Editorial

This first issue of Volume 51 of the Mexican Journal of Behavior Analysis (MJBA) is of special significance, as it includes a collection of manuscripts honoring Professor Kennon Andy Lattal, an experimental and applied behavior analyst with a long career and significant contributions, always adhering closely to the theoretical and methodological approaches that define both strands of B. F. Skinner's conceptual proposal. The special section honoring Dr. Lattal was proposed as a complement to the award presented to him by the Mexican Society of Behavior Analysis in 2021 for his work as English-language editor of MJBA. The task of gathering and editing the manuscripts was in the hands of Andy's colleagues and friends, Drs. Laura Acuña and Carlos A. Bruner (RIP).
