In line with the work plan of the current editorial team of the Mexican Journal of Behavior Analysis (MJBA), the first issue of volume 52 is dedicated to celebrating not only the work of Professor Anthony Charles Catania but also his 90th birthday. Aside from the canonical manuscripts within behavior analysis of which the honoree is the author (e.g., Catania, 1966, 1969, 1979, 1985), co-author (e.g., Catania & Reynolds, 1968), or editor (e.g., Catania & Harnad, 1988), in Mexico many psychologists know his name and at least some of his work through the Spanish version of his compilation Contemporary research in operant behavior (Catania, 1968/1980); a book that is simply irreplaceable for the teaching of psychology, for which I don't think it is an exaggeration to express our deepest gratitude.

Abstract Animals typically prefer choice alternatives that deliver food with a higher probability. However, previous research has shown that some animals will choose a lower probability alternative when it contains a signal about when food will be delivered, a phenomenon sometimes called suboptimal choice. Although this finding has been repeatedly demonstrated in pigeons, results with rats have been mixed, indicating that the stimulus modality may influence choice. In the current study, female rats' choices for delayed and probabilistic food were examined using a concurrent‐chains procedure, with olfactory terminal‐link stimuli. In Experiment 1, four of six rats preferred the lower probability alternative. In Experiments 2 and 3, a statistically significant group‐level preference for the lower probability alternative was observed, despite increasing the number of free‐choice trials in a session and reversing the location of the choice options. Data on the number of pellets rats earned across the three experiments were tracked to quantify how rats' proportion choice of the lower probability alternative affected the number of pellets earned during each session, providing insight into how much food rats are willing to forego for a choice alternative with a predictive stimulus.

Abstract This brief paper addresses the significant but often overlooked issue of invisibility and vulnerability faced by international Latin American female students (ILAFS) in the U.S. Drawing upon existing literature, the paper highlights the lack of research and attention given to this specific population, resulting in limited understanding of their unique challenges and needs. It emphasizes the importance of behavior analysts in supporting these students by serving as advocates for ILAFS, by understanding their unique needs and the role of intersectionality, facilitating their academic success, cultural and social adaptation, and well-being. By shedding light on this underserved population and advocating for their needs, behavior analysts can contribute to creating more diverse, inclusive, and equitable environments.
