| Annotation | A prominent hypothesis in cognitive ageing is the existence of a common factor that is responsible for age-related deterioration in cognitive and non-cognitive processes. A multiple indicators, multiple causes model was used to examine the nature of this common factor and its relationship to age, gender and the apolipoprotein E (apoE) genotype. The common factor was modelled by using 10 indicator variables with 374 participants aged between 77.4 and 98.7 years. A latent factor was identified, with all indicators except blood pressure loading significantly. This factor could be identified in two age strata within the sample. After controlling for the effects of gender, apoE was significantly associated with memory but not with the common factor. The findings suggest that a number of specific processes may operate concurrently with any common cause factor. (RH). |
