Talk to your dogs: Their brains process speech the same way yours does

There’s a reason that you talk to dogs like they understand: They kinda do. Dogs’ brains process speech just like human brains do.

Researchers in Hungary put a dozen very cooperative golden retrievers, border collies, and a German shepherd in an fMRI machine, and murmured praise and unknown words (“such,” “as if,” “yet”) in varying intonations. They found that the dogs’ brains responded to speech just like a human brain would, processing emotional meaning separately from word meaning.
