THE STRUCTURE OF ABILITIES IN THE RETARDED

The ability structure in retarded women was studied on the same lines as with men (Kebbon, 1965). The women, 89 in number, were between 17 and 54, their IQ's between 40 and 90. Factor analysis was done of their scores on 16 tests measuring four factors—verbal, spatial-inductive, numerical and psychomotor. Comparison with the corresponding scores from 89 matched men and 92 normal men indicated that, in terms of these factors, retarded women have the same ability structure as retarded men, and that both have a similar structure to that of persons of average and superior intelligence.
