The present study investigates the factor structure of the Cognitive Style Index (CSI), comparing the unitary, bipolar continuum of intuition-analysis, the theory upon which the CSI is predicated, with the two-factor theory of cognitive style. We conducted both confirmatory and exploratory factor analyses on data from a sample of 222 American university business students. There was a lack of fit for the unifactorial model. Our results suggest the instrument is tapping multiple dimensions of cognitive style, the implications of which are discussed. (Contains 3 tables.)
