Findings

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).
