Plymouth University researchers carried out memory tests on 40 volunteers, asking them to listen to a phone call and recall names and places. Doodlers performed 29% better than non-doodlers, the team found.
Experts said doodling stopped people from daydreaming, which was a more taxing diversion, and so was good at helping people focus on mundane tasks.
During the study, half of the volunteers were asked to colour in shapes on a piece of paper while they listened to a 2.5 minute telephone message. The other half were left to their own devices while they listened. Both groups were told the message would be dull, the Applied Cognitive Psychology journal reported.
Afterwards, both groups were asked to write down eight specific names and eight places mentioned. The doodlers on average recalled 7.5, while the non-doodlers only managed 5.8.
