"People may doodle as a strategy to help themselves concentrate," said study co-author Jackie Andrade, a University of Plymouth psychologist. "We might not be aware that we’re doing it, but it could be a trick that people develop because it helps them from wandering off into a daydream."
"Andrade’s findings, published in Applied Cognitive Psychology, are an interesting wrinkle on cognitive load theory: The mind has a limited amount of attention to give and, once occupied, stops processing other stimuli.
Cognitive load is exploited by magicians, whose verbal and physical flourishes distract from sleight-of-hand. It also explains why driving while talking on a hands-free headset is no safer than driving while holding a phone. And it could be the reason why doodling is so much better than daydreaming."
