Neurophysiologically, humans are sight (visual sense) dominant. thirty to forty percent of our cerebral cortex is devoted to vision, as compared to 8 percent for touch or just 3 percent for hearing (auditory sense)

After spending all that time on the research then by all means modify the hypothesis or aim by reporting such. for example the findings did not bring forth what was expected but brought about different yet interesting findings worth exploring so the hypothesis is changed to reflect this new findings.
