[Autopractice, derealization, activation, and the subject of will]

A more precise definition of control functions should serve to supplement, correct, and complete what has previously been written about the structural dynamic approach. Prehuman stages of development involve autopractical drives and their instinctive inhibition and activation. The human stage involves a differentiation in the direction of drives. A human being's own autopractice remains the moving force, the moving principle. Inhibition and activation have become incorporated in the development of interiority and its structural basis and have freed themselves from instinctual dependency. Little has changed regarding the function of activation. Inhibition has made its way into the realm of the function of derealization; it intervenes as a regulatory principle in human autopractice. The paper concludes with a look at the topic of the will in which it discusses the interplay among the functions of human autopractice, derealization, and activation.
