unwittingly use Freud's and Skinner's ideas in their conduct and encounter the underlying principles of these two theories in everyday life, but the theories take on a different form when directly applied to interpretation of behavior.
             In the psychoanalytic theory, the unconscious is necessary, indeed vital for the existence of the drives and desires that rest within it. This much-attacked entity inhabits the repressed id functions, primitive impulses, memories, images and wishes that provoke anxiety and therefore cannot be accepted into the conscious domain of the mind (Reber, 1985).
             The unconscious domain is needed to account for one's behavior. Many psychological processes occur within one's mind that lead to the performance of certain acts. Sometimes the motivation behind these acts cannot be found within the consciousness and the consciousness offers no evidence of the existence of those motivations. Evidently, the consciousness fails to offer an explanation for some things and it is for this reason that the unconscious is essential in the interpretation of behavior and personality (Freud, 1984).
             The proof of the existence of the unconscious lies in the observation of the use of the knowledge acquired during one's lifespan. A person is not continually aware of all information they have acquired. Only certain information is selected to be actively used and that resides in the consciousness. The rest is " psychically unconscious " (Freud, 1984: p 168). It is for this reason the existence of the unconscious cannot be denied (Freud, 1984).
             The domain of the mind known as the 'id' is the true unconscious (Freud, 1984). It is the home of the "uncoordinated instinctual trends" (Freud, 1984: p 22), drives, desires and wishes which seek to be gratified, to obtain pleasure. The id is lead by the pleasure principle, but it itself encounters a barrier: the ego. Ego is the part ...
