title: The factorial structure of the ITPA and WISC subtests in three diagnostic groups.
abstract: An image analysis of the ITPA and WISC Subtest Scores of three diagnostic groups was done. In two of the diagnostic groups, a regular classroom group and an LLD group, a general linguistic factor, a visual-motor factor, and a mediation factor appeared to emerge. A general ITPA factor, a general WISC factor, and an expressive factor were extracted from the mentally retarted group's data. Differences among the factors of diagnostic groups were observed and commented upon after a canonical correlation of factor loading matrices.
