The aim of this dissertation is to analyze the changes that take place within the analytic setting – and a possible complexification of the analyst s psychic work – when the analysis refers to a narcissistic-identity disorder. These clinical cases confront the analyst with the need to broaden his listening skills to recognize non-verbal communication (body and affect) as messages coming from an ancient time before language acquisition. Considering this form of communication as a specificity of this type of clinical encounter, it is important to highlight the great significance of the object and the quality of his responses in the subject s past history as well as within the analytical relationship to facilitate the development of the symbolization processes and/or to let them resume their course. The analyst plays a more active role within the analytic relationship, being aware of the potential messages originating from other sources – body and affects. The expansion of the analytic method opens the possibility of defining intersubjectivity as a key moment for the construction of the subjectivity. In other words, the process of subjectivation depends on the quality of the relationship established with a fundamental other and it is of utmost importance to recognize its clinical value.
