认知能力个体差异在整个生命过程中的稳定性是人类认知衰老研究的基础。很少有关于认知能力的研究对同一个人在青年和老年时期进行测试。我们对11岁和90岁的同一个体（1921年洛锡安出生队列，N = 106）进行了同样的智力测试，检验了个体差异的稳定性、并发性和预测有效性。11岁与90岁Moray House Test成绩的相关性为。54(。67当修正范围限制时)。这是一个很有价值的基础，可以用来估计老年人的认知能力差异在多大程度上是由终身稳定的特征和整个生命过程中认知变化的原因造成的。在11岁和90岁时，Moray House测试结果与金标准认知测试结果具有较强的同步效度和预测效度。
As a foundation for studies of human cognitive aging, it is important to know the stability of individual differences in cognitive ability across the life course. Few studies of cognitive ability have tested the same individuals in youth and old age. We examined the stability and concurrent and predictive validity of individual differences in the same intelligence test administered to the same individuals (the Lothian Birth Cohort of 1921, N = 106) at ages 11 and 90 years. The correlation of Moray House Test scores between age 11 and age 90 was .54 (.67 when corrected for range restriction). This is a valuable foundation for estimating the extent to which cognitive-ability differences in very old age are accounted for by the lifelong stable trait and by the causes of cognitive change across the life course. Moray House Test scores showed strong concurrent and predictive validity with gold standard cognitive tests at ages 11 and 90.
