Many people drink coffee or caffeine products in order to stay awake. Many people rely on 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 functioning. This study was interested in comparing the effects of caffeine from those who drink caffeine products regularly with those who do not (Rogers et al. 2012). Rogers study was influenced by the Hollingworth study done in 1912 that focused on participant’s performance on mental and motor tasks. Weiss and Latie’s (1962), study indicated that there was no effect of caffeine on alertness in non-consumers.

Nevertheless, in my opinion the reason why the high-medium caffeine consumers performed worst was that they have become too dependent on caffeine and show withdrawal signs. Those who consume too much caffeine products tend to become tolerant to caffeine and feel the need to consume more to function. However, after this study it was concluded that caffeine does not really have many benefits when it comes to mental alertness but it can increase motor performances. I think the methods the researchers used were good because they provided a self-report questionnaire and a computer-based task to test the benefits that caffeine can provide. Also because they provided different ways to collect data by providing a control group. Both levels had a placebo group which tells us how each group performed with or without caffeine. The fact that the participants were aged between 18 and 62 years was great because it provided a population that probably consumes more caffeine due to work and school and I am assuming that the majority of the participants were college students since the study was approved by the University of Bristol’s psychology
