If you are seeing this lady spinning clockwise, then it means you are using the right side of the brain. If you are seeing her spinning counter-clockwise, then you are using the left side of the brain.
Some people are able to see her spinning in both directions, but most of them see her rotating only in one. If you can see her spin in one directions and then make her spin in the other, then you are a part of a handful of people.Even if it might not seem so, both directions can be seen. Apparently, this fact has been proved at the Yale University, USA, after 5 years of studying the human brain and its functions. Supposedly only 14% of the US population can see her spinning in both directions.Note: I saw her go counter-clockwise, but then if I only looked at her feet, she started to spin clockwise. It took a bit longer afterwards to make her go counter-clockwise again. I have noticed that the illusion is caused by the perception of the viewer as he or she interprets the ambiguous frames where the spinning dancer’s body (legs and arms) cross over each other.Don’t forget to share your experience with us and tell us which way you saw her go.Need help to see her go the other way?
