HOLY CRAP! She normally spins counter-clockwise, but when I'm listening to music, she spins clockwise!

**P8riot** · 10-10-2007, 09:53 PM

OMG - So if I listen to music while I am reading beforelooking at it - It might be a DISCO!

- I think there is something to it.. it does change relating to what I am doing.

That's interesting! It could be that if you're looking at her after reading this thread you've got a different part of your brain working on understanding her than you would if you're digging on some tunes.

**thegreatnardini** · 10-10-2007, 11:37 PM

Well I've been staring at the damn picture on for about ten minutes now, and I can't for the love of God get her to spin counterclockwise. I even gave up and came back, and I still don't see her spin the other way *sigh*

Well.. I dunno.. it doesn't matter what I am reading - I did that earlier when I checked it out.. it didn't matter what I was reading.. it went CCW. Now I was working on some engineering stuff on CAD drawings and it stayed CW - I don't think that is normal in my field.

I don't think it is a prank.. but I'll be mad if it is.

Oh.. and I can't get the direction to switch using any of the approaches other members have mentioned so far.

**El_Gringo_Grande** · 10-10-2007, 11:59 PM

I was able to time it and got it to switch somewhat reliably. I got in a rythm of looking away and back. For about six times in a row it went from ccw to cw.

It's definitely not a prank. Download the image, look at the frames and play it on your own PC. You'll get the same results.

The animation does have 34 frames, but it only has the dancer rotating once. The fact that it's a silhouette with no depth reference prevents you from being able to tell whether she's spinning clockwise or counterclockwise. So, like the dragon illusion that Fenix posted a while back, your brain just picks a way to make sense of the image.

Yeah - that is my take on it. But am a skeptic.. this one is cool though..

I think it is interesting the changes depending on what I am doing without 'forcing' anything.

**Sirusblk** · 10-11-2007, 01:50 AM

I think it could be that you're using more of your other brain when you're listening to music.

One is more artistic, if you're exercising that side then you see it go one way but when you're not then you see it go the other.

PhoenixxFire · 10-11-2007, 02:27 AM

It took me a while, but I figured out a little trick for myself to change it at will (I can see it switch before either direction completes a full rotation), since at first the only thing I could see was CCW. All I have to do is wait until the instant the legs cross over each other and then anticipate the direction that the moving leg will be traveling when it exits this small time frame.

Ok, after looking at it for a little longer, theres another thing to note: try to lose any notion of an identifiable "LEFT" or "RIGHT" side. This means that as she turns sideways just lose track of which hip is which, as well as her arms.

**Rali3gH** · 10-13-2007, 12:09 PM

This is definitely real and not a prank because I got to the point where it looked like she was just swaying back and forth rather than spinning. That is to say that everytime her foot got to one side or the other it looked like she changed direction so she always had her foot in front of her and never turned all the way around.

Ahhh my brain hurts trying to do that. I just get the legs rotating in opposite directions.

The left-brain right brain distinction in pop psychology is garbage. What you are seeing is a typical bi-stable illusion due to a lack of visual depth information.

The same bi-stability can be seen in a static display of the necker cube.

Which side of the cube makes up the floor, and which sides make up the wall? most people see this one way for a while, then another with the floor being a wall one minute and then the wall becoming the floor the next.

One you have determined what it is, it can be difficult to change your perception of its orientation.

What you see first depends upon your experience in interpreting 2 dimensional figures without adequate depth cues.
Why it changes is at the heart of perceptual theory.
Gestalt psycholgists had an interesting explanation: dynamic brain feilds organize perception accrodig to laws that govern the behavior of particles in a field with an attracitive force.

Although the brain does show laterality of functions, (language is in the left, special abilities are on the right) one side of your brain is not more dominant than the other. everything we do requires both hemispheres. information from both eyes goes to each hemisphere.

What is interesting is if you view it in the left or right visual field, it will go to the contralateral hemisphere first before crossing the corpus calosum to reach the other. Viewing the image in your left visual field should result in faster recognition of the form in the image than if you viewed it in your right visual field.
