ABSTRACT
The aim of research was to study automatization process that was performed in the study by John Ridley Stroop and named Stroop effect. In this experiment random sampling technique was used to determine twelve participants from American International School of Zagreb. By performing repeated measure design, participants were all under same conditions in the quiet room where they performed three different tasks, each participant separately. All tasks were timed separately and mistakes were counted. Participants were given consent forms and were briefed at the beginning and debriefed after the experiment. Later the results were processed and participants were informed about them. From the results it can be concluded that it took participants longer to identify the ink color of the words, in the third task, than to tell the color of the squares, in second task, or read the black words, in first task. Difference between reading the words and telling the ink of the words is 16.8 seconds, where the difference between telling the color of squares and telling the ink of the word is 13.0 seconds. It can be concluded that nature of automatization interferes with other tasks, which means that while trying to tell the ink of the words, the brain also
