| Abstract | Age differences for nine age groups between 22 and 25 years and 81 and 90 years were evaluated, covarying educational attainment, on five Cattell-Horn-Carroll (CHC) abilities: fluid reasoning (Gf), crystallized ability (Gc), quantitative knowledge (Gq), reading (Grw-Reading), and writing (Grw-Writing). Data were from the adult portions of the stratified standardization samples of the second editions of the Kaufman Brief Intelligence Test (N = 570) and the Kaufman Test of Educational Achievement-Brief Form (N = 555). Gc and Grw-Reading were maintained through old age, whereas Gf, Gq, and Grw-Writing were vulnerable abilities. The age-related decline in mean scores on Gf was powerful, as even the maintained CHC abilities of Gc and Grw-Reading proved to be vulnerable when the component tasks of each were analyzed separately. All Gender x Age interactions were nonsignificant, indicating that age differences for all CHC abilities studied were essentially the same for men and women. (Contains 4 tables and 4 figures.)
