In the mind again

British researchers who lied to volunteers that the decaffeinated coffee they were drinking had caffeine in it, noticed a significant improvement in performance and mood.
In a series of tests designed to measure mental performance, reaction times and mood, some even did better than volunteers who had consumed coffee with caffeine.
The results suggest that coffee’s pick-me-up powers may be at least partly due to consumers anticipating a caffeine “hit”.
Such is the expectation that caffeine in coffee will give them a boost that they feel its effects even when there is none, the researchers said.
It is well known that caffeine is a stimulant which works on the brain and can combat drowsiness and fatigue.
Some studies have suggested that three cups of a coffee a day can significantly reduce the risk of Alzheimer’s disease, possibly by triggering a chain reaction in the brain that prevents the damage done by the disease.
According to the British Coffee Association, British consumers drink approximately 70 million cups a day.
The study, by a team from the University of East London, involved 88 volunteers aged between 18 and 47 who were self-confessed coffee lovers, downing at least two cups every day.
The results are published in the journal Appetite
And how many other things do you do where the idea is what affects you rather than the action or experience itself?.
