Can someone explain how this works (I mean how the lady can look like she is rotating in either direction). If I focus really hard on her foot I can make her change direction, but I can't figure out the illusion they are using.

#12I had her body spinning clockwise and her foot spinning counter clockwise.

#13So, does this actually correlate with IQ in any way (not that IQ is meaningful)? Or is it simply that 14% of the population can make the switch happen, and 14% have an IQ of 160, and the author is making unfounded assumption that making the switch is a function of intelligence.

#14Obvious question: which studies and where are the citations?

#15This has got to be BS:
I looked at it and went "uhh, I can make it do both?", then read the text.
There is absolutely no possible way that I am over 160 IQ and, if I am, dear god I am wasting it.
Edit: in fact, it's kindof fun to sit there and watch the hands dance back and forth, it looks much more like she's dancing and less like she's spinning if you make her switch directions when the hand is either at the far left or far right. Neat.

#16To get her to switch directions I have to focus really hard on her foot, the one on the ground. If I block out everything else mentally I can make it switch directions, but it is very hard. I bet with practice anyone can get to the point where they can see her turn either way with more ease.
That worked for me as well.
What I wonder is, is there any cognitive effect to being in "right-brain mode" or "left-brain mode"? Right now I've flipped myself into seeing her going counter-clockwise all the time (my dominant mode is clockwise), but I don't feel any different.

#18Earlier quoted context omitted.
It says that to have an IQ above 160 you need to be able to see it turn both ways without shifting your gaze .
And you have to be able to do it at will .
I can switch at will. But it took about 30 seconds of initial practice, plus an insight. The insight is that you can't just see her change turn direction - you have to also simultaneously see her instantly switch which way she is facing.

#19We opened several of the animations up on two monitors and were able to get one monitor set going one way and the other monitor set going the other way, it was pretty cool looking.

#20Here's a tip: cover one half of the image with your hand, including all of her body, so you just see the leg come around. Now uncover the image. Now do the same thing with the other half (or two-thirds, whatever).
If you do this a few times, you'll likely be able to see it go both ways. Not at will, but you can get into a mode where you are seeing her rocking back and forth rather than constantly spinning the same direction. The key is that your brain makes a snap decision about which side of her hip the leg is on, and then it's motion processing mechanism stitches all future images to match that initial impression. You can teach yourself to make her switch back and forth by refocusing on her hips.
It worked for me anyway.
