Spelling matters?

[sagehen]

The ease with which this passage can be read is by no means unambiguous
evidence that adults read by grasping the first & last letters of each
word.  The high predictability of each word, and the fact that as
experienced readers of typescript on paper & screen we are all very
accustomed to typos of various sorts and particularly inversions of groups
of letters make mental correcting automatic.
