In the present study, a systematic comparison of sex differences for several tests of spatial memory was conducted. Clear evidence for more accurate male performance was obtained for precise metric positional information in a wayfinding task and in an object location memory task. In contrast, no sex difference characterized topological information processing (object-to-position assignment). Together, these findings provide further insight in the specificity of sex differences in spatial memory and in the functional architecture of spatial memory. Implications for the relevant evolutionary basis are discussed.
在本研究中，对几种空间记忆测试的性别差异进行了系统比较。在寻路任务和物体位置记忆任务中，对于精确的度量位置信息，获得了男性表现更准确的明确证据。相比之下，拓扑信息处理（物体到位置的分配）没有性别差异。这些发现共同为空间记忆中性别差异的特异性以及空间记忆的功能结构提供了进一步的见解。并讨论了相关进化基础的影响。
