We love hearing about the latest findings coming out of an Eötvös Loránd University (ELU) research group focused on gifted word learner (GWL) dogs—if only for the pictures of adorable doggoes playing with their toys. Just last month, we learned that such dogs can learn the labels for new toys just by overhearing their owners talking about those toys. The group is back with yet another new paper, published in the journal Animal Cognition, presenting evidence that GWL dogs have a preference for novel toys and like to share them with their owners. That social interaction seems to be the key to the unique cognitive abilities of these rare dogs.
As previously reported, ELU co-author Claudia Fugazza has been studying canine behavior and cognition for several years as part of the Genius Dog Challenge. For instance, the group’s 2022 study discovered that dogs store key sensory features about their toys—notably what they look like and how they smell—and recall those features when searching for the named toy. Prior studies had suggested that dogs typically rely on vision, or a combination of sight and smell, to locate target objects. GWL dogs can also identify objects based on verbal labels.
Last fall, Fugazza’s group discovered that certain dogs can not only memorize the names of objects like their favorite toys, but also extend those labels to entirely new objects with a similar function, regardless of whether or not they are similar in appearance. It’s a cognitively advanced ability known as “label extension,” and for animals to acquire it usually involves years of intensive training in captivity. But the dogs in this new study developed the ability to classify their toys by function with no formal training, merely by playing naturally with their owners. It’s akin to a person calling a hammer and a rock by the same name, or a child understanding that “cup” can describe a mug, a glass, or a tumbler because they serve the same function.
