Coffee increases your problem-solving ability and your focus, a new study confirms. But it doesn’t make you more creative – so all writers and artists downing cups in the hopes of finding inspiration might be better off with a soothing cup of tea, Metro reports.
For the study, 80 volunteers were randomly given either a 200mg caffeine pill, equivalent to one strong cup of coffee, or a placebo. They were then tested on standard measures of convergent (problem solving) and divergent (the generation of ideas) thinking, working memory and mood. Caffeine was shown to improve convergent thinking in the study, while consuming it had no significant impact on divergent thinking, Metro informs.
