In an attempt to see whether one can differentiate the highly creative from those of lesser creativity on the basis of hemispheric processing, 100 people were presented with a battery of creativity tests, control cognitive tests, and tasks known differentially to engage the left and right cerebral hemispheres. Compared to those of lesser creativity, the highly creative participants exhibited a greater tendency habitually to employ the right hemisphere in task solution and a pattern of cerebral lateralization marked by a greater segregation of verbal functions to the left hemisphere and bilateral representation of a nonverbal, melodic function. The success at predicting creativity level on the basis of hemispheric task performance was impressive, and was observed even when general intellectual abilities were equated in the high and low creative groups.
