Additionally, a short comprehension test of visual figures was done beforehand in order to validate the responses given. The findings of the article showed that the people of European decent had failed on viewing the lines as the same length on the Müller-Lyer illusion than the non-European samples. Comparing the European sample with the sample from Illinois showed that they were similar in the rate of failure of the Müller-Lyer test. The Sander Parallelogram on the other hand showed different results. The European and non-European had similar results in the Sander Parallelogram with the European having only a slightly higher fail rate. These results indicate that while the biological basis on how these cultures view the illusion is the same, the success or failure is a cross-cultural effect. The article suggests the reasoning of the finding is more systematic in
