Scientists have taught a chimpanzee to play a child’s game

Ученые научили шимпанзе играть в детскую игруChimpanzees learned to play the game “stone-scissors-paper”

As shown in the experiment that are available to primates, the level of expertise roughly equivalent to the level of four children.

Remember the well-known children’s game? Children a little older to play, but often used as quick analog rhymes. In game two charms. First, she did not require any equipment, it is sufficient to have one free hand. Secondly, appearing in her imaginary objects are “stronger” than each other in a circle: the scissors blades about the stone that is wrapped in paper, and the paper is cut with scissors. To master this “loopback” connection, it takes a certain level of logical thinking. Whether our closest relatives can it be achieved?

Scientists from Kyoto University (Japan) has decided to clarify this issue in practice. The details of the experiment can be found in the article the authors published in the journal Primates.

The experiment involved seven chimpanzees of different age and sex living in the Research Institute of the primates at Kyoto University. Subjects sat in booths with touch screen and learn to choose the strongest of the two game variants that they saw on the screen. First, they learned a version of “paper-stone” and “stone-scissors” and, finally, the remaining version of “scissors-paper” closing the logical circle. Once the trainees have mastered this human wisdom, they were asked to choose the winner of the plurality of random options.

Five of the seven chimpanzees completed the training after 307 sessions, and two much later. It is noteworthy that the development of a third option (“scissors-paper”) took longer than the first two. When adding it, the concept loses its linearity is a strong option winner is a previous winner — and it becomes circular.

Then the same training, the same procedure was subjected to human children aged three to six years, selected in kindergarten city Sincanl China’s Henan province. History is silent, how is it that children under six years were not yet familiar with the game, but their success was clearly superior to the monkey — children (they were 38: 17 girls and 21 boys) took an average of five sessions to master the simple rules. The participants from the four years he played was obviously quite deliberately, this suggests that at this age a person has the ability to “wrap” underlying the process of logical design.

Exhibition match children against the monkeys promised to be very entertaining, but the experimenters were not included, they are still engaged in science, and for scientific purposes received enough material so. It turned out that chimps can learn some simple human fun and the underlying logic about the level of four-year-old, though more slowly.Go to the Main page
