Which Freudian concept corresponds to the part of personality that tests reality and mediates between instinct and external world?

• A. Id
• B. Superego
• C. Ego
• D. Oedipus complex

Answer: (C)

The ego is the part of personality that operates in reality. It tests what’s possible in the real world, delays gratification, and finds realistic ways to satisfy the id’s impulses without breaking social norms or causing excessive anxiety. It mediates between the instinctual desires of the id and the moral constraints of the superego, using the reality principle and conscious thought to plan actions. The id is the source of instinctual drives, the superego imposes moral standards, and the Oedipus complex is a psychosexual stage rather than a structural mediator. So the element that tests reality and bridges the gap between inner urges and the external world is the ego.
