Jeffrey R. Stevens

Jeffrey R. Stevens is a Professor in the Department of Psychology at the University of Nebraska-Lincoln and a core faculty member at the Center for Brain, Biology, and Behavior. He directs two research labs: the Adaptive Decision Making Lab and the Canine Cognition and Human Interaction Lab. His work integrates cognitive and evolutionary perspectives to study decision-making in humans and animals, with a focus on intertemporal choice, social behavior, and comparative psychology.

Stevens' research spans diverse topics including

• Animal cognition (primates, birds, and canines)
• Neuroendocrinology (mesotocin's role in prosociality)
• Behavioral economics (temporal discounting, opportunity costs)
• Machine learning applications in psychological measurement

His recent publications examine quantitative sensitivity across species, exercise's impact on food choices, and social bonding mechanisms in pinyon jays. He has developed computational tools like the 'excluder' R package and contributed to journals such as Nutrients and Animal Behavior and Cognition as an associate editor. Collaborative work with interdisciplinary teams highlights his commitment to integrating psychological and biological frameworks.
