摘要

A sample of 4,314 volunteers who, when first recruited, were aged from 41 to 93 years were quadren-nially tested from 2 to 4 occasions during the next 4 to 20 years on the Cattell Culture Fair intelligencetest, 2 tests of information-processing speed, the Wechsler Adult Intelligence Scale (WAIS) vocabu-lary test, and 3 memory tests. After significant effects of practice, sex, demographics, socio-economicadvantage, and recruitment cohort had been identified and considered, performance on all testsdeclined with age. These age-related declines accelerated for the Cattell and WAIS, 2 tests ofinformation speed, and 2 of the memory tests. For all tests individuals' trajectories of age-relatedchange diverged with increasing age but, unexpectedly, were not affected by demographic factors.Practice gains from an initial experience of the cognitive tests remained undiminished as the intervalbefore the second experience increased from 4 to 8 + years.
