Imagination is presented as a mental activity underlying the ability to produce images of any situation up to the image of the world as a whole. Imagination is developed in the process of every activity, and the more completely the activity encompasses the situation the better is the result. Apart from the goal-directed activity of the child himself, of much importance in the promotion of imagination is the participation of an intimate adult who cooperates with the child and controls him. Imagination can be developed only in the process of developing the mind and the personality of the child in general by means of introducing him to different sorts of man's activities (especially artistic ones). In addition to the principle of totality (from the total to its parts) organization of imagination must be based on positive emotions which result from successful performance and from the joy of communicating with the beloved adult.
