Chimps beat humans in memory test.

The discover was made in Japanese. Researcher Tetsuro Matsuzawa and other colleagues of Kyoto University made the experiments with three pairs of mother and baby chimpanzees and university students. Every one of experiment subject was presented with various numerals from one to nine on a touch screen monitor. The numbers were then replaced with blank squares. The test subject had to remember which number appeared in which location, then touch the appropriate square. In a result chimps performed much better than university students in speed and accuracy. Young chimps have a photographic memory which allows them to memorise a complex scene or pattern at a glance.
