Cognitive styles gained prominence in organizational behavior and management literature during the last decades. Researchers studied cognitive styles in relationship to various concepts and from various points of view. Different authors developed their own instruments of assessment to identify differences in cognitive styles. However, this theoretical and empirical pluralism makes the field of cognitive styles rather confusing and leads to inconsistent measurement results. Several authors try to create order in the diverse field by integration of the different theories. With this state of affairs in mind, the purpose of this article is twofold. Firstly, we attempt to demarcate and define succintly the field of cognitive style research. Secondly, we want to present our research on cognitive styles, which led tot the development of the Cognitive Style Inventory (CoSI). We are currently finalising the validation and cross-validation of our self-report questionnaire. The theoretical background of the questionnaire is presented. Because of the usefulness of the cognitive style concept for organizations, clarification of the research field and the development of a useful questionnaire to measure individual differences in cognitive styles are necessary
