Eye Exam

  1. Feb 11, 2004 #1
    Eye Exam...

    Try this its actually quite good.

    Please don't cheat!

    Count the number of F's in the following text:

    FINISHED FILES ARE THE
    RESULT OF YEARS OF SCIENTIFIC
    STUDY COMBINED WITH THE
    EXPERIENCE OF YEARS









    Managed it?

    Scroll down only after you have counted them!












    OK?


    How many?







    Three?









    Wrong, there are six - no joke!



    Read again!




    FINISHED FILES ARE THE
    RESULT OF YEARS OF SCIENTIFIC
    STUDY COMBINED WITH THE
    EXPERIENCE OF YEARS



    The reasoning is further down...

    The brain cannot process the word "OF".


    Incredible or what?

    Anyone who counts all six F's on the first go is a genius (yeah right:))


    Three is normal.

    So what’s your result, and how do you explain (if you saw) seeing only 3 F’s ?
    I’ve played with this “exam” long time ago and saw 4 F’s … conditions aren’t perfect you read more carefully because of title, anyway it’s fun...

    What! I don't get it, I counted six the first time.



    Na, j/k that is pretty cool. I did notice one of the of's, so I counted 4.

    Any idea why the brain does this?

    Damn! I got 5. I knew the trick, so I read it backwards. I still only got 5!

    Actually, I read somewhere that not counting the f in of is a sign that you are a good and efficient reader.

    Saying the brain can't process the word "of" is just a tad misleading. :wink: Of course it can-- otherwise you wouldn't read the word "of" to yourself when you read that text.

    I can think of two plausible reasons why this counting trick works.

    One, "of" is so small and so commonly occurring in English that the brain treats it as one incompressible unit rather than as a composite of smaller elements.

    Two, experienced readers automatically translate the visual symbols of language into internal auditory sounds, and it is the sounds of the words (not the visual impression of the words) that the reader uses to consciously access their structural and semantic content. The f in "of" is pronounced as a v sound, so if you depend on your primary means of understanding written language in order to analyze that text (as you naturally would tend to do), it will not occur to you that the word actually has an f in it.

    Knowing it was a test I paid attention, counted carefully, and got six the first time.

    I must post to boast, (since I did pretty poorly on Monique's densa test.)
