The work followed 44 people who didn’t have coffee for a day. Afterward each person was given a pill. Half took placebos and half were given caffeine.
Scientists found people who took the caffeine pills were an average of 10% better at remembering pictures and patterns.
Nature Neuroscience reports one researcher summed up the findings like this, “what I've taken from this is that I should keep drinking my coffee."
"Our study suggests there's a real learning and memory benefit," he continued.
Gizmodo points out there is a “correct” amount of caffeine.
It seems about two espressos makes the biggest difference. Anything more or less and the results were less dramatic.
While many have long said caffeine can boost brainpower others say this study is flawed because of the small number of subjects.
Meanwhile another group just finished one of the largest cognitive-training studies in history.
Reuters says 3,000 upper age adults were given brain exercises to do. Ten years after that study those involved still showed higher function in reasoning, processing, and memory than those who didn’t.
