Are you left-or-right-wired?

It is the test of the Right brain with the Left brain, and it’s time to concentrate, not on the lady, but her movement, that’s gonna decide the rest. If you see her moving clockwise, then you’re using the creative side of your brain, that is the Right. Whereas, if you see her move anti-clockwise, then you’re using the logical part of your brain, that is the Left.

Which way are you, or rather, how accurate do you think this test is?

I first looked at it and saw her moving clockwise. Then I thought about making her look like she was going anti-clockwise and she started going that way. Now I'm trying to conciously see her going clockwise again and I can't do it (Because I'm trying to force it, using the analytical part of my brain I guess).

I tried my darnedest best to see her going counter-clockwise, but I can't manage it :(

She goes much more naturally counter clockwise for me but I can force it the other way with a couple of seconds concentrating. It appears doing so back and forth 6 or 7 times in a row can give you a bit of a headache though.

That's exactly what I was about to say. I can't get her to go clockwise again.

Hasn't this been dis-proven as a personality-indicator and thought to be more along the lines of an ordinary optical illusion like the Rubin vase? The way you see her doesn't really chalk up shit other than the one way your brain decides to interpret what it's seeing at the moment. I can "make it" go either way, no big deal.

Also I swear this is like the fifth or sixth time I've seen this posted here.

You can hold a gun to my head and I still won't be able to make her go anti clockwise. I guess my logic gave up a long time ago.
Reminds me of the dolphin illusion.

Identical results. It was kinda fun to see my brain switch interpretations by sheer force of will, but I can't switch back.

Hm, for me she seen to be spinning clock wise, generally. Although in the past I have try to vision her spinning counter clock-wise too. I think there are some drawings that details the type of topography that follows it, although I have misplaced it.

Oh cool, I can make it go either way now. XD

Just a few extra seconds of concentration...

I find that you can change it in a couple of seconds if you scroll up so that you can only see her head, then keep it out of your direct field of vision and decide which way she goes. The leg becomes a really distracting factor.

That's what I was looking for too think I found it cause I got her to spin anit clockwise.

Looking alternatively at the heel of her straight leg and its reflection is what makes her switch directions for me. Can't quite explain why though.

Going all walleyed and then thinking the direction really hard is what does it for me. The mechanics of how the hell that works are beyond me.

I look at the heel to change directions as well.

At first glance, I see clockwise. But then after a few seconds, she's going counter clockwise.

Definitely seen this before, but it's always fun to see if you approach it differently.

Yeah, Tails is right here.
There is absolutely no information regarding one's mind that can be gleaned from this optical illusion, aside from perhaps the flexibility of your spatial perception. The whole left-brain right-brain tagline that usually accompanies this image is nonsense.

I find a really effective method of rapidly changing the direction I perceive the woman to be turning is by looking at the shadow of her foot.

I cannot for the life of me see her moving counterclockwise. She's clearly moving clockwise, all you people are just crazy. :|

Now try switching back and forth:

That's really cool. It's going slow enough you can make her change before she goes in a full circle. I had the leg bouncing back after the first quarter turn.

Interesting. It's a bit more difficult to switch direction at that speed, for me.

For me it's when the outstretched leg comes back toward center, as it vanishes into the silhouette you can decide whether it's in front or behind, and that alters your perception accordingly.

It isn't nearly that conscious of a thing for me, I just concentrate on seeing it the other way and then after a turn or two it changes.

Eh, I was wrong anyhow. I think I'm just seeing the outstretched leg as always going behind. The result is when it hits either the left or the right extreme, I can picture it going back behind the leg instead of going forward. Point is, I think that's the decision point in either case, the slower one just makes it more possible.

Started out clockwise, and fell into an easy switch to counter-clockwise, which ended me stuck for a while. It seems like a pretty malleable piece of perception though, as after training myself to switch with the shadow, I could pretty reliably get it to flip at each of the most elongated points. It may say more about your brain (if anything) in how you are able to convince it to flip the image.

Using the slow one, I can with difficulty do what Radez was describing and flip it at the center, although that makes the back of my brain hurt. Particularly trying to do 1/4 turns.

Am I odd, since with direct sight I picture clockwise, but I produce counter-clockwise with peripheral vision?
