目前认知老化领域的大部分研究都集中在调查被认为是造成特定认知任务中观察到的年龄差异的特定过程。本文的一个中心论点是,与年龄有关的认知变量的影响很少孤立地发生,因此,他们最好的解释的背景下,变量之间存在的结构相互关系和年龄的关系,组织结构。2个独立的数据集的分析结果表明,在广泛的认知变量的年龄相关的影响大部分是共享的,独立的,或独特的,年龄相关的影响往往有助于相对较小的年龄差异观察到许多认知变量。这些研究结果意味着,重要的是要考虑的结构内发生的变量时,试图调查的过程负责与年龄有关的变量上的差异。
Much of the current research in the area of cognitive aging has been focused on investigating specific processes presumed to be responsible for the age differences observed in particular cognitive tasks. A central thesis of this article is that age-related effects on cognitive variables seldom occur in isolation, and hence, they are best interpreted in the context of the structural interrelations that exist among variables and the relations of age on that organizational structure. Results from analyses of 2 separate data sets suggest that large proportions of the age-related effects across a wide range of cognitive variables are shared and that independent, or unique, age-related effects often contribute relatively little to the age differences observed in many cognitive variables. These findings imply that it is important to consider the structure within which a variable occurs when attempting to investigate the processes responsible for age-related differences on that variable.
