<entity_1> (German: <entity_1>), according to psychoanalyst Sigmund Freud, is a <entity_0> leading to the temporary or long-term reversion of the ego to an earlier stage of development rather than handling unacceptable impulses in a more adaptive way. The <entity_0> of <entity_1>, in psychoanalytic theory, occurs when an individual's personality reverts to an earlier stage of development, adopting more childish mannerisms. Kris thus opened the way for ego <entity_2> to take a more positive view of <entity_1>.
