Abstract
Caffeine, whether taken in the form of coffee, tea, or soft drink, is a powerful and ubiquitous psychoactive drug that enhances alertness but at the cost of increased tension at higher levels. It facilitates cognitive performance on tasks that require sustained attention, particularly for fatigued participants, but has more complicated effects for complex cognitive tasks. As with many things, moderation is recommended.
