Many people drink coffee or caffeine products in order to stay awake. Many people rely in their cup of coffee in the morning or throughout their day in order to function or to perform daily tasks. Rogers et al. (2012) discusses the various functions that caffeine has that can be beneficial and harmful to our psychological and behavioral. This study was interested to compare “the effects of caffeine in individuals who consume caffeine-containing products frequently with those who do not” (Rogers et al. 2012). Rogers study was influenced by Hollingworth study done in 1912 that focus on participant’s performance in mental and motor’ performance. As well as, Weiss and Laties (1962), study that indicated that there was no effect of caffeine on alertness

In doses between 65 and 130 mg caffeine improved performance, but in 390 mg coordination, performance was decrease. Many studies have come up with the conclusion that “frequent caffeine consumption provides no net benefit for alertness and, as a consequence, for performance of mental tasks requiring sustained attention” (2012). Although there has been disagreements, regarding the benefits of caffeine Rogers et al. (2012) decided to explore the relationship between the alerting and mental performance effects of caffeine. Rogers et al. (2012) hypothesized that caffeine would enhance motor performance by examining the interrelationships between the effects of caffeine on sleepiness, anxiety and mental alertness. I agree with the hypothesis that caffeine might enhance motor performance by allowing one to stay more awake and more focus to perform …show more content…
The IV was medium-high caffeine consumers and non-low caffeine consumers. The levels were high caffeine consumers who received placebo or caffeine and non-low caffeine consumers who received placebo or caffeine. The dependent level was the mental performance level. In the study, it indicated that medium-high caffeine consumers who received the placebo performed worst on their tasks throughout the day. In my opinion, the reason why they performed probably worse than low caffeine consumers is that medium-high caffeine consumers depend on caffeine in order to perform their tasks throughout the day. While the non-low caffeine drinkers do not really rely in caffeine. In this study, it was indicate that non-low caffeine consumers performed better if they received
