New research suggests babies as young as six months old understand more about language than was previously believed, per the Atlantic.

In the study, babies were first shown two different pictures at a time, of things like a blanket and a dog. Researchers observed what image the babies looked at after their parents named an image. The babies had a harder time distinguishing the difference between pictures of related things, like nose and mouth, than they did of the unrelated pictures. Per the Atlantic, this difficulty of distinguishing related images shows "that they somehow understand that the concepts are related."
