dc.description.abstractPrior caffeine research has examined the effects of caffeine on performance using simple, lower-level cognitive tasks. The present study extended this work to investigate the effects of caffeine on performance and self-report mood measures during execution of a complex cognitive task. In a between-subjects design, 116 participants were administered either caffeinated or non-caffeinated chewing gum. Results showed higher fatigue and negative affect (NA) levels and lower positive affect (PA) and task performance levels in the placebo condition. These findings replicate prior findings on mood effects of caffeine; also, they extend the limited results on performance effects of caffeine by demonstrating moderate support for improved complex cognitive task performance after caffeine intake. Furthermore, these results show the efficacy of gum for caffeine administration in research.en_US
