An anonymous reader quotes a report from Technology Networks: According to a popular view, creativity is a product of the brain’s right hemisphere — innovative people are considered “right-brain thinkers” while “left-brain thinkers” are thought to be analytical and logical. Neuroscientists who are skeptical of this idea have argued that there is not enough evidence to support this idea and an ability as complex as human creativity must draw on vast swaths of both hemispheres. A new brain-imaging study out of Drexel University’s Creativity Research Lab sheds light on this controversy by studying the brain activity of jazz guitarists during improvisation. The study, which was recently published in the journal NeuroImage, showed that creativity is, in fact, driven primarily by the right hemisphere in musicians who are comparatively inexperienced at improvisation. However, musicians who are highly experienced at improvisation rely primarily on their left hemisphere. This suggests that creativity is a “right-brain ability” when a person deals with an unfamiliar situation but that creativity draws on well-learned, left-hemisphere routines when a person is experienced at the task. “[W]hen a person is an expert, his or her performing is produced primarily by relatively unconscious, automatic processes that are difficult for a person to consciously alter, but easy to disrupt in the attempt, as when self-consciousness causes a person to ‘choke’ or falter,” the report says. “In contrast, novices’ performances tend to be under deliberate, conscious control. Thus, they are better able to make adjustments according to instructions given by a teacher or coach.”
“Recordings of brain activity could reveal the point at which a performer is ready to release some conscious control and rely on unconscious, well-learned routines. Releasing conscious control prematurely may cause the performer to lock-in bad habits or nonoptimal technique.”
