Caffeine and Cognitive Performance

Medium Comparative Analysis Cross-reference

In a recent study conducted on the effects of caffeine on cognitive performance, researchers found that subjects who consumed moderate amounts of caffeine (around 200 mg, equivalent to two cups of coffee) exhibited improved reaction times and problem-solving abilities compared to those who did not consume caffeine at all. However, it was also discovered that excessive caffeine intake (over 400 mg, about four cups of coffee) led to decreased memory retention and heightened anxiety.

This study was consistent with previous research published in 2019, which indicated that low to moderate caffeine consumption might enhance cognitive function, while high consumption could impair it. Additionally, a survey conducted among college students revealed a significant correlation between caffeine intake and academic performance, particularly suggesting that those who consumed caffeine in moderation tended to achieve higher grades than their non-caffeinated peers.

Considering the comparisons made in both the recent study and prior research, which statement best summarizes the relationship between caffeine consumption and cognitive functions as outlined in the texts?

Caffeine universally improves cognitive abilities regardless of the amount consumed.

Moderate caffeine intake is associated with improved cognitive functions, while excessive intake may hinder performance.

No significant connection exists between caffeine consumption and academic performance.

All studies agree that caffeine has harmful effects on cognitive function.

Caffeine is the primary determinant of academic success for college students.
