7 阅读理解 A lot of teachers hate doodlers(乱写乱画的人)during classes. "Pay attention!" Teachers will often warn doodling students, sure that they must be daydreaming. However, according to a recent study, doodling while listening to a boring lecture helps concentrate(集中)the attention: Andrade, a psychology professor in England asked participants to listen to a boring lecture. Half the participants were told to color in squares and circles freely on a piece of paper while listening to the lecture. The other half weren’t given a task. After it was over, the participants were asked to retell the lecture. Those given the doodling task (color in squares and circles) remembered 29 percent more information than the non-doodlers. Andrade said. "If someone is doing a boring task, like listening to a dull conversation, they may start daydream," said Professor Andrade. "Daydreaming distracts(使分心)them from the task, resulting in poorer performance. A simple task, like doodling, can stop them from daydreaming without affecting their performance at the task," he said. So the next time you"re doodling during a class, and you hear "pay attention", you can tell the teacher with confidence that you"ve been paying attention to every word． 1.
