“I started looking at jazz musicians playing the blues as a way to understand how the creative brain emerges from a neuroscience perspective,” said Charles Limb, associate professor of Otolaryngology-Head and Neck Surgery at John’s Hopkins University.
When musicians go to an improvisation, the brain switches, Limb said, and the lateral prefrontal lobes responsible for conscious self monitoring became less engaged. “Musicians were turning off the self-censoring in the brain so they could generate novel ideas without restrictions,” he said. Interestingly, the improvising brain activates many of the same brain centers as language, reinforcing the idea that the back and forth of improvisation between musicians is akin to its own language.
The same principle applies to something like writer’s block. “When you’re trying so hard to come up with ideas you can’t do it, you can’t force it,” Limb said. “Then at another time, some flip switches and you’ve got this flow going on, this generation of ideas.” When the stakes are higher and the brain is actively over-thinking something, it can interfere with processes that have become routinized, causing behavior or performance to suffer.
Luckily, creativity isn’t an unknowable, mystical quality. It can be developed. “You have to cultivate these behaviors by introducing them to children and recognizing that the more you do it, the better you are at doing it,” Limb said. The problem is a lot of kids don’t get much unstructured time either in school or out of it. School is often based on right or wrong answers, leaving little room for students to come up with ideas that haven’t been taught to them before.
“It doesn’t have to be so directed all the time,” Limb said. “We’ve taken a lot of the joy out of things that used to be joyful.” Even a lot of music lessons have become about the discipline of learning to play well, not the joy of creating the music. Children should have part of every lesson reserved for improvisation and free form play, Limb said. The same could be said for free play on the playground and experimentation with new ideas in the classroom. Unprogrammed time is necessary for students to practice using their creativity.
