Apparently, this is a left-brain/right-brain test. If you see the figure rotating counterclockwise, you are “left-brained,” and you’re “right-brained” if you see the figure rotating clockwise. 

So, what kind of brain do you have if you know how to switch the rotation of the figure at will? While sometimes I wonder if I even have a damn brain, I may have figured out a simple way to explain how to switch the rotation. Scroll down on this image until you can’t see boobs anymore because they may be a bit distracting. Now, as you are looking at the legs, pretend that there are 3 legs. The woman turns into a man! No, really, just imagine the right leg coming around clockwise. As the right leg is coming around on the right side clockwise and crossing the “middle” leg, imagine a third leg appearing from behind the middle leg. This third leg will be rotating counterclockwise. Now scroll back up and try this.

I think that most of this left-brain/right-brain dichotomy is based on where our language centers are located. Broca’s and Wernicke’s areas for language processing are primarily active in the left hemisphere. This is mostly based on decades of clinical evidence from stroke victims, traumatic brain injuries, and fMRI studies. Even with that said, language processing is shared more between hemispheres in some right-handed people and a larger proportion of left-handed people. Just this bit of info precludes a complete dichotomy for language processing, but for simplicity’s sake, the left side is for language. Still yet, the right side of the brain is an emotional and visual integrator, and I think common sense tells us that we need this for some aspects of language and communication. On average, most people use both sides of their brain for most activities. We’re not split-brained. Even if some of us are slightly more lateralized to one side of the brain, I don’t see how a naked ballerina gives us any insight into this. 

Oh yeah, if it’s still not working for you, try blinking as the legs cross.
