Introduction to Monograph on Observational Data Analysis

In our introduction, we express our gratitude to Anales de Psicología for publishing this monograph, which embodies many of the achievements that have been made in observational data analysis over the past quarter of a century. Scientific production in the area of observational methodology has improved both quantitatively and qualitatively over this period, helping to overcome the negative perceptions perpetuated by critics who viewed it as a merely descriptive methodology. Another source of satisfaction is the growing interest in the study of everyday behavior from multiple angles and perspectives, and the methodological advances that have paved the way for even further developments. Thanks to this progress, the publication and dissemination of research grounded in observational methodology has reached satisfactory levels. The introduction concludes with a brief description of the articles included in the monograph.
