Auxiliary ego

An auxiliary ego, also known as simply an auxiliary, is the position taken by other participants in a role-playing exercise, or psychodrama, in order to simulate particular situations for the protagonists. As role-playing can include more than one protagonist, each may be operating in the role of auxiliary ego to each other as the exploration of each role changes with the entrance of new situations. The director of the role-play, often a teacher or counselor, can also be an auxiliary and typically is when clients are in the position of protagonist.
