Extracts from this document...


THE STROOP EFFECT Miroslav Cuculiza: 201218 IB Psychology: Standard Level Word Count: 2/17/11 Abstract: The aim of this experiment was to investigate the level of interference on attention when naming colors in conflicting word with the color and the color by itself. The hypothesis was that the third stimuli would take longer than the other two. This experiment was to replicate John Ridley Stroop's experiment "The Stroop Effect" in 1935. The experiment had three different stimuli. These stimuli consisted in several words that had to be read by the subjects as fast as they could. The experiment was conducted in the American School of Tegucigalpa. The last stimulus proved to be hardest for all of the students. Introduction: The aim of the study mainly was to investigate the level of interference on attention when naming colors in conflicting word with the color and the color by itself. The first stimulus consisted in names of colors written in black font on a white sheet of paper. The second stimuli consisted of the names of colors written in the same color as the name on a white piece of paper. ...read more.

Both of them are Jose Treasure and Ricardo Vasquez. They did an outstanding job by reading everything really fast. Also, we found out that most of the women did badly on the experiment and maybe it was because they were shy of reading or maybe of getting stuck on a word. By doing this experiment we learned how reading something several times can really play with your mind because first the people had to read the words very easy but at the end when they did not want to read the word, they read it. So with this fact we really found out haw the mind can play jokes on you even when you want to say something, the brain directly sends a different signal to your mouth and you say a completely different thing. In conclusion, this experiment has helped me to make my first psychology experiment in my life and also it helped me to learn a lot of things about psychology and how the mind works etc. There are many differences in sex, race, color but the most important difference in all of us is our mind and how it works because it makes us a completely different person to the rest. ...read more.
