Chimps had better working memory than humans

[Jaga]

I saw a couple of versions of the test. Chimps are able to recognize letter pattern in split of the second, the letters get hidden, chimp can still find it.... humans cannot remember the right pattern(letters from 1-10 randomly distributed on the screen that fast. I wonder whether chimps are not able to do some special maps better.....
