koko is indeed QI.
Indeed, and "on the scale of humans". I've sufficiently shown your error.
Sadly, you felt the need to both quote mine and not provide the source, which is not the kind of behaviour I expected of you - i came here to discuss and learn not point score at all costs. However, I'm an atheist and a rationalist so I am capable of true forgiveness.
Here's the full paragraph
Message 83. Full paragraph and source provided. I shortened it because I was repeating it.
So Koko has been intensively trained since near birth and for 40 years by a very dedicated team of people and has learned around 2000 signs. She's been rewarded when she she gets it right and as a result has apparently achieved the language IQ level of a sub-normal human.
Unfortuantely, the team 'publish' most of their findings via the mass media - there are a few peer reviewed papers but I haven't seen any. I do know that there is a lot of controversy surrounding what she actually understands and what she's merely been conditioned respond to.
However, I did see a documentary on Koko a couple of years and I was very impressed; from watching it I'd say that she definately understood some things and is fairly obviously not clueless.
But really, she's not even on the same page as us. Not even close.
Translation: "yeah, you're right. But I'm gonna keep making my same false claim."
And its funny that you're nitpicking the fact that Koko was trained while failing to account for the fact that humans can't invent the technology you herald them for having without their own training.
