Stroop Experiment Essay
Method Participants
168 psychology students at Binghamton University enrolled in Research Methods (PSYC 344) participated in this study. 113 of these participants were females (67.26%), and 55 were males (32.74%). Of these 168 participants, zero were freshmen, 18 were sophomores (10.71%), 112 were juniors (66.67%), and the remaining 38 were seniors (22.62%). No participants received compensation for participating in this experiment. These participants were divided into six groups based on where they were sitting. Design
The Stroop Test was used in order to test the effect of interference on reaction time. This was done by using three different types of slides, each with either 20 words or 20 colored boxes, and recording how many words participants could read the color of, rather than the word itself. The colors used in this experiment were red, green, blue, purple and brown. Materials The slides were projected onto three screens in the front of the room. Participants were handed small slips of paper with …show more content…
The results showed that F(2, 334) = 259.8, p < .001, MSE = 5.9. There were two planned contrasts for this experiment, the first was the congruous versus incongruous conditions. As shown in Table 1, the mean number of colors read for the congruous slide was larger than in the other two conditions. For this contrast F(1, 167) = 419.4, p < .001. The second planned contrast was the no words versus the incongruous condition. As shown in Table 1, the mean for the number of colors read for the no words condition was higher than that of the incongruous condition. For this contrast F(1, 167) = 307.9, p < .001. Calculations for the Reffect for both contrasts are shown below. The contrasts show that the congruous condition resulted in the fastest reaction times, and incongruous condition resulted in the slowest reaction
