So Ayumu is a chimp, child of Ai and they participate in the Ai project. There are several mother / child pairs that have been studied for short-term memory ability.
I’m sure lots have already seen the video of ayumu being presented with numbers in random places around a screen and then being able to press where the numbers were in sequence at blazing speeds and did it better than the mother.
But Ayumu also did it better than all the other chimps and when compared to humans, humans did the task better to the chimps, but Ayumu’s speed is outstanding and they don’t know why.
So, here’s a hot take, could Ayumu just be autistic, and excel at such tasks?
I think that article here is specifically referring to the tests where the numbers are flashed up for 240ms (or such) and then hidden.
