The term 'psyche sections' refers to the three parts of Sigmund Freud's psychoanalytic theory of personality. These sections are the ego (EGOS), the id (IDS), and the superego. The ego is the part of the personality that mediates between the demands of the id and the superego, and is responsible for reality testing and a sense of personal identity. The id is the part of the personality that is driven by instinctual needs and desires, and operates on the pleasure principle. The superego is the part of the personality that is responsible for morality and conscience, and operates on the reality principle.
