The author hypothesizes that 'the less structured by purpose or by directive leadership a group is, the more capable it is of inducing regressive tendencies and anxiety', and that 'the less structured by extrinsic tasks, activities, purposes or goals a group is, the more capable it becomes of gaining awareness of psychological relationships among its members'. Accordingly, developmental and training groups are found to develop immediate awareness in participants, while therapy groups serve to reveal and to work through unconscious conflicts as observed in the participants' mutual relationships.
