This study is primarily concerned with analyzing the most commonly used measures and its empirical findings of cognitive complexity. The first of these measures was used by Bieri(1955), in which he called "cognitive complexity." Bieri`s measure was obtained from responses to the Role Construct Repertory Test (RCRT) or Rep Grid devised by G. A. Kelley(1955). Unfortunately, due to both methodological limitations and the current lack of an underlying theoretical framework in which to place the data, research in this field is filled with contradictions. With respect to my own research (Son, 1977, 1982), I felt that the method was not tapping completely to understand the meaning of conceptual organization, It is necessary to measure both cognitive differentiation and cognitive integration. By considering the Personal Construct Theory of G.A. Kelley(1955), the most commonly used measures and the empirical findings of cognitive complexity was analyzed. A dual use of measures of both Differentiation and Integration is required.
