The primary literature article is titled, Dose–response study of caffeine effects on cerebral functional activity with a specific focus on dependence. This article consists of many parts including an abstract, introduction, materials and methods, and results. The articles aim is to explain the physiological functions of caffeine and how it affects the brain. The language used in this article is very specific and scientific. It consists of very precise word choice and both quantitative and qualitative information. In the introduction, this article mentions that the average daily caffeine consumption for all adult consumers and from all sources reaches 2.4–4.0 mg/kg for a 60–70 kg subject in the United States, UK and Canada (Nehlig and Boyet, 2000).

One hundred and two (51 males and 51 females) nondependent caffeine users who consumed less than 300 mg of caffeinated beverages per week participated in a four experimental session study. Each participant was given four drug conditions in capsule form (placebo, 50, 150, or 450 mg of caffeine), each in random order, with three days intervals, between 9 a.m. and 1 p.m. Before and after each drug administration, the participant’s physiological data (heart rate, blood pressure) was measured.

This experiment studied the effects of caffeine on the reaction time of a number of students. It was done with 12 individuals who all selected their own source of caffeine to use for the testing. The three main caffeine sources were V energy drink, coffee and red bull. The reaction times of these students were recorded before and after drinking the caffeine in order to obtain results on the effect that caffeine had on the individual. This was done by using an online reaction test where students were to click on a button each time the green traffic light appeared. The results indicated significant differences in the reaction times of the students’ pre and post caffeine intake. Therefore, the experiment showed that caffeine did have an impact on the reaction time of the student after consuming caffeine. This report allows comparison of the mean scores of the 12 groups using tables and graphs to clearly indicate the differentiation of each result.
