A little observation test!


How many letter F's can you spot in this sentence?
FINISHED FILES ARE THE
RESULT OF YEARS OF SCIENTIFIC
STUDY COMBINED WITH THE
EXPERIENCE OF YEARS

I thought there were three!

Or half a dozen.
Try scanning the lines of text right to left as well as reading left to right.

Re: A little observation test!

That's weird I consistently got 6 reading normally but only 5 scanning backwards even though I knew there were 6 Undecided

Re: A little observation test!

Many people see only three, apparently because the brain doesn't process link-words (like OF) that are between subject-words (like YEARS and SCIENTIFIC) in the same way, so they get missed. Six is correct, but I had to study it to be sure. Reading backwards worked every time for me!  Huh

Knowing that you were asking a trick question made me check more carefully than usual.

Yup, worked on me - I saw 3 and couldn't see them in the 'OF' words at all. Thats a great trick!

Re: A little observation test!

On first scan 3. Having seen something similar before I remembered about the "of"s and retried a couple of times and came up with 5 each time. I think that it was the two "of"s in the same line that tricked me.
