abstract

  • This study compared scores on the Wechsler Intelligence Scale for Children-Revised, Peabody Picture Vocabulary Test, and Slosson intelligence test for 64 students (45 boys, 19 girls) who ranged in age from 7–3 to 13–2. Mean IQ on the Peabody was significantly higher than the mean IQ on the Wechsler Intelligence Scale for Children-Revised and on the Slosson. The mean IQs were 95.0 for the Peabody, 89 0 for the Slosson, and 87.8 for the Wechsler Full Scale, with standard deviations of 12.3, 11.7, and 7.0, respectively. Highest correlations of IQs were between Verbal Scale of the Wechsler and the Slosson (.81) and between the Verbal and Performance Scales of the WISC-R (.73).
