This Girl Won’t Stop Dancing in My Brain
Posted by Jerry on October 31, 2007
This is the best illusion I have seen so far: the best because I still haven’t figured out how to be “disillusioned” of the illusion. Okay, too cryptic?
The illusion is of a girl twirling around in a circular motion. People who use more of the right side of their brain will see the girl turning clockwise, and those who use more of their left side of the brain will see the girl twirling counter-clockwise. Apparently, if you focus hard enough, you can switch the direction of her twirl.
Here’s the thing: I’ve been staring it at for far too long than is healthy for a gay man to be staring at a dancing woman, and I can’t get her to flip the direction of her twirl in my brain! What is particularly distracting to me–believe it or not–are her breasts! I keep taking my cues of her spatio-temporal position by focusing on her breasts to get a sense of the direction in which her body is turning. Her breasts also serve as the indicator of when she is directly “facing” me or when her back is turned toward me.
I want to specifically hear from the left-brained people: did you really see the girl twirling counter-clockwise when you first saw her?
Next, I want to know if anyone was able to actually switch her direction: Was it effortless? Easy? How did you manage it? Can you sustain any one direction for a while by sheer will? I know that once the brain “knows” the trick of an illusion, it’s hard to get it fooled again for too long.
According to the site, here are the left and right brain functions:
LEFT BRAIN FUNCTIONS
words and language
present and past
math and science
knows object name
RIGHT BRAIN FUNCTIONS
“big picture” oriented
symbols and images
present and future
philosophy & religion
can “get it” (i.e. meaning)
knows object function
