Need to get your brain in gear before proof-reading an important report for work? Then have some COFFEE first!
That’s the surprising conclusion of new research we read about in the Journal of Experimental Psychology. In a study, volunteers were asked to pop a capsule of caffeine before reading a short news story. Then, they were given five minutes to find and correct as many spelling and grammatical mistakes as they could find.
To make things interesting, the capsules contained random doses of caffeine - ranging from zero to 400-milligrams, which is about what you’d get from a 20-ounce cup of coffee.
The result? Believe it or not, researchers say the more caffeine volunteers had, the better they were at spotting errors! Why would that happen? Tad Brunye is a brain scientist who says caffeine seems to enhance performance in the part of the brain that helps us process and find “meaning” in words – whether they’re spoken or written down. And the good news is that you don’t need a lot of caffeine to notice a difference. In fact, his researchers saw improvements starting with the amount of caffeine you’d find in just half a cup of coffee.
