"aiming to produce a machine that can see and interpret as well as a human."
First I want to say that this whole level of brain modeling is really cool. However, there are, of course, different levels of "interpretation" I don't think that this computer will be able to achieve a human level of interpretation simply by modeling the visual cortex.
perception: at one level you could argue (not very effectively) that interpretation just means perception... that's an eyeball/optic nerve visual cortex thing. e.g. You can perceive a face.
recognition/categorization: of visual forms involves the visual cortex/occipital lobe. e.g. you can recognize if that face is familiar
interpretation: involves assigning meaning to a stimulus and this involves many more parts of the brain than the visual cortex. It's obviously tied to memory which is closely tied, physiologically, to emotion. It also involves higher order thinking since, when most humans interpret a real world stimulus, there are multiple overlapping and networked associations that must be processed into a meaningful whole. e.g. you can recognize how threatening that face is, why it is threatening or not (and in what substantive domains it is or is not threatening), and even what you should do about it.
Even "interpretation" at the second level above (which it seems the "roadrunner" might be able to model) require a lot more, for humans, than just the visual cortex.
In other words if we were to call into existence a floating occipital lobe connected to a couple of eyes that had never been attached to the rest of a brain we would never be able to achieve recognition/categorization let alone interpretation. If I'm wrong maybe some of you hardcore neuroscience type can help me out?
Whoever wrote this "IQ" test is apparently not smart enough to understand how an IQ test works.
You can debate whether a real IQ test measures anything other than the ability to do well on IQ tests, however, real IQ tests don't depend on real world knowledge. It appears that many people on/. apparently don't actually how an IQ test works. The most common, authentic, IQ test, the WAIS (http://en.wikipedia.org/wiki/Wechsler_Adult_Intelligence_Scale) is used by psychometrecians to assess the "The global capacity of a person to act purposefully, to think rationally, and to deal effectively with his/her environment."
We use it in my clinical training program to do neuropsychological assessment and cultural/historical information is certainly relevant to dealing effectively with one's environment...
now a more interesting question (in the last 20 or so years) comes up here about IQ test bias. Which types of people, demographically, are the ones who get to decide what is the most relevant cultural information to have? Which types of people, demographically, are most likely to obtain lows scores on these indices?
