The psychodynamic approach views the mind as consisting of three levels - the conscious, preconscious, and unconscious. Freud likened the levels to an iceberg, with the conscious mind above water, the preconscious below the surface but visible, and the bulk of the unconscious mind unseen below. According to Freud's structural model, the id seeks pleasure instinctually, the ego balances id impulses with reality, and the superego incorporates moral standards from parents and society.
