title: Predicting normal age-related changes with intelligence, projective, and perceptual-motor test variables.
abstract: From four tests, the WAIS, Rorschach, Hand Test, and Bender-Gestalt, 67 variables were derived and used to predict age for 240 individuals. Ages ranged from 15 to 65 yr., divided into five age intervals, with 48 subjects per group. 36 variables correlating with age were further reduced to 12 by means of a stepwise multiple R. A final R of .73 was obtained, accounting for 53% of the variance. While variables from all four of these tests correlated with the criterion, most of the significant variance could be attributed to intellectual factors.
