Description
Many studies have proven that caffeine has biological effects. Different procedures measure the effects of caffeine; one being via electroencephalogram. Electroencephalograms record the electrical activity of organs such. Studies have shown that under the influence of caffeine, EEG waves are manipulated; therefore this study seeks to evaluate the effects of caffeine consumption on EEG waves. The focus waves are alpha and beta waves which are more pronounced during a relaxed and non-aroused state and a waking, high alert state respectively. Because caffeine is a stimulant, we expect to see a decrease in alpha brain wave activity and an increase in beta waves. The experiment consisted of four trials. An EEG test was taken before as well as 20 minutes after caffeine consumption. Participants were not allowed to consume caffeine the morning of the experiment. During testing, participants closed their eyes for alpha testing and completed mental arithmetic with their eyes opened for beta testing. Our data was analyzed under the t-test method. The statistical significance is set to p<0.05. Alpha data includes p= 0.0932946, mean without caffeine: 2.01 μV and mean with caffeine: 4.045 μV. Beta data includes p= 0.03130103, mean without caffeine: 1.525 μV, and mean with caffeine: 3.02 μV. Our expected outcome proposed that alpha waves would decrease, and beta waves would be reinforced. Our data analysis revealed no effect of caffeine consumption on alpha waves (t=-2.430, d.f.=3, p=0.093). However, we did find statistical significance for beta wave data as caffeine did produce an effect (t=-3.833, d.f.=3, p=0.031).
