![]() ![]() ![]() Fortunately, a new study on some very disciplined chimpanzees suggests that our ability to exercise restraint has much deeper evolutionary roots than our worsening smartphone addictions may suggest. Our addiction to instant gratification from our smartphones and tablets has raised red flags for many psychologists, who worry that it’s damaging our ability to appreciate delayed gratification and self-control, rendering us all impulse-driven slaves to our screens.

Supplemental Data: Working memory of numerals in chimpanzees. Current Biology, Volume 17, Issue 23, R1004 - R1005. DOI:ģ Inoue, S. On the correlation between working memory capacity and performance on intelligence tests. For this reason, the Chimp Test is also often called the Ayumu Test in honor of the chimp that beat everyone at it.ġ Verguts, T. In their study published in 2017, the researchers reported that not only did chimpanzees have a more developed working memory for numerical recollection than expected, but they also actually outperformed the human subjects.Īyumu was the chimpanzee that performed the best in these experiments, coming first among both the apes and the humans in terms of accuracy and speed. The results were then compared to those of university students who also performed the same tests as those applied to the apes. When they were proficient in recognizing not only the numbers but also their order, the researchers Sana Inoue and Tetsuro Matsuzawa conducted several experiments aimed at assessing the working memory of chimpanzees. The Chimp Test is based on one of the tests applied to Ayumu, a young chimpanzee from the Primate Research Institute at Kyoto University.Īyumu was trained from a young age, together with his siblings and mother, to learn Arabic numbers. Responses may be recorded and used for research purposes or to be otherwise distributed. We do not guarantee the accuracy of the results and these should not be used as an indicator of the capacities of the individual for a specific purpose. The results do not constitute a psychological or psychiatric evaluation of any kind and may not offer an accurate portrait of the mental fitness of the test taker. This test is designed as an entertaining and educational tool. The test will only end when you have failed a total of three sets. If you fail a set, you will repeat the exercise with the same number of digits but in different positions. ![]() The number of digits to memorize will increase as you get the sets right. You can take as long as you want to try to memorize the disposition of the numbers. The tricky part is that, once you click on the number 1, the remaining digits will turn into blank squares. The researchers concluded that “young chimpanzees have an extraordinary working memory capability for numerical recollection better than that of human adults.” 3 Instructionsįor this chimp test, you will see a set of numbers in random positions and you must click on them in order of value. 2 The chimpanzee Ayumu, in particular, outperformed humans in all aspects of the test - accuracy, and speed. Surprisingly, the accuracy was similar between apes and humans, but the first group outperformed the second when it came to the time they needed to memorize the position of the numerals. It was later also applied to university students for results comparison. The Chimp Test was specifically developed to assess the working memory of chimpanzees. The working memory is often positively linked to a higher general intelligence because it retains valuable mind sub-results that may be important when performing a task 1, regardless of its nature. This type of memory is in charge of storing small amounts of information for a short span of time to be used in the immediate or very soon. The test was designed to assess the working memory of numerals. This is a light entertainment test inspired by the one the researchers Sana Inoue and Tetsuro Matsuzawa applied to a group of chimpanzees at the Primate Research Institute at Kyoto University.
