Found evidence that dogs understand human language

By scanning the brains of dogs while humans are ordering them, scientists find that similar to humans, will treat words with the left hemisphere while the hemisphere must be used to handle sound height. This is evidence that dogs can really understand some of the things humans say to them.

Human speech not only stimulates processing activity in the dog's brain, but in the study, scientists also found that dogs only feel happy and praised if their words and intonations are the speaker is positive. On the contrary, even though it is a compliment, if people use meaningless words or words with neutral intonation, there is no effect to create joy for dogs.

The leader of the study, Attila Andics neurologist at Eotvos University Lorand, Hungary, said: "The dog's brain is concerned with both the content and the way we talk to them. The compliments are effective only. positive when people use appropriate words and intonation ". Andics claims that this finding shows that the ability to handle language has evolved earlier than the previous hypothesis and this is also what helps people overcome other species in the invention of language.

Dogs may be able to pay more attention to what people say and what they do.

Professor Andics stated that there may be many other species that also have the ability to understand the language like dogs, but they do not care about human speech, so it is difficult to test the test. In contrast, dogs have lived with humans for thousands of years so they can pay more attention to what people say and what they do .

In the experiment, the team used six dogs border collies, five golden retrievers, a German shepherd and a Chinese buttercup dog. All are trained to remain motionless in the scanner for 7 minutes of testing. The dogs are awake and relaxed when they hear the words of the trainer via headphones. Andics said: "The most difficult aspect of this training is to teach the dog to lie still meaning really immobile."

The results of the study may not be surprising to those who own dogs but from a scientific perspective, the discovery of dogs using the left hemisphere of the brain to process words is a shocking finding. However, the neurologist Gregory Berns at Emory University points out that this research is based on a small group of dogs, so before the final conclusion is reached, more research should be conducted on a sample size large enough to Find more evidence of the dog's brain activity to prove that they really "understand" people.
