Absract: This experiment was conducted to investigate the demonstration of interference in the reaction time of a task. The participants of this experiment were students who had study hall and who were 11th and 12th graders. The aim of this study is to investigate how much time it took to read the words from the first sample to second sample. Introduction: 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. Participants take a lot longer to name the color of ink that words are written in when the words themselves are contradictory color words for example red is written in yellow ink. A study related to the stroop can be, Dalrymple-Alford, E. C. (1972). Associative facilitation and interference in the Stroop color-word task. Basically the aim of study it is difficult to name the color of a stimulus when the stimulus is a word naming a different color. When the word is congruent with the color in which it is written, color naming is much quicker. Similar results are also obtained when color-related words are used instead of color names. These results are taken as evidence for the operation of associative factors that could facilitate or impair performance in the color word task. So basically the procedure was that there were categories of words were used: unrelated words (joy, hand, and... ... middle of paper ... ...itten in the same color, results are shown in the pages after. I noticed that no one made a mistake and took pretty quick to read them. The mean for trial 1 is 13 so the average is 13 secs, The median for trial 1 is 12.48. The standard deviation is 7.3598007..So for trial two we see that we have gotten different results. In this trial the color of the ink does not match the name of the color. While doing this experiment I noticed that it took longer for the participants to say the color. Results are shown in the next pages. For this trial there is no particular mode because the results are different. The mean is 32.1044, meaning the average time it took was 32.1044 secs. The median is 32.18. The standard deviation is 5.625689. So basically the results we see that it does take longer for us to say the name of the color while the word is written in a different color.
