Age differences in tests of intelligence and memory in high and low ability subjects

Abstract

High intelligence has been claimed to 'compensate' age-related changes in intelligence and memory. In the present study, elderly eminent academics and young PhD students were compared to elderly and young manual workers. The subjects were required to complete both experimental and standard tests of intelligence and memory. Age differences were reduced in high ability subjects on tests of geometric and verbal analogies but not on tests of 'ecologically valid' problem solving and memory. Significant reductions in memory and cognitive performance in an elite elderly sample were confirmed. Show more
