对 3400 多名年龄从 5 岁到 93 岁的个体的数据进行了分析，以调查认知变量的结构组织，并利用该结构来检查认知能力和神经心理学变量之间的关系。结果表明，在儿童和成人中，这些变量可以被组织成相同的认知能力因素，并且在生命的两个阶段，对认知功能测量的年龄相关影响的很大一部分是在不同的认知能力之间共享的。另一组分析表明，许多神经心理学变量与既定的认知能力密切相关，尽管不同年龄组的影响模式有所不同。最后，人们发现，假设反映执行功能的变量缺乏结构有效性，因为这些变量的共同点和流体智力的结构之间存在着几乎完美的个体差异重叠。 (c) 2006 年，爱思唯尔公司出版。
Data from over 3400 individuals ranging from 5 to 93 years of age were analyzed to investigate the structural organization of cognitive variables, and to use that structure to examine relations between cognitive abilities and neuropsychological variables. The results indicated that the variables could be organized into the same cognitive ability factors in both children and adults, and that in both segments of the lifespart a large proportion of the age-related influences on measures of cognitive functioning was shared across different cognitive abilities. Another set of analyses revealed that many neuropsychological variables were closely related to established cognitive abilities, although the pattern of influences varied somewhat across different age groups. Finally, variables assumed to reflect executive functioning were found to lack construct validity because there was nearly perfect overlap of the individual differences in what these variables had in common and a construct of fluid intelligence.
