Young chimpanzees outperform adult chimps on working memory tasks.

Evidence

However, such excuses can go both ways. The human team was stacked with young, educated adults who were likely at their human peak of working memory and processing speed. If the chimp team had a complex communicative repertoire, like humans, they would no doubt call for a rematch against five-year-old children to match the ages of the young chimpanzees. The young chimps, who actually outperformed their mothers, would probably defeat any group of young kids. The chimps would also charge that the students had a lifetime of experience with the bizarre Arabic numerals that they were forced to learn while in captivity. — Joseph Henrich, The Secret of Our Success, 92
