In the journal Science, Princeton neuroscientist Asif Ghazanfar and his colleagues report that their findings contradict a long-held assumption in animal behavior.

ASIF GHAZANFAR (Princeton University):

It was generally thought that when primates are born that they’re already able to produce all of the vocalizations that they’re going to need for the rest of their lives; that there’s no involvement of experience.

HIRSHON:

Ghazanfar says the youngsters who received the most vocal feedback from their parents developed their calls the fastest, and that the species could make a good model for understanding early vocal development in humans. I’m Bob Hirshon, for AAAS, the science society.
