In a completely between subjects design 80 male and 80 female undergraduates evaluated targets which were male or female and 25, 45, 65, or 85 years old, on the Aging Semantic Differential (ASD; Rosencranz & McNevin, 1969). Findings indicated that older targets were rated less positively than younger targets on two of the three ASD dimensions and that Target Age × Target Sex × Subject Age interactions were significant for two of the dimensions. These results replicate the target age (between subjects) effects reported by O'Connell and Rotter (1979) but not those which involved target sex (within subjects) and subject sex. It was concluded that a) subject sex and target sex affect perceptions of targets of different ages elicited from young subjects and b) between subjects versus within subjects designs produce different characterizations of such targets.
