O Povo TsimaneThose who live in the remote forests of Bolivia, in the opinion of scientists, often do research because they are offered by the people who wrote them. The healthiest hearts in the world. Residents recently participated in a new academic study, which allows them to evaluate the importance of numbers in their lives and to guess how this can vary depending on how much each person can count. But let us go in order and try to understand what it means.

Refers to research by the Massachusetts Institute of Technology and the University of California The relationship between the ability to count individuals and the success of completing tasks The enumeration numbers were assumed to be approximately 25. Researchers have found that most people can accurately perform tasks that require object matching, but only to the highest number they can estimate.

The result suggests that people must have a word for that number to represent a particular quantity greater than four, says Edward Gibson, professor of cognitive and brain science. “This finding gives us the clearest evidence that the number translated into words plays a role. Functional role in people’s ability to represent small quantities Larger than four, it supports the broader concept that words allow for new conceptual abilities. “

Another study in 2014 explained that children learn the meaning of words that translate numbers just like children in countries and villages learn Simon. Industrial communities. That is, they learn first.one two Three‘, in order. From there there is a radical change in the understanding and understanding of the meanings. “Five” In this “Six”, But for all the other numerical terms they know.

In industrial societies where numbers are of great importance, children learn to count by the age of two and develop complex comprehension by the age of four or five. However, Simon has no children The way is differentHe continues to study, beginning at the age of about five and ending at eight.

In this new study, researchers identified 15 simans who could count between six and 20, as well as another 15 who could count to at least 40. This allowed scientists to compare the two groups with different enumeration capabilities. . People can make it without numerical representations Perform tasks Ask them to create a file Psychological representation of more than four numbers.

For this, a task called research team was used orthogonal congruence. In the simplest step, the researchers presented a series of objects, such as batteries, and then asked participants to arrange an equal number of different objects, such as thread spools. With orthogonal matching, the objects are shown in a horizontal line, but participants must align the corresponding number vertically so that they do not match one by one.

The result

The MIT team found that Simon was able to get people to complete this mission, but to a lesser extent than they could have imagined. That is, those who can count to 10 will start to lose when asked to hit eight or nine items, while those who can count to 15 will start missing 13 or 14.

The results indicate that the file Tasks that require number crunching can only be done using number words Or other explicit numerical representation systems.
