There are three kinds of imagination:
Productive Imagination. Also, referred to by Kant as transcendental imagination, whose function is to synthesize, by means of the a priori categories, the manifold experience. It is spontaneous and a priori. By the help of this faculty one is able to experience the world of senses in a meaningful way.
Reproductive Imagination. It is the power of reproducing images stored in the memory under the suggestion of associated images. (Random Dictionary)
Creative Imagination. It is the power of recombining former experiences in the creation of new images directed at a specific goal or aiding in the solution of problems. (Random Dictionary)
