Dancer Test



Are you left-brained or right-brained? Supposedly, your brain lateralization determines how you view this animation.

Some people see her rotating clockwise. Others see her rotating counter-clockwise. Some see her unpredictably changing the direction of her rotation.

Supposedly, people who see clockwise rotation are right brained. People who see counter-clockwise rotation are left brained.

I originally came across this animation here.

Anybody is free to do any suppositions.
But when everybody is doing the same supposition, it is taken almost as fact.

Why not make similar left/right brained supposition on the Necker cube?

The direction of rotation is both clock and counter clockwise.

I think there is no trick here .... or no optical illusion.

It is quite straight foward ... changing direction...

Watch the animation for about 30-50 secs ... with the idea the direction is changing... you can actually see the instant of changing the direction...

I wonder this has anything to do with left-right brain....

Shrini, not everyone sees a change of direction when they view the dancer. For example, I almost always see her rotating clockwise. My girlfriend, on the other hand, sees the dancer changing direction every few seconds.

Right .... I agree that people see the image differently. I am interested in knowing how do you relate these variations to compartmentalization of brain?

>>>Supposedly, people who see clockwise rotation are right brained. People who see counter-clockwise rotation are left brained.

What about people who see neither? Like me - who see that the direction simply changes at about 10-20 secs.

I am interested to see how you make the connection?

Presumably, Shrini, the more often someone sees the dancer switch directions, the greater the balance of their left and right brain.

However, note that I wrote "supposedly" in the original statement and "presumably" in this most recent statement :-)

I don't know how valid the science is, but it's definitely interesting how different people see the dancer differently.

after i read the first two lines it appeared counter. then i read the third line and looked again and it was clockwise and has not changed back. you have fried my brain.
