A scholarly article that debunks the popular Internet myth shown below:

"I cdnuolt blveiee taht I cluod aulaclty uesdnatnrd waht I was rdnieag. The phaonmneal pweor of the hmuan mnid Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer inwaht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it wouthit a porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.

This has been circulating on the Internet for years, but no such study was ever conducted at Cambridge University.
