Bonobos can tell when they know something you don’t

Bonobos is fast to a person who does not know what he knows, a sign that the mental state of others can conclude.

The ability to think about others thinking, is known Theory of mindIt is a key skill that allows humans to navigate their social world. It allows us to recognize someone that someone can have different beliefs or perspectives, to exclude our ability to understand and support others.

Our closest experience is the question of the theory of mind as well discussed for decades. Although some Mixed resultsHowever, large non-human vultures seem to have certain aspects of this capacity, suggesting that it is a greater way of thinking. For example, the wild chimpanzees that see a snake nearby, even if they are false Alert team members They know they didn’t see it.

But the primary is missing clear evidence of controlled implementation that can follow the view that is different on their own. Luke Towdow Johnland’s Johns Hopkins University.

To research this, the municipality and Christopher KrupenyeHe has also tested Johns Hopkins University by three male bonobos at the Iowa APE initiative research center.

There were three plastic glasses on a table between the Bonobo and Experimenter. A second researcher put an obstacle between the experimenter and the glass, and then he hid a gift, like a juicy grapes, under one of them.

In a version of the experiment, the “Knowledge condition”, a window of the fence allowed him to see the experimenter where he was placed. “In a state of ignorance,” their view was completely blocked. If the experimenter found food, they would give him to the bonob, offering motivation to share what the mice learned.

Towdow and Krupenye saw whether he pointed to the cup whether he pointed out how quickly, after removing 24 trials per fence.

Therefore, on average, Bonobos took 1.5 seconds to point out and pointed 20 percent more trial in a state of ignorance. “This shows that when they realize that they realize that they realize that somebody realize it has a different view,” says Krupary. Bonobos seem to understand that others understand the characteristics of what others believe that researchers have not historically understood.

This simple but strong study gives experimental support to the discoveries of wild attempts Zanna clay Durham University, United Kingdom. However, it warns that findings cannot be applied to all bonobos, because he raised learning animals in environmental environments. However, no results can be damaged to show that there is, he added.

In fact, finding this capacity in these three bonobo indicates that it exists within potential biology, and therefore, the biology of our ordinary ancestor, as also Krupenye says.

“Our ancient human relatives suggests that they can also have these skills and use each other to strengthen cooperation and coordination,” he says Laura Lewis At the University of California, Berkeley. “Understanding, when someone can be ignorant, it is a billable information like food location, our ancestors could use these abilities to communicate and coordinate more efficiently with their social partners.”
