According to a recent report on the US website MSNBC, an interesting study has been published in the journal Experimental Psychology. The researchers recruited a group of college student volunteers and asked them to randomly take a capsule containing 100, 200 or 400 milligrams of caffeine and no caffeine at all. 45 minutes after taking the capsule, ask them to read an article, find out the spelling and grammatical errors in it, and correct them. It was found that people who consumed more than 200 milligrams of caffeine had the best ability to detect and correct grammatical errors compared with those who did not consume caffeine, and the more caffeine they consumed, the more effective they were. Caffeine makes our brains more "alert", making people more "perceptive", researchers say. However, for those "coffee users" who often drink coffee, they need to take more than usual in order to have an effect.
