MEIXD UP

So  the following was posted on Facebook and I thought it was pretty interesting, since it wasn't until the explanation that I gave much thought to the process my brain was using to read the text:

AOCDRNDICG TO RSCHEEARCH AT CMABRIGDE UINERVTISY, IT DSENO'T MTAETR WAHT OERDR THE LTTERES IN A WROD ARE, THE OLNY IPROAMTNT TIHNG IS TAHT THE FRSIT AND LSAT LTTEER BE IN THE RGHIT PCLAE. TIHS IS BCUSEAE THE HUAMN MNID DEOS NOT RAED ERVEY LTETER BY ISTLEF, BUT THE WROD AS A WLOHE. IF YOU CAN RAED TIHS, PSOT IT TO YUOR WLAL. OLNY 55% OF PLEPOE CAN :)

 Now there's a couple questions I have. I know what they say about thinking in words, not letters, is true from my days learning ASL sign language. Reading fingerspelling was very difficult since our beginner brains were still mentally translating every letter. The teacher told us to try and "read" the whole word instead of the letters. I think if she had told us to grab the first and last letters and use our gut for the middle it would've been easier.

So now my analytical brain starts picking apart the post itself. If the human brain reads the word as a whole, why can only 55% of people read the above paragraph? I have to assume everyone was a native English speaker. And does a dyslexic person have an advantage since their letters are mixed up all the time? Does the writing have to be in capital letters?  Wlel, I sopuspe taht one is esay to tset. Tihs guy wklas itno a psiachyrtsit's oicffe wtih a dcuk on his haed. the psiachryrtsit syas can i hlep you? and the dcuk syas yaeh get tihs guy off my ass. 

Another thought is that they didn't do a great job scrambling the letters. They have whole chunks intact :

RSCHEEARCH vs. RCSEEHRACAH - one is a whole lot easier to understand. I think it would be interesting to see the difference between 100% scrambled and phoneme-scrambled. In the end though, it's pretty cool your brain can sort it out with only a small delay in comprehension.
