title: Age and sex differences on the hand test.
abstract: Investigated age and sex differences on the Hand Test across the life span, while statistically partialing-out the effects of educational level and verbal ability. Subjects were 150 individuals (75 males, 75 females) ranging in age from 20 to 86 years, assigned to one of three age groups on the basis of their chronological age. Participants were administered the Hand Test and the WAIS vocabulary subtest; in addition, years of formal education completed for each subject was obtained. Results indicated that even after statistically adjusting for the effects of education and verbal ability, a number of significant Age. Sex, Age and Sex, as well as Age x Sex interactions were obtained on the Hand Test. It was suggested that, as previous criticisms of projective research with the aged are met, a residue of important personality trends persists.
