Expelling is one of the transactional modes described by Stierlin (1974). The expelling mode may be seen as the opposite of the binding mode. Both of these modes become evident in the context of separating parents and adolescents. Like its opposite, the expelling mode is variously effective on different levels and can be approximated by the psychoanalytic concepts of an id level, an ego level, and a superego level.
