Chimps Outscore College Students on Memory Test 271
AP's Malcolm Ritter reports that young chimpanzees were better at remembering a series of numbers flashed on a screen, than the Japanese college students used as a control group. Scientists plan to repeat the experiment using 5th graders against the great apes.

oops? the age groups are not on equal ground. try the same thing with humans and you might just see the same thing occur. it would be amazing if the chimps' ages were more representative of those they were competing against eg. older chimps vs. corespondingly older humans, young chimps vs. young huamns

For example animals which feed by catching fast moving bugs in their mouth (eg. birds and fish) need to respond very quickly otherwise their food is long gone. Animals that eat berries and kill their food or have paws and hands don't have to be that fast. Animals that live in trees etc and need to judge distance better (monkeys etc) need faster responses than ground based humans etc.
I forget what this effect is called, but I understand that trout have a speed 20x that of humans. That's to be expected when a trout has to feed by eating little bugs coming past it in fast moving water. The trout has to be able to respond quickly to make an energy efficient movement and get the bug before it has gone. The energy in a small gnat is not enough to waste on charging around the stream.
As a result of this, I'm not at all suprised that a chimp beats a human in a low level counting game.

In fact, now that I think about it, I know lots of people whose brains function at a much lower level than a chimp...

As for why this kind of makes sense, if I were to hypothesize on it, I'd say it's probably because we ARE more intelligent that we don't perform as well with the briefer views. There's a good deal of abstract thought going on in how we deal with the numbers and different people deal with them differently. It's this ability of more and deeper abstract thought that's displacing our ability to simply see the whole thing as a single picture, but a collection of items.
On the other hand, I suspect the chimps are simply seeing a picture and recreating that picture with the tools provided. The picture holds no real meaning to them. There's no indication that the chimps understand what the digits mean. They wouldn't know 3 apples from 4 apples in terms of the digits. But human subjects, on the other hand, assign meaning to those numbers. Patterns might grab our attention. If in the digits, for example, I saw 68 in the series, it might bring to mind the year of my birth and that might distract my attention from memorizing the other digits in the number. A chimp, on the other hand, won't see the digits "02" and think, "Hey, that was the year of my birth."
And that's not to say animals don't know the concept of numbers. They do, or at least some do. There have certainly been studies to show that dogs can count up to about 5 or so (maybe it was higher) with quite a bit of accuracy, and not as something their taught, but simply intuitively... But I digress. I think the results make a lot of sense. Even though my description is probably not specifically what's going on, I wouldn't be surprised if it were something along those lines. Sure, it may make us less efficient at some simple tasks, but what's more valuable? Being able to accurately remember the order of the digits or to know what they mean?
