From The Huffington Post:
Researchers from the University of California, Santa Barbara, found an association between daydreaming and creative problem-solving. Their study involved having participants first conduct an “unusual use task” — where they had to try to come up with as many weird ways to use an object as they could.
Then, the study participants did one of four things before doing the “unusual use task” again: perform a demanding task (where, presumably, their attention would be totally occupied by the task); perform an undemanding task; take a 12-minute break; or skip the 12-minute break and move right on to the task exercise again.
Researchers found that the only group who did better on the “unusual use task” the second time compared to the first time were the participants who completed the undemanding task. . . . [P]eople assigned to the undemanding task also reported high levels of daydreaming while completing this task.
