From the paper "The Factors that Influence the Stroop Effect" results, 276 participants participated in the study and in both cases; the minimum number of none-sense and color word named was 17 words. The maximum number of color words were 75 with M = 36.5 and SD = 8.442 while the maximum non-sense words named were 60 with M = 27.41 and SD = 5.440. The amount of variation in naming color words is high as compared to non-sense words 8.442> 5.440. Both variables are not normally distributed and thus parametric tests (in this case t-test) could not be used.
Non-parametric test; Wilcoxon Test was used to test for significance in the mean difference of the number of colors and non-sense words. From the non-parametric test results, there is a significant difference between the mean number of color and non-sense words at 5% level of significance. It is evidently clear from the discussion that the mean difference between color words and non-sense words was found to be significant at 5% level of significance [Z = -13.318, P = 0.000, p< 0.05].
This means that participants named more color words than non-sense words. The results are a manifestation of both Stroop and Glassberg et al. on how the human brain handles conflicting materials and that completion of a certain task is affected by the dominant area of the brain which response to other functional areas. Further, Glassberg’ s assertion of delay in the procession of the color of the word is true. Research LimitationsThe research findings are limited in that there is no proof that the sample used is not representative of the whole population such that the findings can be generalized to fit the whole population.
Further, there is a need for all ethical considerations to be put into considerations. Issues to do with; Data/information security-confidentiality; Financial benefits to the participants; Research benefits; Protection of the participants; andJustice in the sample selection.
