Chimps Really are Smarter

Think you’re smarter than a chimp? Check out this story.

Apparently, researchers in Japan wondered the same thing (probably after watching Paris Hilton interviews) and pitted the memory power of chimps against college students.

One memory test included three 5-year-old chimps who’d been taught the order of Arabic numerals 1 through 9, and a dozen human volunteers.

They saw nine numbers displayed on a computer screen. When they touched the first number, the other eight turned into white squares. The test was to touch all these squares in the order of the numbers that used to be there.

Results showed that the chimps, while no more accurate than the people, could do this faster.

One chimp, Ayumu, did the best. Researchers included him and nine college students in a second test.

This time, five numbers flashed on the screen only briefly before they were replaced by white squares. The challenge, again, was to touch these squares in the proper sequence.

When the numbers were displayed for about seven-tenths of a second, Ayumu and the college students were both able to do this correctly about 80 percent of the time.

But when the numbers were displayed for just four-tenths or two-tenths of a second, the chimp was the champ. The briefer of those times is too short to allow a look around the screen, and in those tests Ayumu still scored about 80 percent, while humans plunged to 40 percent.

Holy crap! Chimps really are smarter than the president! And here I was just making jokes because of the similarity in appearance.

There’s a logical theory for why these chimps scored better than the college kids.

What’s going on here? Even with six months of training, three students failed to catch up to the three young chimps, Matsuzawa said in an e-mail.

He thinks two factors gave his chimps the edge. For one thing, he believes human ancestors gave up much of this skill over evolutionary time to make room in the brain for gaining language abilities.

The other factor is the youth of Ayumu and his peers. The memory for images that’s needed for the tests resembles a skill found in children, but which dissipates with age. In fact, the young chimps performed better than older chimps in the new study. (Ayumu’s mom did even worse than the college students).

Ah! There ya go then.

But students had 6 months of training and still couldn’t beat the chimps. That’s funny.
