Encounters and collisions of inner worlds Interpersonal, intersubjective, interpsychic and transpsychic

This study examined the interpsychic, presubjectual, and prepersonal exchange processes that form the origin of the primary relationship. They are based on physical correspondences between the interaction partners. These processes are distinguished from intersubjective processes, which presuppose the presence of a coherent subjective self. They are also different from interpersonal processes that imply the presence of a differentiated identity consciousness in relation to the other. The competence in dealing with these interpsychic exchange processes requires the analyst's ability to use the area between self and non-self with sensitivity, as well as the creative dimension which is typical for the preconscious. This allows the transition of inner elements from one interaction partner to another. Such transitions are ubiquitous in psychoanalytic treatment; however, they have been studied relatively rarely and are hardly known in the literature.
