Extent of psychological differentiation and creativity

Among the extensive array of studies relating Witkin's construct of psychological differentiation to many psychological functions and variables, none seem to have adequately tested its relationship to creativity, although these two variables have personality traits and development characteristics in common and require similar skills for effective performance. Eighty-five male high school students were separated according to Embedded Figures Test, and the extreme groups tested for creativity by eight factorially pure tests developed by Guilford, and by Schaefer and Anastasi's Biographical Inventory. Statistical procedures included analysis of covariance, analysis of variance, and a matrix of intercorrelations. With intelligence controlled, field-independent persons performed significantly better than field-dependent persons on measures of visualization, spontaneous flexibility, adaptive flexibility, and creativity in mathematics and science but not significantly better on the other six creativity tests.
