对687名年龄在25 - 103岁的个体进行了横断面研究，以检验感觉功能（视觉和听觉敏锐度）的测量指标与智力（代表心理测量智力的五因素空间的14项认知任务）之间的关系。正如所预测的那样，与感觉功能相关的智力功能个体差异的平均比例从成年期（25 - 69岁）的11%增加到老年期（70 - 103岁）的31%。然而，流体智力能力与感觉功能之间的联系，尽管程度不同，但在两个年龄组中都与年龄呈现出相似的高度相关性。讨论了几种解释，包括“共同原因”假说。在这方面，我们认为感觉和智力功能之间与年龄相关的联系的增加可能反映了大脑衰老，并且对认知衰老现象的解释的探索将受益于关注这两个领域共有的因素。
Six hundred eighty seven individuals ages 25-103 years were studied cross-sectionally to examine the relationship between measures of sensory functioning (visual and auditory acuity) and intelligence (14 cognitive tasks representing a 5-factor space of psychometric intelligence). As predicted, the average proportion of individual differences in intellectual functioning connected to sensory functioning increased from 11% in adulthood (25-69 years) to 31% in old age (70-103 years). However, the link between fluid intellectual abilities and sensory functioning, albeit of different size, displayed a similarly high connection to age in both age groups. Several explanations are discussed, including a ''common cause'' hypothesis. In this vein, we argue that the increase in the age-associated link between sensory and intellectual functioning may reflect brain aging and that the search for explanations of cognitive aging phenomena would benefit from attending to factors that are shared between the 2 domains.
