According to a study in America it seems that numeracy is not a purely human prerogative, so that the monkeys do not do too bad with math. Two neuroscientists at Duke University, Elizabeth Brannon and Jessica Cantlon, have published the results of their research on "PLoS Biology.
The study showed that these animals were able to perform tasks in mind, specifically additions, similar to the experiment umani.Durante students and monkeys were engaged in tests of arithmetic to the computer: it was necessary to add the values \u200b\u200bof two series of dots and then choose between two options, one of which carried the arithmetic sum of the two sets of addizionare.Gli results showed a 94% correct answers by students compared with 64% of the Apes: a fairly small difference, which also shows how both have fallen in the same traps.
Jessica Cantlon said: "We knew that animals can recognize quantities, but there was no evidence of their ability to perform mathematical operations like addition. Our study shows that monkeys can do it instead. "
The scientists concluded by asserting that the discovery of a common cognitive system for nonverbal arithmetic shows a kind of evolutionary relationship between their cognitive abilities.
