Chimpanzees Take Turns in Fast-Paced Conversations, Just Like Humans Do

A new study finds the average chimpanzee response time in gestured conversations is 120 milliseconds, which isn’t that far from the human average of 200 milliseconds

When humans have conversations, we take turns speaking, sometimes even interrupting each other. Now, a study published in Current Biology on Monday reports that chimpanzees follow a similar communication pattern structured around back-and-forth, fast-paced turns—albeit with gestures rather than speaking.

“Human conversation follows very strict rules of turn-taking that are consistent across cultures and languages,” Gal Badihi, an animal behavior researcher at the University of St Andrews in Scotland and first author of the study, tells the Guardian’s Tanya Procyshyn. “We started to wonder whether chimpanzee communication was governed by its own rules, or if the rules are similar to human conversation.”

Chimpanzee gestures are largely meant to convey requests, with “groom me,” “follow me,” “give me” or “stop it” being common commands. The researchers witnessed a variety of gestured interactions, such as chimps asking to change spots during grooming sessions. Once, a chimp named Ursus gave a reassuring tap to a chimp named Monica when she reached her hand out after a quarrel. In another instance, a male chimp repeatedly made “go away” gestures as a female asked for some meat from an antelope he had killed.

To explore patterns in this communication, the team of scientists collected footage of 8,559 gestures from 252 individuals in five chimp communities in eastern Africa, assembling the largest dataset of chimpanzee conversations ever made. They found that 14 percent of the recorded interactions included at least one response to a gesture, while some included as many as seven back-and-forth responses.

I was always interested in how animals communicate with each other. I observed it in my cats at home. How they touched noses to greet, how they invited each other to play, etc. One of my cats went blind. We didn't realize at first. His litter mate had started meowing at him to play or to get him to cuddle with him on the cat beds. Cats don't usually meow at each other. We didn't know that. They were always together, too. Where Osie went, his litter mate followed. A little while later we noticed Osie, our kitty that went blind, had started bumping into things. We took Osie to the vet, who sent us immediately to an Ophthalmologist for cats. He told us Osie had untreated high blood pressure that caused him to go blind. His blood pressure was treated and Osie regained some of his sight, but mostly just movement and shadows. While Osie got along fine finding his own way in the house, Seb, his litter mate, continued to meow at him to help Osie find his way. All of this story was to say if we had known that it was unusual for cats to meow at each other we might have asked the vet what was going on earlier. Osie might have been treated sooner for high blood pressure and kept more of his sight. We'll never know, of course, but so glad scientists are researching how animals communicate with each other. Maybe we can really "talk to the animals" some day! I really enjoyed this article. Thank you!
