The Relationship Between Nonclinical Schizotypy and Handedness on Divergent and Convergent Creative Problem-Solving Tasks

Previous research indicated a relationship between hemispherical dominance, the extent of schizotypal tendencies, and creativity. Little research has been conducted to assess the degree of schizotypy in nonclinical samples. The aim of this study was to determine the extent to which measures of multidimensional schizotypy and predominant handedness could predict measures of creativity, as assessed by both divergent and convergent tasks. One hundred and twenty-six participants participated in a quasi-experiment involving tests of predominant handedness, schizotypal tendencies, and divergent and convergent thinking. Results suggest that individuals who scored high on a test for schizotypal tendencies performed better on divergent problem-solving tasks, as opposed to low scoring individuals who performed better on convergent problem-solving tasks. Furthermore, results suggest that there was relationship between handedness on divergent and convergent thinking. There was, however, a relationship between handedness (right hemisphere) on the degree of schizotypal tendencies with left-handed individuals demonstrating greater schizotypal tendencies.
