Factor Analytic Study of the Embedded Figures and Rod and Frame Tests

Abstract

154 first-year university students were administered marker tests for Guilford's Factors of Convergent Production of Figural Transformations, Cognition of Semantic Units, and Cognition of Figural Systems as well as Witkin's Embedded Figures Test and the Portable Rod and Frame Test. Scores in the test battery were factor analyzed to determine the equivalence of different measures of psychological differentiation. Results of the analysis indicated that the Embedded Figures scores correlated (—.52) with Convergent Production of Figural Transformations, whereas the Portable Rod and Frame scores did not load on any of the factors extracted.
