Factor Analysis of the Test Performance of Institutionalized EMR Children on the WISC and ITPA.
Alston, Herbert L.; And Others
The WISC (Wechsler Intelligence Scale for Children) and ITPA (Illinois Test of Psycholinguistic Abilities) test scores of a group of 54 educable mentally retarded (EMR) students (mean age l2 years) were factor analyzed to determine the extent to which the WISC and ITPA measured common factors. Of the four factors obtained, nine of the ten ITPA subtests and none of the WISC subtests loaded high on factor 1 (general ITPA). Factors 2, 3, and 4 were primarily defined by the various WISC subtests and were interpreted as a verbal factor, a visual-performance factor, and a vocabulary factor respectively. For EMR Ss, the ITPA did not measure the same factors measured by the WISC, nor did it appear to measure distinct cognitive abilities. (Author/SB)
