This design combines both cross-sectional and longitudinal designs, as it involves testing different age groups at the same time and then following them up over a period of time. In this case, Professor Rashad is comparing 6-year-olds and 10-year-olds, and then testing them again five years later. This allows for the investigation of both age effects and cohort effects.
