I think my horse knows the sound of my aging diesel Smart car. She seems genuinely pleased to see me, and on rare occasions has offered a soft nicker at my arrival โ€“ a gesture guaranteed to instantly melt my heart. But does she love me?

In psychology, the question of love has been most extensively explored through attachment theory, first proposed by John Bowlby in the early โ€˜60s to explain an infantโ€™s tendency to seek proximity and form strong bonds with a caregiver who provided protection, comfort, and support. Bowlby believed that the attachment system evolved to increase the infantโ€™s chance of survival.

Although horses do not have the same kind of dependency on their human as an infant does for a parent, they do rely on us to some extent for their survival, and might well form an attachment bond with their caretakers. There is also adaptive value in forming a bond with someone of higher in the heirarchy to have ready access to oneโ€™s own bodyguard and a first-class ticket to desired resources. Since many horses today have limited or no opportunity to form attachments with other horses, it is possible that they may just settle for the next best thing โ€“ their human. But do they form an enduring bond for one particular human as Bowlby defined an attachment relationship? Ahh well โ€ฆ as my scientist colleagues would say, that is an empirical question. Letโ€™s take a look.
