来自33项独立研究的数据被结合起来，形成了一个由16个认知变量和6832名年龄在18岁到95岁之间的不同个体组成的综合数据集。研究人员进行了分析，以确定在认知能力的层次结构中，与年龄、性别、教育程度和自我报告的健康状况相关的个体差异可以定位在哪里。结果表明，不同类型的个体差异特征在层次结构中表现出不同的影响模式，其中年龄与四种具有统计学差异的影响相关；消极影响二阶共同因素和一阶速度和记忆因素，积极影响一阶词汇因素。(C) 2004爱思唯尔公司版权所有。
Data from 33 separate studies were combined to create an aggregate data set consisting of 16 cognitive variables and 6832 different individuals who ranged between 18 and 95 years of age. Analyses were conducted to determine where in a hierarchical structure of cognitive abilities individual differences associated with age, gender, education, and self-reported health could be localized. The results indicated that each type of individual difference characteristic exhibited a different pattern of influences within the hierarchical structure, and that aging was associated with four statistically distinct influences; negative influences on a second-order common factor and on first-order speed and memory factors, and a positive influence on a first-order vocabulary factor.
