A recent study conducted by researchers at the University of Padova found that horses often prioritize positive human interaction over receiving larger portions of food. This discovery challenges the common assumption that animals are primarily motivated by hunger when making choices.

In the experiment, horses were initially presented with a choice between two food portions: a half apple and a quarter apple. Those that consistently selected the larger portion were then advanced to a subsequent phase involving social cues from humans. During this stage, the horses were introduced to two unfamiliar women who each offered a portion of apple. One woman displayed friendly behavior—smiling and making eye contact—while offering the smaller quarter apple. The other woman exhibited a detached demeanor, avoiding eye contact and appearing disengaged, yet offered the larger half apple.

When the horses were given the opportunity to choose between the two women simultaneously, the majority selected the friendly individual despite the smaller food reward. This behavior suggested that the animals found the emotionally positive social interaction more rewarding than the larger quantity of food.

The researchers published their findings in the journal Animal Behaviour, highlighting that horses place significant value on affiliative human contact, even when it conflicts with basic food motivation. This insight into equine preferences underscores the importance of social bonds between humans and horses, with potential implications for animal handling and welfare.

Overall, the study indicates that horses may seek out connections with humans as a form of enrichment, emphasizing the role of emotional engagement alongside traditional rewards like food.
