Caffeine is found in tea and coffee. The physiological effect of caffeine increased heart rate. Caffeine excites the receptors within your heart to work faster by blocking the enzyme phosphodiesterace. Heart rate is kept normal by these phosphodiesterace. Once phosphodiesterace is blocked, there is no longer effective and your heart rate increases. The psychological effect of caffeine is increased alertness. It helps you to feel more awake and less tired, so it is used for medication to treat drowsiness. Caffeine’s psychological effect is that caffeine mimics the neurochemical called adenosine. Caffeine mimics the shape, size of the adenosine and enters the receptor without stimulating them. Then caffeine blocks the receptors and allows the other stimulants such as dopamine and glutamate to work freely while the caffeine holds the

515) This testing showed that when a person consumes large quantities they in effect are not good for testing purposes unless of course the test is for withdrawal effects. Their perspective was, “We hypothesized that caffeine would increase ratings of arousal, stimulation, and anxiety and decrease ratings of fatigue, and that caffeine would improve performance on a visual vigilance task.” (Childs and de Wit, 2006, p. 515) This last task was more along the line of observing something then recognizing it when it is recurring in the test. The literature review being presented are a collaboration to present the hypothesis that there is a casual effect between moderate amounts of caffeine consumed and cognitive
