The author argues that construction of any new action is invariably accompanied by differentiation of its motor stage, which results in emergence of a heterogeneous subtle inner structure consisting of substructures - action quanta. Each substructure includes its own microprogram, motor and control stages. The structural transformation leads to the motor stage being filled with cognitive formations which become the true moving force for formation of the image and action program, adequate to a new situation. The author proves that organization and perfection of an action are achieved by means of overcoming the chaotic differentiated structure produced by the individual.
