Socioendocrinology is a field of research that focuses on the interactions between hormones and social behavior in animals and humans. It examines how hormones, such as cortisol, testosterone, and oxytocin, influence social relationships, dominance hierarchies, mating strategies, and other social interactions. Researchers in this field study how changes in hormone levels can impact behavior and how social experiences can in turn affect hormone production and regulation. Socioendocrinology has implications for understanding a wide range of social behaviors, including aggression, cooperation, and mate choice.
