The Cohort Effect
Captions available
The idea
A cohort effect is a difference between age groups caused by the historical period each group lived through rather than by age.
In practice
Older participants score lower on a computerized task because of unfamiliarity with the interface, not aging.
Where people slip
Every cross-sectional age difference is a candidate cohort effect until something rules it out.
