Editorial

Abstract

The second issue of volume 51 of the Mexican Journal of Behavior Analysis (MJBA) is divided into two sections. The first section comprises the seven articles that make up this issue and are described below. The second section is a supplement to the first, in which several authors collaborated to celebrate the 40th anniversary of the publication of “Teoría de la conducta: Un análisis de campo y paramétrico” [Behavior theory: A field and parametric analysis], authored by Emilio Ribes and Francisco López. The MJBA editorial team hopes that both sections will not only be well-received by readers but will also meet the disciplinary standards that the journal has historically strived to uphold.
