Note: Thus, the development of creative potential as the main goal of academic education can contribute to the formation of a successful specialist in a wide range of practical, complex tasks of the professional environment. The connection between intellectual potential and the motivational sphere of personality has been repeatedly emphasized in cognitive psychology. Thus, in the classic works of J. Piaget, one can find the propositions that cognitions (as constituent elements of thought processes) and motivational states are two sides of the individual’s activity: cognition describes the structural and the motivation describes the energy aspect of the action. The internal motive force of the individual’s cognitive activity is, according to Piaget, the processes of permanent imbalance and the desire to restore it. Therefore, cognitive structures already contain an energetic, motivational component. This is the main difference between the cognitive concept of Piaget and his followers from behavioral theories that explain the emergence of motivation by external reinforcement. The system of classical education is built, as is known, on the postulates of objective behaviorism.
