I remember reading about something like this. It was the findings of a study at a British university and as long as the first and last letter is in the right order then we should be able to read it. Its used in some train station advertisements in the UK.
For what it's worth, I'm a "righty" by nature, but found out when my right arm was in a cast that I could write with my left hand, except everything was backwards. Whatever I wrote had to be held up to a mirror. My kids loved it, but it's not something I'd want to do every day!
I've always been able to read things that are upside down too. Thought everybody could do it, but apparently not.
The original FoxNews article was probably playing on this idea that's been going around since 2003:
"Aoccdrnig to a rscheearch at an Elingsh uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht frist and lsat ltteer is at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae we do not raed ervey lteter by it slef but the wrod as a wlohe."
As long as you aren't aphasiac in any way, you should be able to read the entire paragraph without any difficultly. I spent a whole semester in college studying the idea of visual linguistics, it's fascinating stuff what the brain can do with the written word while reading.
