According to the Global Times, citing the New York Times 18**,The latest research has found thatChimpanzees have a strong memory for faces and can even recognize "old faces" from 26 years ago.
The researchers studied 26 chimpanzees raised in Scotland, Japan and other places. They installed computers on the enclosure, displayed animal faces, and placed juice in front of the screen to attract the attention of the orangutans.
* Screenshots. When the orangutan drinks the juice, a strange and familiar face that has not been seen for many years appears on the monitor. By capturing the orangutan's eye movements with an infrared camera, the researchers found that the orangutan's gaze was more focused on a familiar face.
Among them, a 46-year-old bonobos separated from his sister and nephew 26 years ago and traveled around the world, but he stared at his nephew's face for a long time during the experiment. Even after 26 years of separation, it can still recognize the "old acquaintance".
Dr. Lewis, the project leader, said that the experiment showed that chimpanzees have a limited ability to remember and cannot visualize their memories. This also means that the upper limit of the time they can remember their faces is still unknown, and they may be able to remember "old faces" for a lifetime, just like humans.
It is understood that chimpanzees are known as the "king of primate instantaneous memory", and related topics have been attracting much attention.
According to previous reports, the instantaneous memory ability of young chimpanzees is largely greater than that of adult humans, and their ability to remember complex scenes and tones in photographs with precision and detail is the ability to maintain abnormally clear and vivid images in the brain after the stimulation stops.
So, why do chimpanzees have such powerful instantaneous memory abilities?This keen memory is important for chimpanzees to survive in the wild, according to the report. Instantaneous memory helps chimpanzees often have to make quick and complex decisions in the wild: whether to forage for food between branches or deal with potential threats from other animals.
