: the level of performance, the degree of generalization, the completeness of the operations actually performed and the method of assimilation. In connection with these parameters, the levels of activity organization were also determined, it was shown that in the period from 2 years to adolescence, verbal generalizations acquire the form of concepts, turning first into primary concepts for “oneself” and “others”, and then into the main concept “for oneself”.
