Researchers said it shows brain activity for this comprehension in a non-human animal for the first time
although other experts have questioned the study's conclusion.
It is well known that dogs can learn orders like “sit,” “stay,” and “fetch” and respond to them
with learned behaviors, typically with treats, but understanding nouns has been more difficult.
The study's principal authors had 18 dog owners say terms for objects their canines previously knew.
Electroencephalography (EEG) was performed on dogs with small metal discs harmlessly
affixed to their skulls while the owners held up the matched object or a different one.
