The authors explored the effect of age on executive functions by using 3 tasks (Tower of London, Hayling, and
Brixton tests) designed to assess specific executive processes (planning, inhibition, and abstraction of logical
rules) that were also sensitive to frontal dysfunction.
The performance of elderly participants (n 48) was significantly poorer than that of young participants (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 differences.
These results are discussed in terms
of general and specific factors in cognitive aging.
EVERAL researchers have suggested that cognitive
decline in aging is linked to
