Scientists find that dogs understand what you're saying
Scientists have found proof to support what many dog owners have long believed. Dogs really do understand some of what we're saying.
Researchers in Hungary scanned the brains of dogs. Hungary is a country in central Europe. The researchers did the scans as the dogs were listening to their trainer speaking. This was to determine which parts of the brain the pooches were using.
They found that dogs processed words with the left hemisphere of their brain. Meanwhile, tone was processed with the right hemisphere. That is just like humans.
What's more, the dogs only registered that they were being praised if the words and tone were positive. Meaningless words spoken in an encouraging voice, or meaningful words in a neutral tone, didn't have the same effect.
"Dog brains care about both what we say and how we say it," said lead researcher Attila Andics. He is a neuroscientist. He teaches at Eotvos Lorand University. It is in Budapest. That is the capital of Hungary. "Praise," Andics said, "can work as a reward only if both word meaning and intonation match."
Andics said the findings suggest that the mental ability to process language evolved earlier than previously believed. And, that what sets humans apart from other species is the invention of words.
While other species probably also have the mental ability to understand language like dogs do, their lack of interest in human speech makes it difficult to test, said Andics.
Dogs, on the other hand, have socialized with humans for thousands of years. That means they are more attentive to what people say to them and how.
The study was published in the journal Science.
Andics also noted that all of the dogs were awake, unrestrained and happy during the tests.
"They participated voluntarily," he said.
