ego

1. the self, particularly the conscious sense of self (Latin, “I”). In its popular and quasi-technical sense, ego refers to all the psychological phenomena and processes that are related to the self and that comprise the individual’s attitudes, values, and concerns.

2. in psychoanalytic theory, the component of the personality that deals with the external world and its practical demands. More specifically, the ego enables the individual to perceive, reason, solve problems, test reality, and adjust the instinctual impulses of the id to the demands of the superego. See also antilibidinal ego; body ego.
