Participants
In this study, the 19 participants (age range: 18-25, 7 males, and 12 females) were students from the University of California, Los Angeles. None of the participants self-reported as being colorblind. Participants were credited for an undergraduate psychology research methods course requirement. No monetary compensations were given.
Design
The design used for this experiment was a one-way within subjects experiment. The study analyzed the Stroop Experiment that tested response time between neutral and incongruent ink color and word. The independent variable was the relationship between the word and ink color. The two levels of independent variables were: (a) neutral, when the word was unrelated to the ink color …show more content…
The experiment required two rectangular white posters three by two feet. Both the independent variable posters had two columns. Each column had ten words, totaling 20 words on each poster. The poster was placed at the same height and distance for all participants. The poster had block randomization; however, there were constraints. The poster was blocked in quadrants (five words each) and required that the words contain no color or word repeats within each block section. There were five words and five colors that were repeated on both posters, but the randomization occurred without replacement within each quadrant. The number of letters and syllable(s) of each word in the neutral poster corresponded to the incongruent poster, respectively. Additionally, the ink color and the first letter were identical on both posters. For example, “boat” and “blue” were both written in red and were the first words on the neutral and incongruent posters, respectively, followed by “yogurt” and “yellow”, “brain” and “black,” etc. Ultimately, both the neutral and incongruent posters were the same besides the actual words printed on the poster. Neutral poster. The neutral poster included the words boat, yogurt, brain, rat, and goose. The colors on the poster were red, green, yellow, black, and
