Abstract: This paper discussed the possibility that intelligence structure might be changed with individual differences such as ability and age. The cognitive-differentiation hypothesis indicates that higher-ability individuals have ‘more’ intelligence and the effect of g factor descends with IQ increasing in their intelligence structure. The age-differentiation hypothesis states that from childhood to early maturity, the effect of g factor decreases with increasing age in cognitive ability. However, from early maturity to late adulthood, an increase in the importance of g factor and a decrease in the number and importance of the remaining abilities are predicted. Future researches in this field should resolve the problem of measurement & assessment instruments, and extend the range of subjects’ ability and age
