Trauma and regression are concepts that have always raised some debate and controversy in Psychoanalysis. Throughout the present thesis, the development of both will be analyzed in Freud s theories and also in some of the main authors on the early object relations, among which Donald Winnicott and Michael Balint stand out for improving the changes made in the analysis theory and techniques developed by Sàndor Ferenczi. The two enlarged in an inventive way the theoretical scope around certain clinical phenomena that bring about unique subject suffering. In this line of thought, this paper aims to associate some reflection to other fundamental concepts proposed by these authors; more specifically, the concepts of primary love and of basic fault in Balint, and those of holding and transitional phenomena in Winnicott. On this ground, it can be concluded that the clinical-theoretical thinking based on the relational model has enabled a better apprehension of the processes which are essential in the psychic constitution and in the various ways to take power over and elaborate on trauma, in which understanding of the analytical situation, as an unconscious common ground turns out to be relevant for the therapeutical process.
