The Female Advantage in Object Location Memory is Robust to Verbalizability and Mode of Presentation of Test Stimuli
Lejbak, Lisa; Vrbancic, Mirna; Crossley, Margaret
Brain and Cognition, v69 n1 p148-153 Feb 2009
This study extends Duff and Hampson's [Duff, S., & Hampson, E. (2001). A sex difference on a novel spatial working memory task in humans. "Brain and Cognition, 47," 470-493] finding of a sex-related difference in favor of females for an object location memory task. Twenty female and 20 male undergraduate students performed both manual and computer-generated versions of the task using stimuli that varied in degree of verbalizability. A 2 x 2 x 3 ANOVA with Sex as a between-subjects factor, and Presentation (manual or computer) and Stimuli (common objects, common shapes, and novel shapes) as within-subjects repeated measures revealed a significant main effect for Sex. Females made fewer errors than males regardless of presentation and across the three levels of verbalizability (i.e., stimulus types); moreover, the effect size was considered "large" [Cohen, J. (1988). "Statistical power analysis for the behavioral sciences" (2nd ed.). Berlin: Springer]. These findings are interpreted within the context of the current literature that demonstrates a female advantage for object location memory (e.g., [Voyer, D., Postma, A., Brake, B., & Imperato-McGinley, J. (2007). Gender differences in object location memory: A meta-analysis. "Psychonomic Bulletin and Review, 14", 23-38]). (Contains 3 tables.)
