ABSTRACT
The structure and measurement of human cognitive abilities as a function of gender and age. Although there is strong evidence for measurement validity across gender, males and females exhibited mean differences in performance on some of the measures. There appear to be several quantitative differences as a function of age, but these may not be interpretable because there is reason to question the measurement validity across the two age groups. The empirical suggestion that age should be taken into account leads to the idea that additional variables should be considered as well. The measurement structure of the WJ-R is similar across gender, but this does not imply that other forms of bias would not result from using such test batteries. The lack of consistent findings in earlier research may be due to the absence of a developmental approach to understanding gender differences in cognitive abilities.
