The theory focuses on Consciousness and Unconsciousness, Driving forces of personality, Components of personality, Stages of personality development, types of personality, and Internal frame of references of a person.This theory defines The Conscious memory as all those sensations and experiences to which we are aware of at any given time. Some part of our memory is called preconscious memory which is the "available memory," it contains all the experiences that are not conscious at any given time but which can easily be summoned into awareness with a little effort. While Unconsciousness is that part of our psyche of which we are not aware at any given moment. This is the deepest and biggest part of the human mind. Unconscious memories are the ones that are completely inadmissible to awareness, but yet they largely determine the actions of people.The personal unconscious consists of those repressed or forgotten or not vary clear memories. It consists of chunks of emotionally loaded thoughts which are also called complexes. The Collective Unconscious refers to our ancestral experience. these are the memories from untold thousands of years, so it is the fragments of all of the human history which we inherit from our ancestors.One of those driving forces is Libido. Libido is the general biological life energy it is used in solving different problems. Libido is also the creative driving force of human personality which helps in continuous psychological growth of the individual, when we have to perform activities such as sleeping, studying, eating, walking, and talking, all these activities require energy and Libido is the storehouse which provides us with that energy for all our psychological and physical needs. At an organic level, this tendency which is inborn involves the maintenance of the person by fulfilling deficiency needs like air, water, and food but also the enhancement of the organism by providing energy for the development of the body’s organs and functions.
