Freaky Optical Illusion! Answered

Here is a cool optical illusion I got in an email:

'The Brain'

This is quite amazing..

If you see this lady turning in clockwise you are using your right brain.
If you see it the other way, you are using left brain.
Some people do see both ways, but most people see it only one way.

See if you can make her go one way and then the other by
shifting the brain's current.

Experimentation has shown that the two different sides, or hemispheres,
of the brain are responsible for different manners of thinking.
The following table illustrates the differences between left-brain and
right-brain thinking:

Left Brain Right Brain

Logical Random
Sequential Intuitive
Rational Holistic
Analytical Synthesizing
Objective Subjective
Looks at Looks at
parts wholes

Most individuals have a distinct preference for one of
these styles of thinking. Some, however, are more
whole-brained and equally adept at both modes.
In general, schools tend to favor left-brain modes of
thinking, while downplaying the right-brain activities.
Left-brain scholastic subjects focus on logical thinking,
analysis, and accuracy. Right-brained subjects, on the
other hand, focus on aesthetics, feeling, and creativity.

If you look away, she may switch from one direction to the other.

I found that if I just look at her feet or relax and look at the floor
where the reflection shows, she will switch direction!


i think that this just made so every once in a while it switches directions

Oh that is odd I kinda got these time when it would judder and change direction or kinda go back and forth...

I agree, it is not a smooth circular motion, so observing that, it makes it quite easy to make it change direction or even see it swing back and forth. But then, I have an odd way of perceiving things at times. . . especially optical illusions

Eh it's a simple enough illusion, I checked out the propertes and gues that there are two counter rotating people going back and forth, the brain percieves it's preffered rotation which is connected the used side... Why I seem to switch and jump is a bit odd...

I don't know, I know I can switch its "direction" at will, but if I watch it long enough, without attempting to switch it, it reverses itself, and I start seeing it going the other way. Maybe my brain gets tired of seeing it one way and switches off a portion and turns on the other? *shrug*

well, I know for sure if one does not think an object is "right there on the table", and they go looking on the table for it, there is a good possibility they will not see what is right there in front of them. I have experienced this so many times I am embarrassed by it :- )

Stand far away from it (about 10 feet) and start to close and blur your eyes while staring at her feet. If you then focus her moving the opposite direction it does. Then fully open your eyes again. Amazing

Hmm, I can change it at will. 180o counterclockwise, 180 o clockwise, back and forth. Sometimes it stops for a half second, then changes direction when I think it.

At this point, because of the silhouette, we can't tell of she is facing us or has her back to us. At this point, you can easily change the rotation, which is based on our brain "filling in" the missing parts.

Here is a trick, as soon as you lose sight of her breasts (I know, odd place to look, but it works), assume her back is to you, instead of her front. Each time you do this it should change direction.

So whenever you see the image in my comment, it is the back. There is no front, she is never facing you. Think of it that way.

We need an edit function

I havn't slept in a very long time so I don't have that much control over it... I can make it change but it's not reliable...

that is freaky but cool. at first it was clockwise, but then it was counter clockwise.

If I focus really, really hard on just the shadow and think "anti-clockwise! Anti-clockwise", it spins anti-clockwise... Until I blink... Then it just switches back.

i saw nothing strange...

Just so you know, this is a load of garbage. At least, if you believe snopes it is. Bet then again, most things in life are a load of garbage.

Also notice that the extended leg changes from her right leg to her left leg when she changes direction

I dissagree it is merely a matter of perspective. If their was something to distinguish her legs the illuision wouldn't work.

Nice...... i can see both if i use my peripherals

I've seen this before...it frustrates me every time! I've found that if I don't look right at, but use my peripheral vision, i can make it switch on command.

Man, She's still spinning! I looked at this yesterday and that girl just won't quit. Yesterday I could get her to change rotations but tonight she only wants to go clockwise. I'm getting a bit nauseated (at the rotation, not her figure!) so I'd better quit staring.

I disagree with the left brain/right brain thing, I think that's some pseudoscience someone made up to try and make the illusion more interesting. My logical, rational approach was that if you can see the shadow/reflection on the ground, you must be looking slightly downwards, so can see the instep of the foot not the sole, and therefore she is rotating clockwise as seen from the top. This, apparently, makes me right brain which I will be the first to say is complete tosh. Now here's an interesting trick. View it so the woman is spinning clockwise, then cover the bottom half so you can only see her arms and head. Her head is tilted towards the right shoulder, yes? Can you see that as her left shoulder? Didn't think so. Now uncover the image, view it so she is turning anticlockwise/counterclockwise/widdershins, and recover the bottom half. Which shoulder is her head leaning towards now?

I second this, it's just perspective. It's a 2d figure, so you don't know when the leg is either behind or infront of the other leg, which makes it turn either way. no left or right brain thing

I can see it both ways!

Hmmn....If I think of it going clockwise, it goes clockwise. If I think of it going the other way, I see it going the other way!

Or you just look at the foot at the bottom and make it twist the other way.

For a few seconds when I was looking at it looked like her foot was twisting in the opposite direction that her body was.

That's how you do it. You stare at her foot and make it move in the opposite direction of her body and after one rotation she flips sides.

I remember this... I used to be able to make it switch directions pretty easily, but now I'm having trouble. I found that if you cover everything except the foot that isn't lifted, you can make it switch more easily and then slowly uncover the rest.

cool she switches but now shes stuck on my left brain....never mind back to my right........

Ah, it's this again. She's spinning CCW. I know it can be seen the other way, but that shadow says it's CCW.

The lighting is coming from behind. That's the only way that the extended foot's shadow can appear in front of the "standing" foot. This is true if you think of it as a reflection as well.
