What is Human-Animal Interaction?

Human-Animal Interaction (HAI) refers to any relationship or interaction between a person and a non-human animal. While humans have lived alongside animals for thousands of years, research in this field is relatively new. One key aspect of HAI is the human-animal bond—a mutually beneficial relationship that can influence the health and well-being of both people and animals. Some studies suggest that interacting with animals may improve physical and mental health, as well as enhance aspects of daily life. Similarly, certain interactions may benefit animals, potentially reducing anxiety and promoting better health. However, these effects are not universal, and further rigorous research is needed to fully understand the outcomes of human-animal interactions.

Arizona Canine Cognition Center

The Arizona Canine Cognition Center focuses on studying dog psychology compared to humans, primates, or other animals. The research is driven by the broad questions of what makes animal minds the way they are, how they got that way, and why

HAB (Human-Animal Bond) Lab

The HAB Lab investigates the mechanisms, outcomes, and implications of the human-animal bond. Its research seeks to understand how positive interactions with animals, including those with companion, therapy, facility, and service animals, may lead to therapeutic benefits among vulnerable populations.

BRAY Lab

The BRAY lab researches the cognitive, behavioral, and early environmental factors that affect later life outcomes in dogs. This research, spanning both pet and working dog populations, asks questions ranging in scope from understanding early maternal style to cognitive aging to how genetics contributes to behavioral traits.
