Look at the chart below and say the COLOUR of the word,
not the word itself.
Why is it so difficult? Because the right half of your brain
is trying to say the color, while the left side of your brain
is trying to say the word.

How many Fs do you see in the text below?
FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTIF-
IC STUDY COMBINED WITH THE
EXPERIENCE OF YEARS.
After you counted the Fs, scroll down...
How many did you count? 3?
Wrong, there were 6. Don't believe it?
Scroll back up and check. Or scroll down
for the solution...
Our brains are trained to overlook the word OF.
If you saw all 6 Fs right away, you're a genius.
Most people see only 3 Fs. Some people see 4.

amazing I only saw 3 *&(

Me too !, I did the first one OK , but not the Fs :o

Stare at the grey dot in the centre of the circles.
Now move your head forward and backward.
As your head moves closer to your monitor
and then back away from your monitor, the circles
will appear to be moving.

Take the classic visual illusion called the Müller-Lyer illusion - the one with two lines of equal length, where line "a" appears shorter than line "b" simply because of the way the arrows on their ends are oriented (see diagram). Way back in the early 1960s, psychologist Marshall Segall at the University of Iowa in Iowa City led a team testing the susceptibility of people from different cultures to this illusion. They manipulated the length of the two lines until observers judged that they were the same, then recorded this point of subjective equality (PSE) - the extent to which "a" had to be made longer than "b" for the two to be judged equal.
PSE is a measure of the strength of the illusion, and Segall found that students in Evanston, Illinois, were by far the most affected, requiring "a" to be almost 20 per cent longer than "b" before they judged the two equal. The PSE for the aboriginal San people of the Kalahari desert, at the other end of the spectrum, was close to zero. The illusion wasn't even an illusion for them.
This finding is not as trivial as it might at first appear. It implies that a fundamental aspect of perception, which had till then been assumed to be hard-wired and therefore common to everyone, is actually shaped during our development by some aspect of the culture in which we live. Though we are far from understanding this effect, Segall and colleagues suggested a possible explanation: people who grow up among carpentered corners - WEIRD people, for example - might be tuned by the geometry of their world to render them more susceptible to the illusion.
So, if you are WEIRD, you perceive the world oddly. You also have a funny way of describing it. English, the lingua franca of the WEIRD world, relies on a system for locating objects that is egocentric or relative to self, as do other Indo-European languages. So an English speaker might say: "The police officer is to the left of my car". It was assumed for a long time that this was true of all languages - but then exceptions began to crop up. These usually entailed an allocentric frame of reference, describing the location of objects relative to points outside the self, such as the points of the compass ("The police officer is west of the car") or some other object ("The police officer is between the car and the kerb").

One key factor underpinning morality is fairness. What is considered fair was long thought to be a universal human trait, but Henrich, working with a team of anthropologists and economists, has shown otherwise. The researchers looked for cross-cultural differences in people's sense of fairness using a game in which one person offers a percentage of a known sum of money to another, anonymously, on the condition that if the second person accepts the offer they both keep their respective shares, but if the second person rejects it neither of them gets anything.
The team found huge differences in behaviour. Strikingly, WEIRD people tended to make the largest offers - around 50 per cent - and when WEIRD folk were in the receiver's position, they were most likely to punish low offers with an outright rejection. People from small-scale societies make lower offers and are less likely to punish low offers from others. In other words, it was the people from the small-scale societies who adopted the more rational approach: this was free money, after all

just had this sent to me, I could do it quite quickly D) I know that the first part Yorkie did some time ago, but it still works!
If you can raed this, you have a sgtrane mnid, too.
Can you raed this? Olny 55 plepoe out of 100 can. I cdnuolt blveiee that I cluod aulaclty uesdnatnrd what I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it dseno't mtaetr in what oerdr the ltteres in a word are, the olny iproamtnt tihng is that the frsit and last ltteer be in the rghit pclae. The rset can be a taotl mses and you can still raed it whotuit a pboerlm. This is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the word as a wlohe. Azanmig huh? Yaeh and I awlyas tghuhot slpeling was ipmorantt! If you can raed this forwrad it
FORWARD ONLY IF YOU CAN READ IT
Forward it & put 'YES' in the Subject Line
Even if you are not old, you will find this interesting...

3 - Now find the N below. It's a little more difficult.
MMMMMMMMMMMMMMMMMMMMMMMMMMMMNMM
MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM

This is NOT a joke. If you were able to pass these 3 tests, you can cancel your annual visit to your neurologist. Your brain is great and you're far from having a close relationship with Alzheimer.
Congratulations!

That test is affected to a small degree by the font you force. I always force Bookman, which is a serif font, but a sans serif font would make that last test very tricky, I'm guessing.
-
It is really a matter of looking for the exception. e.g. on the N test don't look for the N, look for a missing right hand slope / . Look for a missing curve on the C ) and look for the bottom loop on the 6. ZXZ

Not a problem seen the first one before & my typing is like that most of the time anyway, if I don't cnoctratete or I try to type too qkcluiy.
The others needed my specs but quite easy . 8)

An old trick, but scientists still have no real idea what happens or why it works...

New Scientist is having a 'Weird' week. The images above, and several other fascinating illusions, are here:

You might have to register before viewing them, but it's a comparatively painless and free experience.

can't see it, or is that the illusion L0L

Must be very difficult to get the perspective just right on those.

They are amazing pics. Hubbie was saying when he went to Silverstone last year a fella called Ian Cooke did this painting of Lewis Hamilton using remote control cars.

I can't see Lewis using any remote control cars in the painting.
Are they hidden in his shorts?

One day I was sent to school in one of my Sister's old dresses, and the Teacher had on exactly the same dress. He wasn't too pleased I can tell you! L0L

I'm seeing a slight pulse, is that it or should the bow tie revolve? :laugh:
