Superior chimpanzee memory

Young chimpanzees outperform human adults in a memory test. First, the chimpanzees learned to touch Arabic numerals from 1 through 9. Then, a memory test was introduced. After touching the numeral 1, the other numerals turned into white rectangles. The chimpanzees have to remember which numeral appeared in which location. We compared humans and chimpanzees in the same test. Matsuzawa et al., Current Biology 17(23), R1004-R1005. Read the paper: (11)00788-3
