The first attempt is being made to synthesize fundamental, cultural, and practical psychology, focused on a transactional and analytical interpretation of personality (the “TA-model”). The professional language of transactional analysis, the identification and names of “games” and life scenarios, the very stylistics of Berne's texts: all these are a manifestation of the effect of the presence of the cultural phenomenology of personality in transactional analysis. The as yet undisclosed resources for the operationalisation of TA categories, and their interpretation from a general psychological standpoint, hypothesis testing, the updating of contexts for the use and modification of known research methods, all act as motivation for the inclusion of transactional analysis in the context of fundamental personality psychology. The work of the creator of transactional analysis, who demarcated the lines for the theoretical comparison of TA with both complementary and oppositional systems of psychotherapy, remains an under-explored field of research, at the same time that their mutual rapprochement and mutual germination are occurring in a “natural manner”. It may prove possible within the scope of scientific research to “spy out” the common elements of the work of representatives from various fields and schools of psychotherapy, and to evaluate them in order to present the results of this meta-analysis to the counsellors themselves, as a psychological tool for the development of their own behaviour and consciousness. Such is the “challenge” of the TA-model of personality in the context of counselling psychology.
