at&t are apple's naughty friend, we should stop them seeing each other. what a nasty company.

that article doesn't seem to say anything, it seems more "freak-show headline" than brief introduction.

for a thoughtful insight into Capgras turn to the neurologist Vilayanur Ramachandran... Yes, neurologist; Capgras would seem to be explained better through neurology and when you start thinking about most headline grabbing 'mental conditions' you'll find that neurology holds the key most of the time.

What we suggest is that maybe what's gone wrong is that the fusiform gyrus and all the visual areas are completely normal in this patient. That's why when he looks at his mother, he says "oh yeah, it looks like my mother", but the wire, to put it crudely, the wire that goes from the amygdala to the limbic system, to the emotional centres, is cut by the accident. So he looks at his mother and he says - "hey, it looks just like my mother, but if it's my mother why is it I don't experience this warm glow of affection (or terror, as the case may be)...

Rama's 2003 BBC Reith lectures (available to download from the BBC Radio 4 website) are a great introduction to many wonderful experiments and also theories. He takes such extraordinary and extreme conditions and (in my mind) shows how years of misdirected psychology have ignored the science, the patient even, in search of novelty and perhaps headlines.

Oliver Sacks' "manias" in 'The Man Who Mistook His Wife For A Hat' may also be of interest, btw.
