English Cognitive Preference (CP) studies in science education have been met with several criticisms. One of these relates to response-format i.e. the ipsative nature of the scores, another to linguistic factors, in particular the possible causing of preferences for the Q(uestioning)-mode by matters unrelated to test modes as operationally defined. The present study used a horizontally split-half method of testing, converting the first half of the 40-item CP into an all-Q format, and leaving the other half in its traditional form (recall, principles, questioning and application). Intercorrelations between both parts were thus non-ipsative. Comparing subjects' CP-scores, mode-intensities and within-format correlations little or no differences were found. Moreover within and between-format correlations turned out to be essentially identical. Factor- and SSA-analyses confirmed the identical structures of both formats. It was concluded that ipsativity does not distort CP-data unduly, neither does the particular linguistic format of Q-statements cause substantial deviations from CP-patterns.
