From a dialogical and Bakhtinian theoretical stance, identity is seen a process and a product of the tensional relation between multiple perspectives or positions. Even in the midst of different dialogical approaches to the self, there is an overarching consensus that the dialogical dynamics established by these different positions are a core element for understanding how identity works. One of the main problems of the field has been the development of empirical methods enabling the study of such dynamics. Positioning Microanalysis is a method based on a dialogical approach, which aims the systematic tracing by trained observers of the dialogical dynamics of self-positions as they unfold over time. This method assumes a genetic-developmental perspective, allowing the study of self-positions taking place in the here-and-now in a moment-by-moment basis. The main unit of analysis is the emergent self-position, which is characterized by a basic triadic relation (I-Other-Object). This method, on a first level of analysis, depicts the microgenetic movements of self-positions from moment to moment, but it also allows for more macrolevels of analysis, by describing stable sequences or cycles of positions. Thus, it may be used as a tool for the study of identity in a given historical moment of the person regarding specific themes or relevant “objects.” This method will be illustrated by its application to the first session of a psychotherapy case.
