作者报告了柏林老龄化研究中132名个体(平均年龄T-1=78.27，年龄范围=70-100)6年纵向变化的4种智力的全信息纵向年龄梯度。相对于横断面母体样本(N=516，平均年龄T-1=84.92岁)，由于不同的死亡率和实验磨损，该样本被正面选择。知觉速度、记忆力和流畅度随着年龄的增长而下降。相比之下，知识在90岁之前一直保持稳定，之后有下降的迹象。老年(n=66，T-1=83.04)的年龄梯度比老年(n=66，T-1=73.77)的年龄梯度更负。男性和女性之间或生活史地位高和低的参与者之间的下降速度没有可靠的差异。他们得出结论，70岁以后的智力发展因距离死亡的距离、年龄和智力能力领域而不同。
The authors report full-information longitudinal age gradients in 4 intellectual abilities on the basis of 6-year longitudinal changes in 132 individuals (mean age at T-1 = 78.27, age range = 70-100) from the Berlin Aging Study. Relative to the cross-sectional parent sample (N = 516, mean age at T-1 = 84.92 years), this sample was positively selected because of differential mortality and experimental attrition. Perceptual speed, memory, and fluency declined with age. In contrast, knowledge remained stable up to age 90, with evidence for decline thereafter. Age gradients were more negative in old old (n = 66, mean age at T-1 = 83.04) than in old (n = 66, mean age at T-1 = 73.77) participants. Rates of decline did not differ reliably between men and women or between participants with high versus low life-history status. They conclude that intellectual development after age 70 varies by distance to death, age, and intellectual ability domain.
