Summary
Males and females (N = 195) ranging in age from 21 to 86 years were placed into one of three age groups—young (21-40 years), middle-aged (41-60 years), and elderly (61-86 years)—and administered tasks measuring crystallized (WAIS vocabulary subtest) and fluid (Raven's Coloured Progressive Matrices) intellectual abilities. Correlations of WAIS and matrices scores were significant for each of the three age groups, but the obtained correlations were not significantly different when using Fisher's Z score transformation of r.
