It turned out that monkeys fully understand the concept of "number" and can also add up

"If you only reflect on monkeys you can do itIt is well known that a monkey has advanced intelligence like a phrase prevalent, but by the research of the latest brain scientists, the fact that "if only addition can be done with a monkey" has been discovered.

Symbol addition by monkeys provided evidence for normalized quantity coding

The research team of Dr. Margaret Livingstone of Harvard University's brain science researcher discovered that it is possible not only to judge the magnitude of numbers after teaching numbers to rhesus monkeys but also to add up. In this research,Presented at the National Academy of Sciences bulletin (PNAS)It is being done.

In the experiment, first, let the monkey remember cards with signs (symbols) corresponding to numbers from 0 to 25. After that, I repeated the training of showing two cards and giving food only when I chose a large number of cards. Then, the monkey gradually understanding the number not only became able to understand by simply understanding the magnitude of the two numbers,It was possible to judge up to the size by adding the numberAnd that.

The picture below was taken during the experiment. Monkeys chose cards written "4" and "5" instead of "8" cards. In other words, the monkey is correctly calculated to be 4 + 5 = 9 larger than 8.


So farResearch results that monkeys can addAlthough it was announced, there was an indication that the monkey might not simply calculate it simply by remembering the card as "form". So, after checking that monkeys can remember and calculate numbers from 0 to 25, Dr. Livingstone again taught again different symbols from 0 to 25, and the monkey was drawn with a new sign I found that cards can be calculated correctly immediately. In other words, it was confirmed in this experiment that monkeys did not memorize cards by heart, but understood the concept of numbers.

According to the study presented this time, it was confirmed for the first time that monkeys can comprehend the concept of numbers and add them up, not depending on memory, but if you look at the following movie, "Monkey's It may not be so surprising to discover the advanced intelligence you have.

A monkey that folds branches of trees.


this isBonoboIt is a monkey belonging to the family department with chimpanzees.


Bonobo bent off a branch.


I take a breath and wipe the sweat of my forehead.


Fold the thick branches well with your knees.


Together they will throw the branches and throw them, and stack firewood.


It was the match box that I picked up in a hurry.


Tap on the box with a tapping hand and take out the match from inside ... ...


I rubbed a shot ......


I put out the fire brilliantly.


Bonobo who ignites firewood using a match is this doya face.


Put a branch in the flame, ascertain the degree of fire ... ...


I inserted a marshmallow in the tree branch.


After watching the marshmallow skewers ... ...


I will give it to a fire.


Completion of baked marshmallows.


Whether or not you are murmuring "Marshmallow is limited to baking!" Is not certain, but Bonobo brings her mouth close to baked marshmallow ... ...


Unexpectedly "hot !!"


After being fluffy ......


Pakuri. I ate a marshmallow roast.


In addition, Bonobo seems to be able to play "Pac-Man" well.
