“…Although care is required in generalising from the very small sample in this study (even though well-matched in age and IQ), the findings are consistent with gender differences found in larger studies. In contrast to mental rotation and spatial navigation which typically reveal an advantage for males over females (Astur, Ortiz, & Sutherland, 1998;Dabbs, Chang, Strong, & Milun, 1998;Moffatt, Hampson, & Hatzipantelis, 1998), females outperform males when asked to identify which object of a set of objects has been moved (McBurney, Gaulin, Devineni, & Adams, 1997;Silverman & Eals, 1992)-the basic paradigm used here. The exceptions to this female advantage in conditions subject and subject&cue-card perhaps indicates an advantage for men in using internal updating that is masked by the advantage for women when visual snapshots can be used.…”
