I found out in a column in sciencenews.org that in a rapid number recollection test, college students were outsmarted by a young chimpanzee named Ayumu. In Kyoto University in Japan, this test was performed. This test involved students and chimps seeing an array of five of the numerals 1 through 9 flash onto a computer screen for just 650 milliseconds. When the numerals simultaneously turned into white squares, the subjects had to touch the squares in numerical order. The students managed to choose the squares in the correct order around 80 percent of the time, as did Ayumu. the researchers performing the test then shortened the viewing time of numerals to 430 milliseconds, then shortened more to 210 millisecond. For these viewing times, the students correctly got around 40 percent of the various sequences, but Ayumu still correctly got nearly 80 percent of the various sequences. Tetsuro Matsuzawa, one of the researchers performing the tests assumed that Ayumu's success comes from something close to the photographic memory in humans.
This article interested me because I didn't know that chimpanzees have that kind of photographic power at their disposal. After reading this article, a sudden respect for chimpanzee came into me when I watched the video provided in the article. When you watch the video, you would be surprised like I had been when I first saw it. I recommend watching the video so that you can see it for yourself.
