The hypothesis presented for this study was that there would be a significant
correlation between cognitive abilities and caffeine consumption. The research question
that was chosen for my study is: Does caffeine affect human cognitive abilities? The
predicted hypothesis is that caffeine influences an individual's cognitive capacity and
ability to execute tasks more efficiently. The null hypothesis is that there is no difference
in the effects of caffeine between individuals who have consumed it and those who have
not.
17 participants provided reliable responses for the entire survey for analysis to obtain
results. The survey results presented a significant correlation between the two variables
(caffeine consumption and cognitive abilities), thus accepting the hypothesis that was
presented.
Previous Literature
The outcomes of my research differed significantly from the majority of the
literature examined on this subject. Most of the studies reviewed, although not all in
agreement, suggested a beneficial relationship between the two factors. Previous studies
have highlighted the impact of high caffeine consumption on individuals, primarily
focusing on the physical consequences rather than the psychological and emotional
aspects. For example, the study by Sanjakdar et al. (2019) found that acute (short-term)
caffeine consumption had no noticeable effect on motor or cognitive outcomes after a
traumatic brain injury (TBI).
