This experiment was first conducted by John Ridley Stroop.  He could see that people took longer to name the name of the color if it was inked with another color.  Psychologists all around the world were fascinated with this experiment and some famous scientists have cited this work over seven hundred times.  This experiment consists in placing the name of some colors and has somebody say the name of each color.  Then there is a second round in which the color of the name of the color has a color different than the color it is naming.  He noticed that people took longer to name in the second round. These results occur because your brain can identify faster the color and then it reads so your brain needs to cancel the first option and then choose the second choice.  This is showed with a longer time of reading the word. This is an experiment that shows that multitasking does not exist and that your brain can only take one thing at a time.  First, your brain takes the color of the font then, it reads and processes the words so you can understand them as words and then understand what color you need to say.
