Dogs can distinguish between two different languages: Research

Researchers in Hungary have found that the brain activity of dogs varies when they hear a familiar or unfamiliar language.

A new study of brain images has shown that dogs have the ability to recognize words and distinguish between different languages.

Researchers in Hungary have found that the brain activity of animals varies when they hear a familiar or unfamiliar language.

The authors of the study say that this is the first time that it has been discovered that a non-human brain can distinguish between two languages.

18 dogs were trained to lie motionless in a brain scan machine. Here he was quoted in both Hungarian and Spanish novels, The Little Prince.

All the dogs in the study had heard only one of the two languages ​​from their owners before the experiment.

Dogs were also given mixed quotes to see if they could distinguish between words and words spoken in obscure form.

When the researchers compared the reactions to words or obscure material, they found that dogs had different brain activity.

The researchers specifically found that different activity was found in the basic part of the brain that recognizes sound in dogs.

There was a distinction between whether the stimuli came from a familiar or unfamiliar language, but no evidence was found that the dog's brain prefers words to obscure words.

Research has shown that in addition to recognizing speech or spoken words, a dog's brain can also distinguish between Spanish and Hungarian.

Patterns of language activity were also found in other parts of the brain that recognize sounds. The researchers were surprised to learn that the older the dog, the greater its ability to distinguish between human and non-human language.

One of the study's authors, Laura Kwaiya, also included her dog in the study, whose name is Qin.

He added: "Every language is characterized by a variety of auditory similarities. Our results show that while living with humans, dogs learn the auditory similarities of the language with which they interact.

According to Attila Index, senior author of the study: "This study shows for the first time that a non-human brain can distinguish between two languages. This is interesting because it shows that the ability to learn to understand a language is not unique to humans.

However, we do not know whether this ability is characteristic of dogs or common among non-human breeds. In fact, it is possible that the brain may change over tens of thousands of years, meaning that the dogs that have been living with humans may have become better language listeners, but this is not necessarily the case. This will have to be determined by future studies. "

Laura Quayle added: "If you think about what it's like to be in Budapest, he's just as happy as he was in Mexico City - he saw snow for the first time and he saw it in the Danube. I love swimming. We hope that he and his friends will continue to help us in bringing about the evolution of the understanding of spoken languages. "

The study was carried out by researchers in the field of animal research at the University of Ayutthaya Lorraine and was published in Neuroimage.
