  • Title: Sex differences in a landmark environmental re-orientation task only during the learning phase.
    Author: Piccardi L, Bianchini F, Iasevoli L, Giannone G, Guariglia C.
    Journal: Neurosci Lett; 2011 Oct 10; 503(3):181-5. PubMed ID: 21889578.
    Abstract:
    Sex differences are consistently reported in human navigation. Indeed, to orient themselves during navigation women are more likely to use landmark-based strategies and men Euclidean-based strategies. The difference could be due to selective social pressure, which fosters greater spatial ability in men, or biological factors. And the great variability of the results reported in the literature could be due to the experimental setting more than real differences in ability. In this study, navigational behaviour was assessed by means of a place-learning task in which a modified version of the Morris water maze for humans was used to evaluate sex differences. In using landmarks, sex differences emerged only during the learning phase. Although the men were faster than the women in locating the target position, the differences between the sexes disappeared in delayed recall.
