Find a spelling error while reading the paper type is sometimes annoying, some people can be so chatty. A cup of coffee can make it more talkative, because the eye so much more sensitive when it finds a spelling error type.
Effects of caffeine on language skills revealed in an experiment at Tufts University, which involved three groups of students. Some were given coffee with caffeine levels high, some low-yield and the rest is just blank or given a placebo drink.
All students who become participants in the study were given a reading book, and then asked to report if there are spelling or grammatical errors. This task is somewhat like the job of an editor, which is researching typos and incomplete sentences.
The result is predictable, the group of participants who received high doses of coffee found at most errors in the same book. Participants who received low doses of coffee also found more errors than participants who drank the placebo.
“Alertness after drinking coffee can improve the brainpower required to do the editing language or find fault,” said Tad Brunye, PhD, a neurology expert who led the study, as quoted from Menshealth.com, Tuesday (11/08/2011).
Brunye added, the effect of caffeine can increase the sensitivity to errors of written language in the levels of 20 mg / day. At regular brewed coffee that is not extracted with high-pressure engine, this level is approximately equivalent to a medium-size cup of coffee.
In addition, the process of absorption of caffeine into the blood also determines the effect. According Brunye, it took about 30-25 minutes after a person drinks coffee to the eye and brain to be more careful in finding a typo or other language errors.
Dr. Woolsey suggests, when coordination is necessary capabilities should not rely too much on energy drinks. Adequate sleep is much healthier to overcome drowsiness, without reducing the brain’s ability to coordinate and maintain concentration.
Professor Sigmon said it was important to increase understanding of this difference, because this could be the key differences in susceptibility or resistance in drug abuse.
The scientists believe that one’s response to d-amphetamine also showed how they would react to drugs such as cocaine because it has the same effect.
This study is the first prospective study of caffeine in predicting the positive subjective effects of other drugs.
“Although this data does not mean that all coffee lovers at risk to become addicted to cocaine, but this study suggests that individuals vary greatly in subjective and behavioral responses to psychomotor stimulant,” concludes Professor Sigmon.
