Factor Structures of Retarded and Nonretarded Children On Raven's Progressive MatricesResearch Institute for Educational Problems Cambridge, Massachusetts
Research Institute for Educational Problems Cambridge, Massachusetts Item responses of two samples of normal and educable mentally retarded (EMR) children on Raven's Coloured Progressive Matrices were submitted to a principal components analysis and varimax rotation. Four factors were obtained which corresponded to readily identifiable problem types. The factor structure for both retarded and nonretarded subjects was replicated by an independent sample. Comparability of factor structures of normal and retarded subjects indicated the factorial invariance of this test with children of different IQ levels.
