Using machines that measure brain activity, scientists were able to show that dogs understand that words refer to some of their favorite objects.
Our dogs understand us better than they've been given credit for — and scientists say they have the brain wave evidence to prove it. By placing electrodes on the heads of 18 pet dogs, researchers found striking evidence that the animals did not merely recognize the patterns of sound that come out of their owners' mouths, they actually realized that certain words refer to specific objects. The findings were reported Friday in the journal Current Biology.
Boros and her colleagues posit that the same thing happens in the brains of dogs: After hearing their owner use the word for an object, they called it up in their mind in anticipation of seeing it. Then, when an object appeared, it was either the thing they expected or something that threw them for a loop. The reason the dogs could tell something was amiss was that they understood the spoken word.
