Click For Summary
The discussion revolves around an optical illusion of a spinning figure, with participants sharing their experiences of perceiving the direction of the spin—clockwise or counter-clockwise. Many users report initially seeing the figure spin in one direction before being able to switch to the other with varying degrees of effort. Some attribute their perception to brain hemisphere dominance, while others suggest that focusing on specific details, like the shadow, can influence the direction seen. The conversation touches on the complexity of visual perception and how attention can alter one's experience of the illusion. Users also discuss the implications of this phenomenon in relation to creativity and cognitive processing, with some humorously referencing the figure's appearance and the differences in how men and women perceive visual stimuli. Overall, the thread highlights the intriguing nature of optical illusions and the subjective experience of visual perception.

The shadow is the thing on the floor, below her. It breaks the CW, CCW degeneracy.

haha didn't even notice that shadow. I remember I saw this show about the brain on Discovery Channel. They were talking about how the brain processes what you see, and they showed you this complicated card trick that you have to pay close attention to. Meanwhile, as they switch from angle to angle the background changes colors, the magician changes clothes, even the table on which he is doing the trick changes... of course the whole point is that most people don't notice all this is going on because you are so concentrated on his hands doing the trick.

must admit it blew my mind that I didn't notice all this was happening before my eyes when it looked so obvious when they replayed the clip.

I seriously doubt it. I removed the left side of my brain, but it had no effect on my thought process.
Then I removed the right side. Still nothing.

I can get her to change directions. Focus on the part between her bottom foot and her shadow.
 
  • #34
oh wow...I couldn't figure it out how you got it to go the other direction and then it was weird, because I scrolled down the page and just looked at her feet spinning and then I concentrated and lo and behold it turned the other direction...the strange part is I could sort of feel my brain changing either focus or sides?! but it only lasted for about 2-3 spins and then she or my brain decided to make her go the anticlockwise way. (yes I sound loony now)

I seriously think that my brain likes the logic part better...
 
  • #35
I now think that I'm fighting with my brain...I have to REALLY concentrate and try to make her go the other direction...and it was sad how I lost concentration within half a spin and she went the other way...internal struggles...
 
  • #36
I can make it go either way at will, but the shadow is definitely a blooper.

I kind of remember this 'dancing girl' image from another thread about 6 or 8 months ago

I don't see how you can draw any info from the shadow, a shadow more than anything does
not have a direction, it is just a shadow of the original and will more with the original.

I think there maybe some key frames which set the direction possibly, apparently some
frames indicate a direction. There is a site which shows that anyway.

I think it is like a spinning cross, where the arms would just longer and shorter.
its up to you to choose the direction.
If I close my eyes, and maging a direction then open them I can get it to go that
direction more often than not.

After a while I got it so I could see her leg just waving back and forth in front.

Oh my god...if I stare long enough she starts doing the Macarena...

I took this test to check my brain out.

http://www.wherecreativitygoestoschool.com/vancouver/left_right/rb_results.pl

I am 52 left 48 right.

I came out 55% right and 45% left. Some of the questions sre 'difficult' to answer though.

By the way the link you posted shows you are 0% left and 1% right.

I wonder what happened to the rest of it?

Good point! The shadow breaks the degeneracy. I can only picture her going clockwise (looking from above), but absent the shadow, I know that she can be just as easily pictured going counter-clockwise. Still, after a minute or so of trying (with the shadow hidden), I couldn't get myself to picture a counter-clockwise rotation.

PS: See also: http://www.michaelbach.de/ot/fcs_hollow-face/index.html

What's wrong with the shadow? I can see it going either way and including the shadow both ways. It just takes a few seconds of trying to focus on certain points in the rotation rather than watching the whole thing to get it to switch. The shadow follows.

If the rotation is wrong, her foot is moving away from us when the shadow moves towards us.

No, the shadow will appear to move that same direction too. It just looks like it's entering from the other side of the screen.

I think the light 'source' changes to compenate for that?
 
  • #47
I see her rotation vector as up (clockwise) most of the time. If I work hard, I can make her rotation vector point point down (counter-clockwise).

My wife see her as clockwise most of the time.

The shadow works for clockwise.

For my, it's not which way the shadow moves, it's where the shadow is.

So now the really important question is -

is she spin 1/2 or integer spin, i.e. is she a fermion or a boson?

:biggrin: :-p

Now I see!

She's a quantum superposition of spin up and and spin down. When we observe her spin, we collapse her wavefunction to a definite spin, either up or down. When we look away, or when our minds wander, the superposition is restored, and the process starts all over.

Maybe I can't get her to reverse because of the Pauli Exclusion Principle...:rolleyes: Waah!

I totally see it going counter-clockwise. I tried staring at it for a bit to see if it goes the other way, just can't seem to see it like that. I'm not sure it is possible for it to go clockwise, or is it?

I am not sure if staring at it helps, it might work better if you close your eyes or
look away for a while.

See who steps out of line first :smile:

After thinking about it for a long time, I can finally switch which direction I think it looks like she's going at will. :D
 
  • #57
Every time I see it it seems to be going in a different direction.

Cool illusion
 
  • #58
Haha wow! I got her to go side to side without ever doing a full rotation in either direction. Look slightly BELOW your monitor, so that you see her moving in your peripheral vision. She'll go left, then right, left, then right. But never round-and round.

There is obviously a pair of women spinning simultaneously in both directions, both occupying the same space. Pauli does not apply here. Definitely a boson.

Both, it started off going anticlockwise and then went clockwise after a little while. You can be left eye dominant and left brained though, so I'm not sure how much if anything this proves, I am right eye dominant, so it's perhaps unsurprising I saw it go anticlockwise first, until my brain kicked in and now it can go either way according to whether I blink or not. :smile:
