Earlier quoted context omitted.
By innate do you mean evolved/instinctive? Surely even evolved behaviour must be expressed as brain function, and therefore would need a brain capable of handling that level of processing. I don't think it's clear how much of a human brains function exists at birth though, I know it's theorised than even much of the sensory processing has to be learned.
I'm not arguing against computational theory of mind, I'm just saying that innate behaviours don't require the same level of scale as learnt ones. Existing at birth is not the same thing as innate. Puberty is innate but it is not present at birth.
That's an interesting point. I can see that, as you say puberty and hormones impact brain function and hence behaviour, and those are inate and not learned. But at least superfically that would appear to be primarily broad behavioural effects, similar to what might be induced by medication. Rather than something that impacts pure abstract problem solving, which I guess is what the Atari games are supposed to represent?
