Abstract
This study added to the well know innovation of the Stroop effect and experiment by John Ridley Stroop through a Stroop task experiment. There were twenty participants who completed two conditions, which tested reaction time. For each condition the participants were asked to read aloud the number of digits that appeared on each row as fast as they could. One condition number figure matched the number of digits. The second condition did not match the number figure with the number of digits. After the experiment was done, it showed a significant difference for reaction time between both the conditions. The Stroop task demonstrates

At the beginning stages, reading takes some effort, and conscious attempts at sounding out the letters of each word. As people practice reading skills, they finally learn to read without trying. When a behavior or skill no longer requires direct effort to be completed, cognitive psychologists say it is automatized (CogLab). Automatization is fascinating because it is an important part of daily life. Most people perform a numerous of automatized behaviors quickly and effortlessly. People often think they can multi-task, but classic research by J. Ridley Stroop shows differently. Stroop (1935) demonstrated that if someone is reading information, and other conflicting information is added, the rate in which a person will read the information would slow down. Stroop presented his participant with 100 words, each word spelled out a color, but the ink of the word was different from what it spelled. His participants were asked to report the color of the ink the word represented. The interface of conflicting color stimuli upon the time for reading 100 words caused an increase 2.3 seconds over the normal time for reading the same words printed in black (Stroop, 1935). Stoop found that participants performed slower to read the color of ink when the ink was used to produce color names different from the color of the ink. For example, the participants were slower to identify red ink when it spelled the word blue. The reasoning for this experiment is to test the Strop effect. The experimental hypothesis is that the time of reading the incongruent list of digits will be longer than that of the congruent list of
