Seems drawing while listening actually helps doodlers remember details.
In a study conducted by England's University of Plymouth, participants were asked to listen to a 2.5 minute tape giving several names of people and places, and were told to write down only the names of people going to a party. Half were asked to draw shapes while listening.
English researchers found doodlers recalled on average 7.5 names of people and places compared to only 5.8 by the non-doodlers. Scientists say they think doodling actually keeps people from daydreaming and helps their brains stay on track.
