A sample of ppl, slected to repepresent the full pop, is tested every 5 years same ppl tested at diff ages. Advantage: the effects of age on performance of each individual can be studied this allows specific individuals to be singled out and their performance before the onset of disease. For men and women, the lowest iq quartile had the lowest life expectancy. Iq at 11 was correltated with a range of cog and physical fitness measures mainly grip strength, lung function, and time to walk. Physical fitness at 80 was predicted by iq at 11 and was influenced to sex, social class, and the apoe gene (related to epidodic and semantic mem performance in elderly. Different groups od ppl are sampled across the age range and their performance is measured on a single occasion. Problems: one cannot relate performance to earlier data or relate performance to the future development or cohort effects.
