Caffeine and Studying

The study conducted by Hope L. Graven (2008) on the relationship between an individual's amount of caffeine consumption during his/her study session and the individual's study habits showed that the main effect of drinking caffeine on exam preparation was not significant There were participants, 20 male and 58 female college students (N=78), answered self-ratings on their personal consumption of caffeine as well as their study habits when preparing for a test/exam. It was hypothesized that the more caffeine a student consumes while studying, the more accurately his or her study habits would be labeled as 'unhealthy', as determined by the researchers. Unhealthy study habits were operationally defined as low scores on amount of time per study session, time(in days) when preparation began, and amount of information the participants believed they had retained. High scores on anxiety level were included in 'unhealthy' study habits. A Pearson correlation indicated no relationship between amount of caffeine consumed while studying and the individual's effectiveness of studying and preparation.

Marcus Credé and Nathan R. Kuncel (2008) in their research at the University of Albany said that Study habit, skill, and attitude inventories and constructs were found to rival standardized tests and previous grades as predictors of academic performance, yielding substantial incremental validity in predicting academic performance. The meta-analysis examined the construct validity and predictive validity of 10 study skill constructs for college students. They found that study skill inventories and constructs are largely independent of both high school grades and scores on standardized admissions tests but moderately related to various personality constructs; these results were inconsistent with previous theories. Study motivation and study skills exhibit the strongest relationships with both grade point average and grades in individual classes. They also said that Academic
