The Stroop Effect

The stroop effect is an experiment that was first conducted by John Ridley Stroop in the 1935. As stated by the dictionary, the stroop effect is a psychological experiment that tests the reaction time of a task. The task taken in consideration is the one of looking at our ability to read words faster and automatically than when we say colors. The cognitive mechanism that is involved in this experiment is called direct attention, you have to manage your attention, stop, think and then respond to it.
"This effect is a demonstration of interference, in which the brain experiences slowed processing time because it is trying to sort through conflicting information." This expirement also shows us that people have a harder time thinking what color the word is than saying the word  the brain delays on actually knowing automatically and takes more time analyzing the  color the letters have. Why this happens? Well, the both areas that are trying to function: read and talk are giving signals to the same area on the brain at the same time, which makes it difficult to process and therefore makes the person say it slower.
The experiment consists of first giving the word of the color with the letter of their same color. The person is asked to read the set of words and they are timed. Then, they are asked to do it again, but this time the letters of the color are painted with another color that does not match the word. They are also timed. The results say that when you read the word with a different color, it will take you more time.
My experiment will be conducted the same way as John Ridely Stroop did, only that I will use high school students, boys and girls to analyze the data and results.
