This monograph brings together the presentations published in the INFAD Journal over the period 2006–2026. This compilation reflects an interest in preserving, organizing, and highlighting a collection of texts which, beyond their introductory function in each issue, constitute a record of the editorial thinking that has guided the journal under the direction of its Director-Editor, Dr. Florencio Vicente Castro. Through these presentations, it is possible to observe the evolution of INFAD’s scientific identity, its priority thematic areas, its openness to new research contexts, and its commitment to the dissemination of knowledge in the fields of Developmental Psychology, Educational Psychology, and other related disciplines. This volume is not intended to replace the original value of each presentation as published in its respective issue, but rather to provide an overall perspective that enables readers to understand the journal’s trajectory, its scientific concerns, and its continuity over time. In this way, the monograph is conceived as a work of compilation, institutional memory, and forward-looking projection.
