Effects of Caffeine Consumption in College Students

Caffeine is the most commonly consumed stimulant in America, and it provides several psychological benefits including increased alertness and concentration. The purpose of this study was to determine whether college students identify caffeine as something that helps boost their level of concentration. Participants were tested on a hand-eye coordination task, while we recorded their accuracy and speed. Participants were then asked to drink 12oz can of a soda (non-energy drink or coffee) and repeat a similar hand-eye coordination task. Upon finishing these tasks, participants were then asked a series of self-report questions about their self-efficacy regarding productivity before and after ingesting the caffeine. We hypothesized that students’ performance was better (more accurate and faster) after ingesting the caffeine.
