Men are more accurate than women in aiming at targets in both near space and extrapersonal space.

Men excel at motor tasks requiring aiming accuracy whereas women excel at different tasks requiring fine motor skill. However, these tasks are confounded with proximity to the body, as fine motor tasks are performed proximally and aiming tasks are directed at distal targets. As such, it is not known whether the male advantage on tasks requiring aiming accuracy is because men have better aim or is better in the proximal domain in which the task is usually presented. 18 men (M age = 20.6 yr., SD = 3.0) and 20 women (M age = 18.7 yr., SD = 0.9) performed 2 tasks of extrapersonal aiming accuracy (>2 m away), 2 tasks of aiming accuracy performed in near space (< 1 m from them), and a task of fine motor skill. Men outperformed women on both the extrapersonal aiming tasks, and women outperformed men on the task of fine motor skill. However, a male advantage was observed for one of the aiming tasks performed in near space, suggesting that the male advantage for aiming accuracy does not result from proximity.

Throwing accuracy during prism adaptation: male advantage for throwing accuracy is independent of prism adaptation rate.

Previous studies have found that men are more accurate at throwing an object at a target than are women, independent of experience. However, these studies' results are based on average scores from multiple trials. As such, it is unknown whether the male advantage results from superior throwing accuracy or from a superior ability to calibrate subsequent throws. This study examined whether men can calibrate repeated throws more quickly and accurately than women, 25 men and 30 women were required to throw velcro-covered balls at a carpet-covered target, both with and without 10-diopter prism lenses. Participants had multiple trials in both conditions. Analyses examined whether there was a sex difference in the rate of adaptation to the prism lenses (as indicated by calibration of subsequent throws), instead of simply averaging all throwing accuracy scores and looking for an overall sex difference. Men threw the balls significantly more accurately than women, both with and without the prism lenses. However, there was no significant sex difference found on the rate of prism adaptation, as measured by improvement across the trials, i.e., calibration. Although men were more accurate at throwing balls overall, there was no sex difference in calibration of subsequent throws in adapting to the prism lenses, therefore indicating that the male advantage in throwing accuracy does not result from superior ability to calibrate subsequent throws but rather from superior throwing accuracy overall.

Female advantage for spatial location memory in both static and dynamic environments.

A female advantage has previously been found for spatial location tests of object memory. Previous studies have used static, 2-D tasks to test this advantage. This study used a computerized adaptation of the game Concentration to test object location memory in both a static and dynamic array of 24 pairs of line drawings. The dynamic version of this task was used to better reflect the dynamic real world in which we usually use object location memory. Consistent with previous research, we observed a female advantage. This advantage was found to a similar extent in both the static and dynamic versions of the task. The female advantage for object location memory is a concrete advantage in spatial cognition that females show on the Concentration Task, regardless of the nature of the presentation environment.
