| Annotation | 687 individuals aged 25-103 years (those aged 70-103 from the Berlin Aging Study) 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. 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. The authors argue that the increase in the age-associated link between sensory and intellectual functioning may reflect brain ageing. The search for explanations of cognitive ageing phenomena would benefit from attending to factors shared between the two domains. |
