Professor Michael Beran puts on a lab coat to work with Sherman, one of Georgia State University’s three chimpanzees. The primates live in a jungle gym-like enclosure, which includes indoor and outdoor areas, at the university’s Language Research Center in south DeKalb County.

In the indoor section, Beran invites Sherman over and sets up a test using carrots and bananas; the sight of the latter makes the chimp grunt loudly. Beran covers up each food with a differently colored container and has Sherman pick which one he wants.
