The study described concentrated on three tasks of operating unknown systems of differing degrees of complexity in order to reveal characteristics of development of intuitive experience in subjects, i.e. understanding of regularities of the functioning of the system and modifications in the process of operating the system. In all cases it has been discovered that intuitive experience is a modification of the operation process which consists in actions aimed at discovering the solution algorithm based on implicit determination of features of the system essential for achieving the goal. Implicit unconscious knowledge of regularities in the functioning of an unknown system is not formed in the process of operating the system.
