ananyo writes "From the Nature story: 'Scientists from Archimedes to Isaac Newton and Albert Einstein are said to have had flashes of inspiration while thinking about other things. But the mechanisms behind this psychological phenomenon have remained unclear. A study now suggests that simply taking a break does not bring on inspiration — rather, creativity is fostered by tasks that allow the mind to wander.' The researchers gave 145 students 2 minutes to list as many possible uses for an everyday object (the creative thinking task). Participants then either rested, undertook a demanding memory activity that required their full attention or engaged in an undemanding reaction-time activity known to elicit mind-wandering. A fourth group of students had no break. The researchers then set the students a second set of unusual-uses tasks and found those that had, in the interim, been set the undemanding task that encouraged mind-wandering performed an average of around 40% better than they did before. The students in the other three groups showed no improvement."
