Creative thinking abilities and hemispheric asymmetry in schizotypal college students

Two groups of college students that scored high (N=25) and low (N=60) on a schizotypal personality index based on the Perceptual Aberration, Magical Thinking, and Schizotypal Personality Scales, were tested for hemisphericity using a dichotic listening task and completed the Torrance Test of Creative Thinking. The schizotypy scales correlated with high scores on the nonverbal portion of the creativity tests and with a left ear preference to dichotically presented verbal stimuli. The Torrance Test of Creative Thinking did not correlate, however, with hemispheric asymmetry. These results clarify the relationship between schizotypy and creating thinking abilities but fail in establishing the role of hemispheric asymmetry in the production of creative thinking ideas.
