"Stroop Effect"

The famous "Stroop Effect" is named after J. Ridley Stroop who discovered this strange phenomenon in the 1930s.
Here is your job: name the colors of the following words. Do NOT read the words...rather, say the color of the words. For example, if the word "BLUE" is printed in a red color, you should say "RED". Say the colors as fast as you can. It is not as easy as you might think!









The words themselves have a strong influence over your ability to say the color. The interference between the different information (what the words say and the color of the words) your brain receives causes a problem. There are two theories that may explain the Stroop effect:

Speed of Processing Theory: the interference occurs because words are read faster than colors are named.
Selective Attention Theory: the interference occurs because naming colors requires more attention than reading words.
I think that this puzzle would be easier for a very young child than for older children or adults. Try this out on some small kids who know their colors, but cannot yet read! I would imagine that the children would not get confused by this puzzle because the words would not have any meaning to them.
