With the following exercise you can determine which side of your brain left or right is dominant
Close your eyes for about 5-10 seconds then take a look at the picture above.
If you see the dancer rotating clokwise it means that you use the right hemisphere of your brain more intensively. However the counterclockwise rotation means that you use the left hemispheres of your brain more intensively.
The most people have only one brain hemisphere in use and they are able to detect only one rotating direction. However, some people are able to recognize both directions, especially those who have strong imagination power. Only a very few people are able to intentionally influence the direction of the observed rotation and deliberately change the functions of the two hemispheres.
You can try it!
Now it is an established fact that special trainings such as autogenic training can affect the brain and the brain can be consciously directed in different states, wich states can also be determined by special instruments.
After having a short practice try to reverse the direction of rotation of the dancer! If you have success, try to keep this for a short perod of time, even if you think this is an unnatural direction. If it was done, you have to try to rotate back and forth!
The ultimate goal is, that you make a number and also
a direction of rotation what you ever want.
People who see the rotation of the dancer clockwise direction have the right hemisphere dominant. Some researchers demonstrated that the majority of men fall into this category. These people see the reality in pictures, are dreamy and forced guessing because they get only partial information from the left hemisphere. They are emotional, imaginative, curious and proactive in nature, whereas the right brain thinks in pictures.
People who see the rotation of the dancer counterclockwise direction have the left hemisphere dominant. Many people contend that a significant proportion of women belong to this group. The left hemisphere of the brain is responsible for speech, logical thinking and rational conclusion. These people can be characterized by their concern, doubt, caution, excessive immersion in the details.
Interestingly, the researchers say unanimously that the children do not have distinct orientations, this means that they are able to use both hemispheres. The two parts of the brain complement each other and for this reason children have strong logic skills and also fantastic intuition skills.
The question why these change with age has not yet
How does this illusion work?
It is a two-dimensional image that is
simply shifting back and forth. But our brains did not evolve to interpret
two-dimensional representations of the world but the actual three-dimensional
world. So our visual processing assumes we are looking at a 3-D image
and try to interpret it as such and without adequate clues it may just
arbitrarily decide a best fit spinning clockwise or counterclockwise.
The right and left brain function can be measured with a simple instrument that allows accurate measurement of the brain activity. This instrument named Egely Wheel and it is commercially available (price is about 200 $)
