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.

When she is spinning clockwise, and the foot which is lifted up passes in front of the foot which is planted on the ground, then the shadow of the lifted foot passes in front of the shadow of the planted foot as would be expected.

However, when she is spinning counter-clockwise, and the foot which is lifted up passes in back of the foot which is planted on the ground, then the shadow of the lifted foot still passes in front of the shadow of the planted foot and this is difficult to explain.

You guys are all WAY too left-brained to be analyzing the shadow at this level of detail.

This is so weird! I could see it going both ways, but I always see it going clockwise first. I can't figure out how it works, and I can't just pick which way I want to see it; I have to look away or just stare at it for a long time for it to switch directions. It's so confusing though!

I can see both directions such that the shadow looks valid. The "slope of the floor" and position of light source both seem to shift.

This is an example of "perceptual rivalry" as the silhouette gives no clues as to what is left or right, so our brains fill in the missing info. Sometimes the brain makes it clockwise, sometimes the brain makes it anit-clockwise. This is linked to switching between the brain's hemispheres - we all switch between the differrent sides to our brains, but the timing varies from person to person.

For those interested, check out Prof. Jack Pettigrew's webpage. This animation is mentioned at point 7 on the following page: http://www.uq.edu.au/nuq/jack/rivalry.html

I went went cross eyed, and the image split into two images, one spun clockwise, and the other counter clockwise. Then both images together began rotating one way on the horizontal axis, and on the vertical axis. Then that entire visualization split into four, and began some complex pattern that seamed to be also linked to a strange glowing orb that surrounded the whole thing, and got brighter and dimmer, and switched colors depending on which eye I concentrated on.

I don't think so. The degeneracy is broken by the fact that the observer is on one side of the woman, not by the position of the light source.

does us being able to switch directions mean that we can switch our dependence or reliance or usage from the left to the right side of the brain and vice versa?

If I look to the left, right, or bottom of the image and use averted vision (useful in observational astronomy) I can manage to see her spinning counter-clockwise if I put my mind to it. Looking at or above the image, she always spins clockwise, and I can't seem to change that.

I saw clockwise no problem, but I had to scroll down and focus on just a small part of the foot before seeing it go counter clockwise.
 
  • #72
I initially saw her spinning counterclockwise (when did it become "anti" anyway?) and that was it. Then I read lisab saying to look to the side, and the I saw the image spinning clockwise. Once I see her moving clockwise, though, I can't get it to switch back to counterclockwise. That's a very, very cool effect.

this is important because if we can then this raises many questions.

At first she appeared to rotate clockwise. Then I read some text- then she rotated counter-clockwise. I looked away at a photo, then looked back and she was rotating clockwise again. I read some text again and she reversed direction. Looked away at a photo and when I looked back again she had reversed direction again.
For me it seems that stimulating my brain with text vs. images determines which way she appears to rotate.

If you watch it on here and click on random spots on the video using the bar it is a lot easier to realize that you can see her going in both directions.

Of course you can switch back and forth. The question is can you do this at will? Again the answer is of course if you learn how.

flip the switch in your brain of course :-p

it's funny, I was looking at her and making her just stay facing me while flipping left to right and back and forth again while never seeing her rotating in one whole circle. It's all about mind control. I had fun doing that. (switching from one side of my brain to the other) :biggrin:

Which way are the nipples spinning :smile: ?

Okay, now stop staring at your girlfriend and tell us about the picture. :biggrin:

What?!----MB--do you want a "woman's version"?

(a man spinning, that is)

:biggrin: Honestly, I thought he was just joking. After your comment, I had to go back and look, and sure enough, there are nipples. Just goes to show the differences in what men and women notice. :smile: (I'm not sure that a man spinning with one leg up would necessarily be flattering to the man though...it's funny how a naked woman can jump up and down and men get turned on by everything that jiggles, but if a naked man jumps up and down, the women just laugh at everything that jiggles :biggrin:).

speaking of models...this reminds me of art class and I had to look at a nude male model who was gray haired and had things sagging ALL OVER. I seriously was thinking of burning out my eyes after that and it wouldn't be so hard as the lab is in the building across the street :rolleyes:

But I was lucky that for the long hr draw, his front wasn't facing me, when he sat in the "thinking man" position. Not only that, after we finished drawing, we were ordered to turn our drawings and show the class, and the people who had the front view drew that "area" rather vaguely to say the least. :smile:
