A new study conducted by researchers at the University of British Columbia concludes that coffee’s ‘stimulant’ effect only works on lazy people. What happens is that caffeine does not raise one motivation level.
“Every day, millions of people use stimulants to wake up, stay alert and increase their productivity — from truckers driving all night to students cramming for exams.”
The study, published in Nature’s Neuropsychopharmacology, looked at the impacts of stimulants on rats. When given stimulants, the ‘slacker’ rats that typically avoided challenges worked significantly harder when given amphetamines, while ‘worker’ rats that typically embraced challenges were less motivated by caffeine.
“These findings suggest that some stimulants may actually have an opposite effect for people who naturally favor the difficult tasks of life that come with greater rewards,” said Jay Hosking, who led the study. “The study also suggest that the amount of mental attention people devote to achieving their goals may play a role in determining how stimulants affect them.”
