Left Brain Right Brain & the spinning Girl

04 Feb


Take a look at the spinning girl. Do you see it spinning clockwise or counter-clockwise? I see it spinning counter-clockwise, but i was able to switch it in the other direction, its hard for many people. Give it a try.

The spinning girl is a form of the more general spinning silhouette illusion. The image is not objectively “spinning” in one direction or the other. It is a two-dimensional image that is simply shifting back and forth. But our brains did not evolve to interpret two-dimensional representations of the world but the actual three-dimensional world. So our visual processing assumes we are looking at a 3-D image and is uses clues to interpret it as such. Or, without adequate clues it may just arbitrarily decide a best fit – spinning clockwise or counterclockwise. And once this fit is chosen, the illusion is complete – we see a 3-D spinning image.

By looking around the image, focusing on the shadow or some other part, you may force your visual system to reconstruct the image and it may choose the opposite direction, and suddenly the image will spin in the opposite direction.

      It happens. Try it. You try this way – do not look straight, look at an angle. Give a try, may happen. For me it is happening. Suddenly she changes the direction. Good luck.

        Does it happen for Aspergers as well? Hard to not be irritated with the shades.

    Strange but true. I can make the image spin both directions. Ty for the insight!

    Interesting! I was able to spin it the other direction by looking at the shadow of the foot.

      Yes it happens. For me too it happens but many reported it does not rotate in other direction for them. Thank you for your stopping by and liking it.

    Yes, by looking away a quick instant the image changes spins, I could make it go back and forth – but I would like to see a man’s silhouette too …

      Thank you very much for stopping by and liking the post. Its really surprising that you could make the girl back and forth! I have not experienced that.I will try it. Thank you for your nice comment.

        The trick is in the eye movement. It distracts the brain.

        You are correct. Thank you. !! 🙂

    i see it spinning clockwise. and my brain doesn’t like that i can’t make this experiment work. why can only “some people” do it?! 😦 now i’m frustrated, haha

    I see it spinning both ways, but it also seems that my brain chooses clockwise a little bit more. Have you any idea why it is like this! I mean, why some people can see both ways, and other people can only see clockwise or counter clockwise?
    In one comment was mentioned Aspergers syndrome, and I have ADHD + a little bit of Asperger. So I’m a bit curious if that has something to do with how the brain interpret the picture.
    By the way! This blog of yours seems very interesting! Gonna read a little bit more! XD

    The shadow can help to switch the movement. It’s the trick I used to get easier the change of spinnig direction. Anyway, I see easier the movement against the right hand criteria.

    This is a very cool mental exercise! I thoroughly enjoyed trying to see if I could reverse the direction. It takes a few seconds but I can now switch back and forth. Thanks!

    Cool! My brain saw it spinning clockwise first, but I could easily switch it. For me, looking down – either at the shadow of the feet or even at my computer – and then looking back up seemed to do the trick.
