The young chimpanzees performed better in terms of speed and accuracy than both their own mothers and human adults. This is not an easy task for humans however, three out of three young chimpanzees succeeded. Upon touching the lowest number, the remaining eight numbers are masked by white squares and subjects are then required to touch the masked stimuli in ascending order of the hidden numerals. Once trained to criterion on this task, we introduced a masking task to measure working memory ability. Specifically, chimpanzees can learn to touch the Arabic numerals, 1–9, in ascending order. The most striking difference reported to date between the two species is a remarkable ability to use visual working memory in young chimpanzees, who can outperform even adult humans on certain tasks. Some of this work is conducted in the form of single-subject testing of both chimps and humans at a computer terminal, where a variety of visual memory and cognitive tests are administered.Ī 2013 paper written by Matsuzawa summarized the methodology and findings of the decades-long project: Matsuzawa and his colleagues have published numerous peer-reviewed studies based on this and similar experimental setups, and have been conducting experiments similar to the one shown in the above video since 1978. The project (named “The Ai Project” after the original chimpanzee subject), focuses on “the perceptual and cognitive capabilities of chimpanzees rather than communicative skills between humans and chimpanzees.”įor much of its existence, the primary investigator has been Dr. The video is a portion of a lecture given by professor Tetsuro Matsuzawa of Kyoto University’s Primate Research Institute at the 2013 meeting of the American Association for the Advancement of Science, or AAAS. Some people noted that animals frequently display greater loyalty and affection than people, emphasising the need for more compassion and respect for all living things.A video of a chimpanzee memorizing and quickly remembering the location of numbers on a screen has been appearing on social media since at least 2013, along with text that suggests no human is capable of performing this task: Many online users were moved by the chimpanzee’s gesture. It received more than 6.5 lakh likes and more than 7,000 comments. The video, which was posted on JC Pieri’s Instagram account, immediately gained popularity. Viewers were emotionally moved by the moment because it perfectly illustrates the simple bond between a man and an animal. The chimpanzee repeatedly dips its hands into the water and then pours water over Pieri’s palms as if thanking him for the small courtesy. Then, it cleans his hands by rubbing them together as if trying to convey that his hands got dirty due to drinking water. The chimpanzee takes water from the puddle and pours it onto Pieri’s hands. It begins to clean Pieri’s hands using the water. After drinking water three times, the chimpanzee does something that will melt your heart. It asks for assistance as JC Pieri walks past and approaches the chimpanzee without concern, and it will be hard to believe, but in the video, you can see that the chimpanzee uses both of the photographer’s hands to scoop out water from the puddle and starts drinking. A post shared by JC Pieri chimpanzee appears to be thirsty as it sits close to a water pit at the beginning of the video.
