Adult age (24 years to 91 years) was examined as a potential moderator of the relations among cognitive abilities in an aggregate dataset based on studies conducted at the Cognitive Aging Lab at the University of Virginia (N = 2,227). A novel approach was applied by which the manifestations of latent ability factors were free to differ across age groups, and age trends in the interrelations among the factors were tested. Contrary to the dedifferentiation hypothesis, there was no evidence for systematic increases in the magnitudes of relations among cognitive abilities. Conventional analytic procedures replicated these findings.
基于弗吉尼亚大学认知老化实验室开展的研究(N = 2227),在一个综合数据集中考察了成年年龄(24岁至91岁)作为认知能力之间关系的潜在调节因素。采用了一种新颖的方法,即潜在能力因素的表现形式在不同年龄组之间可以自由变化,并对这些因素之间相互关系的年龄趋势进行了检验。与去分化假说相反,没有证据表明认知能力之间关系的强度有系统性增加。传统分析程序也重复了这些发现。
