Abstract
This research is designed to study attention and automatic processing of the brain by replicating the Stroop effect experiments that was conducted before. The participants included 12 female and 6 male students from Cal State Fullerton. Coglab, a virtual lab, was used to conduct the experiment. On each trial they were shown a word (RED, GREEN, or BLUE) that was printed in either red, green, or blue font color the assigned task was to classify, as quickly as possible, the font color, regardless of the word name. The speed of reaction time was measured and the hypothesis is that the RT of the matching color and word would be smaller than the RT of the different word and color. The results did support the hypothesis and thus replicated the stroop effect experiment.
The Stroop Effect
All of us have certain tasks that we do so repeatedly that they become kind of automatic in a sense where full conscious effort can be significantly lowered in order to perform it. For example, driving, it is so part of our daily lives that we somehow drive effortlessly. The process of making something automatic is interesting because it is an important part of daily life. We perform a variety of automatized behaviors quickly and effortlessly. In some cases people report that they do not consciously know how the behavior is performed, they just will it to happen, and it does happen. To explore properties of automatized behaviors cognitive psychologists often put observers in a situation where an automatized response is in conflict with the desired behavior. This allows researchers to test the behind-the-scenes properties of automatized behaviors by noting their influence on more easily measured behaviors. This demonstration explores a well-known example of this type of influence, the Stroop effect.
