Austrian physician Sigmund Freud (1856)founded the psychoanalysis theory which views sex, aggression and the unconscious as being majorinfluences on behaviour.Freud believed the mind operated on three levels: unconscious, preconscious, and conscious and that the mind was composed of three elements: the id, the ego, and the superego. He also looked at the psychosexual stages of development and the use of defense mechanisms
Freud used the metaphor of an iceberg to describe human personality. The visible tip of the iceberg representsthe conscious, the submerged middle represents the preconscious and the larger submerged bottom represents the unconscious.

The preconscious contains informationthat we are not thinking of at the moment but can easily draw into conscious awareness like remembering a pin number or phone number. The preconscious acts as gatekeeper between the conscious and unconscious. It allows only certain pieces of information to pass through and enter conscious awareness.The conscious mind includes everything that is inside of our awareness. This is the aspect of our mental processing that we can think and talk about freely. The conscious mind includes such things as perceptions and feelings inside our current awareness.

The ego is governed by reality and is responsible for reconciling the
