| Annotation | Cross-sectional and longitudinal age effects on cognitive function were examined in 302 older adults followed longitudinally. Processing speed was related to cognitive performance at cross-section, and change in speed predicted within-person longitudinal cognitive decline. Statistical control of processing speed greatly reduced cross-sectional age effects, but did not attenuate longitudinal ageing effects. This difference in the ability of processing speed to account for cross-sectional and longitudinal age effects is discussed in the context of theories of cognitive ageing and methodological and statistical issues pertaining to the cross-sectional and longitudinal study of cognitive ageing.
