Not a brain test: Which side of your brain are you using?

  • If you see this lady turning clockwise you are using your right brain.
  • If you see her turning anti-clockwise, you are using your left brain.
This was a popular conclusion based on a previous study but according to a recent article:
But while the dancer does indeed reflect the brain savvy of its creator, Japanese Web designer Nobuyuki Kayahara, it is not a brain test. Instead, it is simply an optical illusion called a reversible, or ambiguous, image. Images like this one have been long studied by scientists to learn more about how vision works.
    You can see which part of the brain you are using by checking this dancer, click on the image:

    Ok so this is weird. I too see her switching back and forth. Is there something wrong with my brain????

    Originally I saw her rotating counter-clockwise then I asked my father and he said it was moving clockwise then I saw it as clockwise for a minute then it went back to being counter-clockwise. Did I tap into my left side? Or did I make myself believe that it was moving in that direction?

    As mentioned in the post, ppl believe this is a brain test but it is really not. It is just that the picture lacks depth information and so can be used to believe the dancer moves in any direction.

    originally i saw her rotating anti clockwise and after a minute or two she started rotating clockwise. what does that prove? am i supposed to conclude with the first observation or the second?

    so, i can control which way she turns, with my thoughts, am i just a boss?

    The dancer switches direction after about a minute. Obviously. Not only does she switch direction but the leg that lifts up for the twirl switches as well. This is a normal ballet maneuver and it does not make sense for the woman to be spinning against her foot. I don't know who they are trying to troll, but this makes the "test" much more skeptical.

    look directly at the shadow of her foot. it will make her switch to other direction you would like to... :)

    Good example of a Brain Study: If you can read this OUT LOUD you have a strong mind.

    If you can read this, you have a strange mnid, too. Only 55 people out of 100 can.

    I cdnuolt blveiee that I cluod aulaclty uesdnatnrd what I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it dseno't mtaetr in what oerdr the ltteres in a word are, the olny iproamtnt tihng is that the frsit and last ltteer be in the rghit pclae. The rset can be a taotl mses and you can still raed it whotuit a pboerlm. This is bcuseaethe huamn mnid deos not raed ervey lteter by istlef, but the word as a wlohe. Azanmig huh? Yaeh and I awlyas tghuhot slpeling was ipmorantt! If you can raed this, forwrad it

    I could read both of the above out loud quickly and without hesitation. This has resulted in a severe pain in my right shoulder, as after reading these examples, I extended my right arm vertically above my head, bent it at the elbow, and proceeded to pat myself on the back. Seriously though, there is something about which I'm curious. I can be a lazy reader, or sometimes just tired and have to finish reading something, so to concentrate on it more, I'll flip the book upside-down and continue reading. Which side of the brain am I using at that point? (Please don't say the inside.) I've also flipped a text and read it in a mirror without too much hesitation in comprehension. Would this be triggering the same hemisphere as the above example? M
