Brand variation in the stimulatory effect of coffee on the productivity of graduate teaching assistants Jim Heffernan Bio 187 June 11 th , 2097 Abstract : While the stimulatory effects of coffee are widely recognized and accepted, it is not currently known whether commercially available brands of coffee differ in their ability to enhance the productivity of graduate teaching assistants. In order to determine whether or not variability in stimulatory power exists among coffee brands, we measured the grading productivity of graduate student teaching assistants after consumption of several brands of coffee. We found that considerable variation in stimulatory effect existed among coffee brands, with graduate students drinking Sanka and Fry’s brand coffees grading far fewer papers (5.2 and 6.3 papers/hr) than graduate students who were provided with recently air-lifted and freshly ground Javanese coffee made using a French press (Brand X). One potential explanation for this pattern is that these brands vary in chemical characteristics such as caffeine concentration, but an alternative is that the subjects responded psychologically based on their perception of the coffee’s likely effectiveness. Future research is needed to determine the relative importance of psychological and physiological processes in the stimulatory effects of coffee.

Introduction Throughout much of the world, people in all walks of life consume coffee as a matter of course during their morning routine, as well as to remain awake in the unlikely event that they need to stay up past bedtime. The latter use is particularly common among graduate teaching assistants, who are obligated to grade thousands and thousands of homework assignments,
