Researchers in Hungary used MRI and EEG technology to understand how well a puppy understands human words.
A family pooch probably knows the words “sit” and “stay,” but new research suggests they might understand far more than these simple commands. Researchers already knew that a human infant, at eight months old, can figure out that a group of syllables often strung together are words, whereas ungrouped sounds are probably not. Now, in a study done at Eötvös Loránd University in Hungary, scientists found that dogs do the same thing.
“This is the first time that we show that a non-human mammal can do this,” says Mariana Boros, one of the lead authors on the study. “[Dogs] can apply the exact same computations that infants are doing to segment the speech.” Researchers sought to find exactly where in the brain this was happening with MRI tests. While the dogs sat in MRI scanners, they played speech streams either built up from words that were repeated in a pattern, or from randomized syllables of words. Two areas of the brain were associated with being able to tell the difference: a more generalist brain region, and a specialized brain region.
