Stroop Effect Goal of the article The main aim for writing this article to determine the interference in the serial verbal reaction through the study of several devised experimental materials. The study associates the source of interference in color and word stimuli to the materials used in the experiment. The hypothesis is that the interferences arising from the naming of the colors are as a result, not to the equal readiness of the names of colors as to the equal readiness of the cognitive processes of the colors. The research question is “What effect would practice in reacting to the color stimuli in the presence of the conflicting word stimuli have upon the reaction times of the two situations as described by the hypothesis? (Stroop, 1935)”
Cognitive psychology terms
1. Stimuli: Stimuli in psychology also referred to as cognitive stimulation refers to the manner in which the senses of an organism is aroused towards an action. In the case of this article, stimuli can be attributed to the identification of the reaction as a result of interference in color and word formation (Sternberg & Mio, 2009).

2. Bottom of FormResponse: In cognitive psychology, response determines the change in attitude that is put in a persuasive communication. Response has been attributed with the cognitive response theory in which the insights to persuasion variables are enhanced as is in the article (Eysenck & Keane, 2005).

3. The stroop effect: Refers to the term that is used to demonstrate the psychological difficulty that is experienced in the selective attendance to color and the word printed from the particular ink color (Braisby & Gellatly, 2012).

Description of the independent variables
The dependent variable is the reading of names of the colors serially. The test was that the respondents read through the colors and words in the determination of the effects, interference with the color stimuli had on the words. This variable was measured in two forms. In the first test, the respondents read the color prints in the intended formats while the second group read the color name prints in the reverse order. The reading involved the reading of a word samples before the real tests. In terms of units, the variable was measured by the determination of the reliability of the difference (D/PEd).
Description of the independent variables
For the experiment, the independent variables were the interference to the color stimuli and interference with the word stimuli. In both, the color naming test was applied so as to define their impacts on the serial naming of the colors.
Statistically, the variables were subjected to descriptive statistical tests in which the tests of reliability were carried out. Additionally, the analysis involved the determination of the standard errors, the coefficients of variability, and mean scores.
Description of the experiment’s procedure
Since the experiment was conducted in two different sets, there are two procedures involved although related. The college undergraduate students (respondents) selected at random were subjected to the tests. Instructions were then read to the participants using various sheets and the time spent recorded with the help of a stop watch, as well as the errors in the response. Generally, the tests were administered under good day light illumination. The arrangement of the colors was also in a manner that ensures the avoidance of regularity of occurrence.
Effects of the independent variables
The interference with the color stimuli, as is shown through the study of its data’s means and standard deviations reveals that there was a caused slight variability based on one’s gender with that of females increasing while the one for males decreasing slightly. On the other hand, the interference with the word stimuli showed a strong impact based on the habit developed in calling the words. The relative difference between the tests for this variable was the same considering that the coefficients of variability were the same too. However, the standard deviation increased in approximately the same ratio.
Suggested conclusions
In concluding, the authors basing on the research question suggests that the time difference in the reading of the words is the measure of the interference of the color stimuli when the words are read. The same applies to the word stimuli interference. Consequently, the response ‘to read’ is associated with the word stimuli, while the response like ‘to admire’, ‘to avoid’ are associated with the color stimuli (Braisby & Gellatly, 2012).
Variation in the stroop effect
I would contemplate a reduction in the number of the participants in the experiment to about four (two males and two females) having a mean age of 20 years. The investigation will use numerical instead of colors and words. The recording should be on the duration participants take in counting the mismatched digits, and not the alphabetical characters.
Assessing the stroop effect
Other measures may include testing for the capacity to direct attention and the determination of the mental vitality.
