Emotional aspects of human interaction with domestic animals: neurobiology of attachment and social regulation Introduction: Interspecies emotional symbiosis Interactions between humans and domestic animals represent a unique form of interspecies social connection that profoundly affects the emotional sphere of humans. This phenomenon goes beyond simple utilitarianism (protection, assistance) and is based on complex psychophysiological mechanisms that have evolved both in humans and domesticated species. Scientific analysis of these aspects requires an interdisciplinary approach, including ethology, social psychology, neurobiology, and anthropology. Neurochemical bases of attachment: the oxytocin circuit The key mediator of emotional connection between humans and animals is oxytocin — a neuropeptide often referred to as the "bonding hormone," "love hormone," or "trust hormone." Reciprocal stimulation: Studies (such as the work of Japanese neurobiologist Takefumi Kikusui) have shown that when humans and dogs gaze at each other "eye to eye," the level of oxytocin increases in both. This mechanism resembles the mother-child attachment system. In cats, despite their reputation as independent animals, tactile contact (petting) also elicits an oxytocin response in humans. Effect of "baby" features (baby schema): Many domestic animals, especially puppies and kittens, possess atypical features (large head, large eyes, rounded shapes) that activate the innate care mechanism (caregiving system) and associated positive emotions (tenderness, compassion) in humans. This triggers the release of oxytocin and dopamine, creating a sense of pleasure from interaction. Interesting fact: In one experiment, dog owners who received intranasal oxytocin spent more time petting their pets and looking at them in the eyes, which, in turn, increased the level of oxytocin in the dogs. This demonstrates the existence of a positive interspecies biochemical feedback loop. Emotional regulation and a ... Read more
