We all know that dogs can learn to respond to human words, but it’s not always clear what’s happening in a dog’s brain when they hear and recognize words like “cookie” and “fetch.” Do they have to rely on other clues, like gestures, to figure out what we mean by that word?
Do they picture a dog biscuit when you say “cookie,” or just the sensation of eating? In a new study, scientists from Emory University and the New College of Florida tried to get to the bottom of this question by training dogs to associate certain objects with words like “blue” and “duck,” then using fMRI brain scanners to see what was happening in the dogs’ heads when they heard that word.
Science daily says :
When some dogs hear their owners say "squirrel," they perk up, become agitated. They may even run to a window and look out of it. But what does the word mean to the dog? Does it mean, "Pay attention, something is happening?" Or does the dog actually picture a small, bushy-tailed rodent in its mind?
Frontiers in Neuroscience published one of the first studies using brain imaging to probe how our canine companions process words they have been taught to associate with objects, conducted by scientists at Emory University. The results suggest that dogs have at least a rudimentary neural representation of meaning for words they have been taught, differentiating words they have heard before from those they have not.
"Many dog owners think that their dogs know what some words mean, but there really isn't much scientific evidence to support that," says Ashley Prichard, a PhD candidate in Emory's Department of Psychology can be credited for this finding. He is first author of the study. "We wanted to get data from the dogs themselves -- not just owner reports."
