International Groups, Object-relation and the Psychic Group Apparatus The concept of object-relation is a privileged way of access to psychic groupality : it immediately questions the relation of the subject to his or her internal objects while they are themselves in a relationship with other objects. This system of relationship defines a mode of existence of the subject that can be qualified by its investments, its representations, its confliction, its identifications and defense mechanisms towards the objects that constitute it. The group, as an object, is a remarkable figure of the object-relation, especially by the effects of form and structure that assemble it between intra-psychic space and inter-subjective space. It is therefore appropriate to articulate the position of the group as object with internal groupality as a form of the object-relation and with psychic reality specifically produced by the apparatus of psyches in the inter-subjective system of the group.
