| Abstract: | The purpose of the present study was to test the factor structure of the McCarthy Scales of Children's Abilities in preschool children. Seventy-two boys and 69 girls between 4 and 5 years of age were tested. A factor analysis was carried out by means of the principal components method with varimax rotation. The existence of the Verbal factor and of the Perceptual-Performance factor was confirmed. The Quantitative and Memory factors appear undifferentiated. As far as the subtests which make up the Motor scale are concerned, they do not constitute a single factor. The significance of these findings is discussed. |
