How males and females differ in their use of cues for spatial navigation is an important question. Although women and men appear to respond differently to close and distant objects, object features and the geometry of spaces, the common denominator of these sex-specific cue preferences is unknown. By constructing virtual landscapes from either directional (graded, gradient) or positional (pinpoint) cues, the authors tested the hypothesis that sex differences arise from preferences for cues that provide primarily direction or position, as predicted by the parallel map model of the cognitive map. Women and men learned a target location in the presence of either one or the other class of cues. Men were more accurate in estimating the target location overall, but the navigation accuracy difference between men and women was greater in the presence of directional cues. Our findings provide support for the parallel map model and suggest that the previously reported male advantage in the presence of distant objects and geometric cues derives from their function as directional cues.
男性和女性在使用空间导航线索方面有何不同是一个重要问题。尽管男性和女性对近处和远处物体、物体特征以及空间几何形状的反应似乎有所不同,但这些特定性别的线索偏好的共同特征尚不清楚。通过利用方向(渐变、梯度)或位置(精确点)线索构建虚拟景观,作者检验了这样一个假设:正如认知地图的平行地图模型所预测的那样,性别差异源于对主要提供方向或位置的线索的偏好。男性和女性在存在这两类线索中的一类的情况下学习目标位置。总体而言,男性在估计目标位置方面更准确,但在存在方向线索的情况下,男性和女性之间的导航准确性差异更大。我们的研究结果为平行地图模型提供了支持,并表明先前报道的男性在存在远处物体和几何线索时的优势源于它们作为方向线索的功能。
