This is a summary from Technorati:
Researchers divided kids [four-year-olds] into three groups: one group of children watched Caillou, a slower-themed show on public television, the second group was given crayons and paper to draw with, while the third watched SpongeBob. Afterward, the group who watched the yellow square guy wasn’t able to follow rules as well or to delay gratification as easily. (Interestingly, the group of kids who watched Caillou and the group who drew pictures performed at pretty much the same level.)
Even without a formal study, some writers believe that watching television can affect the creative process. Viewing a TV show is largely a passive process—it’s about taking in information. We wonder: Does watching a fast-paced TV show “echo” for you when you begin writing?
Here’s what one Writer’s Relief staffer says:
Say I’m planning to write for one hour. If I watch TV in the minutes before that hour, my sense of creativity is decreased—as opposed to if I do something else, like cooking, knitting, or meditating.
