How do scientists capture the euphoric flights of creativity? The answer to this question led to surprising, some might say shocking, evidence of the human brain’s capacity for invention, and quite possibly reinvention. The cerebellum, long considered a drudge-like region of the brain, performs its own unique dance in the creative process, say researchers from Stanford’s School of Medicine and the d.school (Hasso Plattner Institute of Design). Their new study also suggests that trying too hard can block, rather than increase, the inspirational flow.
You can’t exactly command people to alight on an original thought or two while they lie on a cold, hard MRI bed. Considering this problem, Dr. Manish Saggar, a co-author of the study and instructor at the d.school, figured it would be best to simply trick people into revealing their imaginations. With this in mind, he borrowed an idea or two from Pictionary, a game that requires players to draw instead of say words, when designing his experiment.
After selecting a few verbs, Saggar and his colleagues tracked the brain activity of 14 men and 16 women who drew the words while lying in an MRI chamber. For each word, participants improvised an illustration in the allotted time of just 30 seconds — time enough for a decent brain scan but not enough time for anyone to get bored. For comparison, participants also drew a quick zigzag line, an action requiring fine-motor control but minimal creativity. When finished, participants rated the difficulty of drawing each word.
When the experiment concluded, the researchers gathered all the drawings and rated each on five-point scales of appropriateness (the accuracy of depiction) and creativity (elaborateness and originality of design).
Finally, the researchers sat down with drawings and scans and began to compare and discuss, review and analyze. Meanwhile, the hands on the clock spun round and round and the number of coffee rings increased beside the half-eaten sandwiches littering the desks.
