ABSTRACT

Two-dimensional representations of grids are commonly used in ideographic personality research. In Repertory Grid studies (Kelly, 1955), Principal Component Analysis (PCA) has been applied to that end (Rathod, 1981a; Slater, 1964, 1977), and is contained in programs such as INGRID. Applications of INGRID can be found in a variety of contexts

(e.g., Beail, 1985; Bonarius, Holland & Rosenberg, 1981; Fransella & Bannister, 1977; Slater, 1976). Programs similar to INGRID have been developed by Rathod (1981b), e.g., PAGAN, and by Tschudi et al. (1993), e.g., FLEXIGRID, the latter as part of a compilation of programs for grid-methodology.
