A pair of
researchers affiliated with Duke University and the Max Planck Institute for
Evolutionary Anthropology has found that great apes tend to bond with one
another when they watch a video together. In their paper published
in Proceedings of the Royal Society B, Wouter Wolf and Michael Tomasello
describe their work involving studying chimpanzees and bonobos as they watched
videos together and how they behaved afterward.
Most
people have experienced the feeling of bonding with another person, or even several
people, when watching a movie or TV show together. Until now, behavioral
scientists have believed such feelings were restricted to humans. In this new
effort, Wolf and Tomasello have shown that great apes have similar experiences.
The
experiments involved seating pairs of chimps together in front of a television
so that they could watch a video, and the researchers took measurements of
bonding-type behaviour after the video was over. They then compared the behaviour
they observed with a control group. They report that chimps that watched the
videos together engaged in more bonding-type behaviours.
