Our left and right brain can conflict with each other as this optical illusion shows.



If you are like most people, you found this exercise hard.


This is known as the Stroop Effect. It is due to the conflict between the direct interpretation or reading of the word and the perception, categorization and naming of the color of the letters. As you can imagine, seeing a color, identifying the color and categorizing it, translating that color into the word, and finally vocalizing the named color takes far more concentration than the natural tendency to simply read the word aloud. It has also been suggested that the task of saying the name of the color requires both hemispheres of the brain to work together.
