Caffeine after learning session may boost long-term memory

3 years ago

You likely already know that caffeine can boost certain cognitive skills, like processing speed and attention. But new evidence points to the idea that it also boosts long-term memory when taken after a learning session.

A study from Johns Hopkins looked at the effects of caffeine on 18- to 30-year-olds.

They created two groups, both of which looked at a number of photos and were asked to identify if the objects were indoor or outdoor objects. Right after the task, one group was give a caffeine pill and the other was given a placebo.

The next day, the groups were shown the same photos and new ones. They were asked to tell if the items were indoor or outdoor again, but this time they were asked if each photo was old, new or similar to a photo the day before.

The participants who took caffeine were better at identifying which new photos were similar to the previous day.

The researchers tried different levels of caffeine and found that 200mg produced the best results.
