Solution:The concepts of id, ego, and superego are proposed by "Sigmund Freud" in his 'Psychoanalytic Theory of Personality'. Freud used these three concepts to describe the three parts of the human personality and to explain the way a human mind works.
According to Freud, the human personality is made up of three major systems: the id, ego, and superego. These three systems work together cooperatively and constitute a well-organized personality in a person and enable the person to interact with the external environment.
The ID:
It is the unconscious part of the human personality that works to fulfil basic desires.
It is based on the pleasure principle which aspires for the satisfaction of antisocial desires.
It is the basic personality component that is present since birth and seeks to satisfy sexual wishes.
The Ego:
It looks for rules and morals and resides in the unconscious mind.
The Ego always postpones the desire and to discharge the tension until it gets the desired object.
It is that aspect of personality, which strives to be logical and reasonable and to cope with the world of reality.
The Superego
It is the moral part of the personality, which is also known as conscience. It stands for perfection, rather than pleasure.
It acts as a balance between id and ego, it tries to figure out the solution which does not hurt either id or ego.
The Superego develops in the child's mind as a result of its response to the rewards and punishment adopted by the parents.
