bjcg: A new study in Applied Cognitive Psychology tells us that doodling might help concentration, as opposed to hindering it. The basic theory is that doodling takes up very little brain bandwidth, but it might prevent us from zooming off on wild flights of fancy — which would require far more brain power. In the experiment, 40 people listened to a list of names of people and places. After that, they were asked to write down the names they could remember. Half the subjects were asked to doodle (filling in shapes on a piece of paper); the other half not. The doodlers remembered one-third more names than the non-doodlers. So, next time your boss catches you doodling in a meeting, just tell him or her: “I did it because of science.”
