Is this a strong-mind test or a weak-mind test?  One might assume that a
stronger mind would "see the world as it really is" or something like that. One
might similarly assume that a weak mind would be "fooled" by something like
this. The message claims that it is an impressive human achievement to be able
to see a 5 as an S and a 1 as an I. I'm not convinced. 

My guess is that if I trained a rat to press one lever when it saw an S, and
another lever when it saw an E you would not think that was very impressive.
What if I then showed the rat a five, and it pressed the S lever, and I showed
the rat a three and it pressed the E lever? My guess is that you would still
not find this very impressive, that it would not be evidence that that rat has
an amazingly "strong" mind. I'm also pretty confident that I could get gold
fish to show the same effect.

P.S. Eleanor Gibson, wife of James J. Gibson, the perceptual psychologist who
has come up in a few conversations, was one of the most prominent developmental
psychologists of the past decade, and won the National Medal of Science. Though
she is best known to the public for the "visual cliff" experiments that often
get a nod in intro psych textbooks, for more than a decade she studied reading.
One of the major finding was that skilled readers use form perception to read,
with minor sensitivity to the initial and final letters - that is, in the
course of normal reading, skilled readers do not identifying all the letters in
the word, they don't have to. The reason that the image below seems mysterious
is that we have been told over and over again by our teachers that that reading
is about identifying individual letters and "mentally" forming them into
words.... but it just ain't true.
