Abstract
The authors explored the effect of age on executive functions by using 3 ta sks (Tower of London, Hayling, and Brixton tests) designed to assess specif ic executive processes (planning, inhibition, and abstraction of logical ru les) that were also sensitive to frontal dysfunction. The performance of el derly participants (n = 48) was significantly poorer than that of young par ticipants (n = 47) in all 3 tasks. Processing speed, measured by means of a color-naming task, explained some but not all of the age-related differenc es. These results are discussed in terms of general and specific factors in cognitive aging.
