On some intelligence tests, chimps beat humans.

I posit that a chimp could understand and learn from Wikipedia if it were presented audiovisually (like Qwiki.com but with the English speech replaced by a much simpler (sign?) language).<p>And what if the chimp were also wearing Transcranial Direct Current Stimulation?

Does anyone have the link to the original article (or title or authors)? It looks interesting, but this version has almost not details.
