The eternal question for dog owners: if your favorite pet understands what he is told? Of course, many immediately replied in the affirmative, but still would like to receive and scientific evidence. And as it turned out, they are. A new study of Hungarian scientists show that dogs with brain responds to specific words, not only the tone of statements of the person.
It was already known that the pet will feel the difference between a friendly tone master and dissatisfied, for example, on the occasion of the next “accident” on the carpet. Scientists also have been interesting to see how the dog reacts precisely to specific words.
The words, the basic building blocks of human language, in the “talk” to other animal species almost never occur. Bottlenose dolphins (view dolphins) and zelenohvostye forpus create certain sounds to indicate the names of relatives. By the way, recently, scientists have found that dolphins even talk to their cubs until they are in the womb. Others animals, including chickens, prairie dogs and certain primates, emit a distinctive warning signals, which contain information about a particular predator
such skills Dogs do not have:. They do not say no “words”, but some of them detect human over 1000 words. This means that the four-legged friends a person can understand their meaning, thought Hungarian scientists.
However, any scientific assumptions should always be checked. For this reason, the researcher Attila Andiks (Attila Andics) and his colleagues at the University named Lorand Eötvös in Budapest scanned the brains of 13 dogs of four different breeds: Border Collie, Golden Retriever, Chinese Crested Dog and the German Shepherd

All the dogs were trained to lie still in the MRI -skanere while being listened to recordings of the voices of their coaches. Animals hear meaningful words (eg, “great job!”) In a positive tone in a neutral tone. In addition to the meaningful words uttered pets and meaningless words (eg, “as if”) in a neutral tone and encouraging.
Then the researchers analyzed the results of the scan. It was found that, regardless of the tone dog trainer treated meaningful words in the left hemisphere of the brain (just like humans). However, the dog did not do the same when listening to meaningless words. “Words have meaning for dogs”, – concludes Andiks
Moreover, the dogs also draw attention to the intonation -. This information is processed in the right hemisphere. Similarly, work and the human brain. And at the moment when the animals heard words of praise, said in an approving tone starts to activate another part of the brain: the pleasure center. That is the meaning of words and intonation reinforce each other
“They combined two types of information to interpret what they heard people do the same.” -. Said Andiks
Scientists thanks. new information begin to better understand how the brain processes dogs human speech. Pets have the parts of the brain that interpret the voice, the differences in sounds (in the left hemisphere) and analyze the sounds that convey emotions (the right hemisphere).
Of course, if a person has a great experience with dogs, most all this information will not be shocking for him. However, the new study provides important scientific evidence that pets really know the difference between the words “biscuit” and “well done”. It does not matter how these words were spoken.
The findings, however, “does not mean that dogs understand absolutely everything that we say,” notes Julie Hecht (Julie Hecht), which studies the behavior of dogs the City University of New York. “But our words and intonation are not for dogs meaningless,” – she adds
Some researchers want to repeat the experiment in other animals and wolves, which brought people to understand how deep the ability to understand human lies. in dogs and depends on whether it is on the animal grew among the people or not.
group Andiks The study is published in the scientific journal Science.
We add that recently “Vesti.Nauka” told what exactly makes dogs happy, and we are not talking about a favorite treat. In addition, we wrote about the fact that other people close to the animals – horses also have a particular understanding of the human
