Abstract
2 groups of 10 children each were selected to form a mongoloid group and a normal group which were matched for MA although they differed markedly in IQ by virtue of gross differences in CA. Both groups were then studied in the learning of 5 different form discrimination problems. Mongoloid children required a greater number of problems to form a learning set than did normal children of the same MA. The author questions the use of the mental age as an adequate description of the learning ability and suggests that IQ as well as MA is an important predictor in many behaviors.
