From the educational psychology field, which she defines as bi-dimensional (both theory and practice), the author invites us to understand learners in their human and social nature, the identification of their complexity and what is required from the theory as well as the praxis, in addition to the use of the indiciary paradigm, while the educational psychologists are involved with their own symbolic-cognitive systems on what they intend to know and intervene in. She puts forward a construction of understanding based on the contributions of the social psychogenesis by Dora Laino, which she links up with concepts by authors such as Bleichmar, Urribarri, Lacan, Berenstein, Paín, A. Fernández, L. Fernández, Garay, among others. The text constitutes a reference essay for all of those interested in the teaching-learning processes, especially for those being trained in the educational psychology field.
