Abstract

New data show that (1) Old Age, and lower scores on the Cattell Culture Fair Intelligence Test predict extent of variability in mean performance from day to day than younger people. (2). Most, but not all, of increased between-session variability is directly caused by increased within-session variability. (3). Increased between-session variability in CRTs can be explained as a consequence of linear scaling of mean CRTs and RT. distributions by Age and gf. Variability in other tasks, in which performance is not directly time-related, requires a different and more general explanation.
