Incremental effects of categorical education on cognitive trajectory components in the overall sample (N=1499). Results are from models in which education was entered individually along with covariates age, gender, and language of test administration (covariate effects not shown). Reference values refer to females 70 years of age tested in English with more than 12 years of education. 3MS and VM have a mean of 100 and SD of 15.
