Coffee Boosts Mental Performance? Not Really, Says Study
Coffee credits to be a most popular beverage, as a number of people seek the drink to start their day across the globe. In Britain alone, no less than 70 million cups of coffee are sipped every day.
However, a recent research has claimed that the usual perception, which appreciates coffee to boost mental performance throughout the day, is nothing more than a psychological state. To conclude the findings, a team of British experts have analyzed around 88 volunteer coffee lovers aged 18-47.
During the study course, the subjects were grouped under two groups where the first group was served with caffeinated coffee but told that the beverage has been decaffeinated whereas rest of the volunteers were offered decaffeinated with a tag of caffeinated coffee.
Afterwards, they carried out a color test and observed that participants who had an illusion to drink caffeinated coffee have performed excellent while performing the tests and concluded that its caliber is due to belief.
"The findings suggest the expectation of having consumed caffeine confers an enhancement on sustained attention that is at least comparable, and perhaps superior to, the effects of caffeine", explained researchers.
