Mystery of the Scrambled Words

In September 2003, the following paragraph thundered its way around the

Internet:

Aoccdrnig to rscheearch at Cmabrigde uinervtisy, it deosn’t mttaer waht
oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and
lsat ltteres are at the rghit pclae. The rset can be a tatol mses and you can
sitll raed it wouthit a porbelm. Tihs is bcuseae we do not raed ervey lteter by
itslef but the wrod as a wlohe.

Like everyone else, I remain amazed at how easy it is to read this paragraph.
It certainly is a testament to the flexibility of the human mind. But the
paragraph’s main points—that we use only the first and last letters of a word
when reading and that we read by recognizing whole words—are actually
false. Here’s why.

For one thing, the letter transformations in the paragraph are not random. If
the letters are moved any further from their original location, the words
become much more difficult to read, as we can see in the following phrase:

Anidroccg to rcraeseh at Cgdirbmae utisreviny

As for recognizing words by their shapes, the letter transformations in
misspelled words usually alter the pattern of ascending and descending
letters and thus their shapes [see figure, “Shape Shifter”]. If anything, the
scrambled paragraph suggests that word shapes are not important, because
we can still readily recognize the transformed words despite changes in their
shapes. In fact, the consensus among psychologists who study reading is
that we recognize words not by their shapes but by looking at letters within a
word in parallel.

SHAPE SHIFTER: People don’t recognize words by their

shapes. If they did, you wouldn’t be able to read a
misspelled word, which has a different shape from its
correct form.

A literate adult reads at such a fast pace that it may seem as if the

misspelled words have no effect. It only takes a couple of hundred
