Chimpanzees Use gestures to communicate

Researchers at Georgia State University's Language Research Center understand how two language-trained chimpanzees communicated with a human experimenter to find food.The chimpanzees used gestures to recruit the assistance of an otherwise uninformed person and to direct the person to hidden objects 10 or more meters away.

"It allows the chimpanzees to communicate information in the manner of their choosing, but also requires them to initiate and to persist in communication," Dr. Charles Menzel, a senior research scientist at the Language Research Center, said in a press statement. "The chimpanzees used gestures to recruit the assistance of an otherwise uninformed person and to direct the person to hidden objects 10 or more meters away. Because of the openness of this paradigm, the findings illustrate the high level of intentionality chimpanzees are capable of, including their use of directional gestures. This study adds to our understanding of how well chimpanzees can remember and communicate about their environment."

The human experimenter did not know where the food was hidden, and the chimpanzees used gestures like pointing to guide the experimenter to the food.
