A CLARIFICATION OF CROPLEY AND MASLANY'S ANALYSIS OF THE WALLACH‐KOGAN CREATIVITY TESTS

Abstract

In a recent article Cropley & Maslany (1969) examined the relationships among and between the Wallach–Kogan creativity tasks and the Thurstone Primary Mental Abilities tests in a sample of university students. A factor analysis yielded a general factor with moderate to substantial loadings for all of the tests in the battery. On this basis Cropley & Maslany concluded that complete statistical independence of the ‘creativity’ and ‘intelligence’ domains had not been established. The present paper attributes the Cropley–Maslany outcomes to a failure to rotate, and reports a Promax rotation of the Cropley–Maslany principal‐components solution. Such rotation yields a pure ‘creativity’ factor, and two ‘intelligence’ factors. Unlike the Cropley–Maslany principal‐axis factor loadings, the Promax solution is congruent with most of the evidence reported in other relevant investigations of the creativity–intelligence distinction.
