Running head: EXPLORING THE STROOP EFFECT Racing Hoses and the Stroop Effect Milana Istakhorova Brooklyn College – CUNY Fall 2011. Abstract The research assessed in this article discusses the Stroop effect. The Stroop effect occurs when our selective attention fails and we are unable to attend to some information and ignore the rest. This study tests the Stroop effect by presenting the participant with a congruent or incongruent word and the participant is asked to type the color of the word or the actual word in a series of trials. In this research, it has been found that participants had faster reaction times for congruent items and slower reaction times for incongruent items. In addition, participants had faster reaction times when…show more content…
Method Participants Twenty-one undergraduate, male and female students were recruited from an experimental lab class at the City University of New York Brooklyn College. Materials and Design In this within subjects design, we used a 2 (Congruency: Congruent vs. Incongruent) x 2 (Task Type: Naming color vs. Naming word) factorial; the dependent variable measured was reaction time. The stimuli were presented on a seventeen inch computer monitor and participants were given a standard keyboard for their responses. The software used for this experiment is METACARD. The stimuli used were four words: red, green, blue, yellow; and four colors: red, green, blue, yellow. For the independent variable of congruency, there were four possible congruent items and twelve possible incongruent items. For the independent variable of task, there was one block of forty-eight trials asking the participant to type the word and one block of forty-eight trials asking the participant to type the color. The order of each block was randomly determined by the computer for each participant. Half of the participants did the word naming then color naming; the other half did color naming then word naming. Each trial begins with the presentation of a fixation cross in the center of the screen, visible for 500 milliseconds. The fixation cross is removed and immediately followed by the word and color stimulus; this
