Dogs Understand Praise The Same Way We Do

by Virginia Morell: Here’s why that matters…

Awaken

Every dog owner knows that saying Good dog! in a happy, high-pitched voice will evoke a flurry of joyful tail wagging in their pet.

That made scientists curious: What exactly happens in your dog’s brain when it hears praise, and is it similar to the hierarchical way our own brain processes such acoustic information?

When a person gets a compliment, the more primitive, subcortical auditory regions first reacts to the intonation—the emotional force of spoken words. Next, the brain taps the more recently evolved auditory cortex to figure out the meaning of the words, which is learned.

In 2016, a team of scientists discovered that dogs’ brains, like those of humans, compute the intonation and meaning of a word separately—although dogs use their right brain hemisphere to do so, whereas we use our left hemisphere. Still, a mystery remained: Do their brains go through the same steps to process approval?

“It’s an important question, because dogs are a speechless species, yet they respond correctly to our words,” says Attila Andics, a neuroscientist at Eotvos Lorand University in Budapest, Hungary, and co-author of both the previous study and the new one, published this week in the journal Scientific Reports. For instance, some dogs are capable of recognizing thousands of names of individual objects, and can link each name to a specific object.

When the scientists studied scans of the brains of pet dogs, they found that theirs, like ours, process the sounds of spoken words in a hierarchical manner—analyzing first the emotional component with the older region of the brain, the subcortical regions, and then the words’ meaning with the newer part, the cortex.
