     In a memory-based competition between you and a chimp (猩猩); who do you think would win? If you
put yourself on top, you might want to guess again.
     In a test that challenged participants to remember numbers, a young chimp performed better than Japanese
college students.
     Here's how the test worked. At Kyoto University in Japan, human students and chimpanzee participants
sat in front of a computer. Five numbers, ranging from 1 to 9,were combined with one another and then, they
appeared at random places on the screen.
     The numbers stayed on the screen for less than a second. In the first test, for example, participants saw
the numbers for 650 milliseconds (about two-thirds of a second).
     Then, each number disappeared and they saw a white square instead. Participants had to touch the squares
in numerical order, based on the numbers that had been there a moment before.
     In this test, the students touched the boxes in the correct order about 80 percent of the time. A young
chimp named Ayumu performed equally well.
     During a harder test, participants were only able to see the numbers for 210 milliseconds.
     This time, students only succeeded in putting the boxes in the correct order about 40 percent of the time.
But Ayumu still could select the boxes in the right order nearly 80 percent of the time.
     Some people have what's called a "photographic memory," which allows them to remember a surprising
number of details after just a quick glimpse of something. Ayumu's memory might work in a similar way, says
lead researcher Tetsuro Matsuzawa.
     The chimp's young age might have something to do with his impressive perfomance, too. In previous tests,
the Japanese researchers found that young chimps perfomed better than their mothers.
     The scientists are interested to see whether Ayumu loses his strong memory as he gmws older. They already
know that young children sometimes have sharp memories when offered something photographical, but they
lose this ability over time.
