Abstract Details

2014, BA, Kent State University, College of Arts and Sciences / Department of Psychological Sciences.
The present study examined the effects of sleep quality and acute coffee consumption on sustained attention. Seventy-five college students participated in the 2x2 mixed design experiment, with beverage type (8 ounces water vs. coffee) as the within subjects factor, and sleep quality (high vs. low sleep quality, assessed by the Pittsburgh Sleep Quality Index) as the between subjects factor. Participants completed a continuous performance test to assess sustained attention and vigilance performance on two separate days after consuming coffee or water, in a counterbalanced design. Statistical analysis revealed no main effect of sleep quality on sustained attention. In contrast, there was a main effect of beverage condition on sustained attention, with fewer errors of commission following coffee consumption compared to water. There was no interaction between sleep quality and beverage condition on sustained attention. Although results failed to demonstrate an interaction between sleep and caffeine, findings support prior work demonstrating that caffeine is a central nervous system stimulant that has a positive effect on sustained attention. Furthermore, the positive effects of coffee on sustained attention appear to occur regardless of an individual's quality of sleep.
