Feral Children!

[derrida]

Yeah, that article has a bunch of problems. Of course there have only really been two well-documented cases in the past 200 years. There was a little girl from LA in the 70's who grew up locked in a room and tied to a potty chair until she was 12. She (and in other accounts I've read the kid Vincent who inspired the truffaut movie) were considered remarkable for their relative ease versus say, a 2 year old, in acquiring vocabulary, but they never were able to develop appropriate syntax. Both of them were known to have a marked indifference to temperature (the girl preferred to draw her baths freezing cold).
