Talking Bark: Properly Trained Pups Really Can Understand Us
WASHINGTON — Is talent in a given field a uniquely human phenomenon? A recent study shows how dogs (man’s best friend) hold an exceptional talent for learning words.
A new study, published in Scientific Reports, found that, while the vast majority of dogs struggle to learn object labels (such as the names of their toys), when tested in strictly controlled conditions, a handful of gifted word learner dogs learn multiple toy names, apparently effortlessly.
A team of researchers of the Family Dog Project at the Department of Ethology, Eotvos Lorand University, Budapest, exposed 40 dogs to an intensive, three-month-long training program aimed at teaching them the name of at least two dog toys — which is the minimum amount necessary to be able to assess whether dogs can tell the items apart based on their names.
The training protocol included daily playful interactions between the dog and the owner, during which the owner repeated the name of the toy several times, and weekly sessions including also a dog trainer.
“At first, we hypothesized developmental factors, such as neuroplasticity during puppyhood,” said Claudia Fugazza, leading researcher of this project.
“It would have played a role in making puppies learn object names at a faster rate, compared to adult dogs. Thus, we recruited for this study puppies and adults,”
“We were surprised to find that, despite the intensive training, most dogs, irrespective of their age, did not show any evidence of learning. Even more surprisingly, seven adult dogs showed an exceptional learning capacity.”
“They did not only learn the two toy names but, within the time of the study, they learned between 11 and 37 other novel toy names,” continued the researcher.
Among these seven dogs, six already possessed a vocabulary of toy names when the study began. The seventh dog, named Oliva, did not previously know toy names but learned 21 in only two months, keeping pace with the other six gifted word learner peers.
This may suggest that the exceptional capacity to learn object names does not necessarily presuppose prior experience.
“All the seven dogs that showed this exceptional talent are Border collies, a breed meant to cooperate with humans for herding purposes,” said Shany Dror, co-author of the study.
“But it is important to keep in mind that, within the many dogs that did not show any evidence of learning, there were also 18 Border collies.”
Moreover, in the literature, some dogs of other breeds are reported to have acquired vocabulary knowledge.
For example, a study found this capacity in a Yorkshire terrier. Although it may increase the chances, being a Border collie is not necessary, nor enough to be a “gifted word learner dog.”
“We are intrigued by this extreme inter-individual variation in a cognitive trait (the capacity to learn object labels),” said Adam Miklosi, head of the Department of Ethology and co-author of the study.
“We think that this is just the beginning of a journey that will lead us to understand the roots of talent better, and that is why some individuals — humans or other species — are gifted in a given field,” Miklosi said, who thinks that dogs, constitute the ideal model species to take up the challenge to study the origins of talent and variation across individuals in cognitive capacities.
