Abstract

Measures of processing speed, memory, and reasoning were administered to 8- to 12-year-olds and adults to examine the causal relation among processing speed, memory, and reasoning. Age was correlated positively with measures of processing speed, memory, and reasoning. Path analyses indicated that age-related changes in processing speed is associated with an increase in memory and an increase in reasoning, but changes in memory mediated through changes in processing speed is not associated with an increase in reasoning.
