 Through this process of restraint and confrontation, therapists seek to produce in the child a range of responses such as rage and despair with the goal of achieving catharsis.In theory, when the child's resistance is overcome and the rage is released, the child is reduced to an infantile state in which he or she can be "re-parented" by methods such as cradling, rocking, bottle feeding and enforced eye contact.The aim is to promote attachment with the new caregivers.
