This can be explained by two (2) theories the first being the speed of processing theory which assumes that interference in reading words occurs due to the fact that words can be read at a first speed as compared to reading colours. The second theory is the selective attention theory which on the other hand assumes that interference in naming colours entirely requires specific attention as compared to reading words. To study this effect, a sample of 276 participants was selected. The research study involved the researcher asking the participants (276 of them) to mention name words and non-words from two (2) different sets printed using different colours. The words in the two (2) lists were not consistent to allow for randomization and were not of the same length according to Stroop’s recommendations. Further, the colours used were different although the number of words was the same in both lists. The correctly named words and non-words were recorded for comparison. The results indicate that, the mean difference between colour words and non-sense words was found to be significant at 5% level of significance [Z = -13.318, P = 0.000, p nonsense words and c colour words = nonsense words From table 2, 15 participants had colour words less than non-sense words, 256 participants had colour words greater than non-sense words while 5 participants had colour words equal to the non-sense words. Table 3: Test Statistic- Wilcoxon Signed Ranks Test Colour words - Nonsense words Z -13.318 Asymp. Sig. (2-tailed) .000 The mean difference between colour words and non-sense words was found to be significant at 5% level of significance [Z = -13.318, P = 0.000, p5.440. 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 colour and non-sense words. From the non-parametric test results, there is significance difference between the mean number of colour and non-sense words at 5% level of significance. The mean difference between colour words and non-sense words was found to be significant at 5% level of significance [Z = -13.318, P = 0.000, p Read More
