A new study by John Kounios, professor of Psychology at Drexel University and Mark Jung-Beeman of Northwestern University indicates that basic differences in brain activity between creative and methodical problem solvers exist and are evident even when these individuals are not working on a problem. The study shows that greater right-hemisphere activity occurs even during a “resting” state in those with a tendency to solve problems by creative insight. This finding suggests that even the spontaneous thought of creative individuals, such as in their daydreams, contains more remote associations.
The study compared a methodical versus a more diffuse “aha” type of thinking.
