We conducted a visibility graph analysis (a Space Syntax method) of a virtual environment to examine how the configurational salience of global and local landmarks (i.e., their relative positions in the environment) as compared to their visual salience affects the probability of their depiction on sketch maps. Participants of two experimental conditions produced sketch maps from memory after exploration with a layout map or without a map, respectively. Participants of a third condition produced sketch maps in parallel to exploration. More detailed sketch maps were produced in the third condition, but landmarks with higher configurational salience were depicted more frequently across all experimental conditions. Whereas the inclusion of global landmarks onto sketch maps was best predicted by their size, both visual salience and isovist size (i.e., the area a landmark was visible from) predicted the frequency of depiction for local landmarks. Our findings imply that people determine the relevance of landmarks not only by their visual, but even more by their configurational salience.
我们对一个虚拟环境进行了可见性图分析（一种空间句法方法），以研究全局和局部地标的配置显著性（即它们在环境中的相对位置）与其视觉显著性相比，如何影响它们在草图上被描绘的概率。两个实验条件下的参与者分别在使用布局图探索或不使用地图探索后凭记忆绘制草图。第三个条件下的参与者在探索的同时绘制草图。在第三个条件下绘制的草图更详细，但在所有实验条件下，配置显著性较高的地标被描绘得更频繁。虽然草图上全局地标的纳入情况最好由其大小预测，但视觉显著性和视域大小（即从一个地标可见的区域）都能预测局部地标被描绘的频率。我们的研究结果表明，人们不仅根据地标的视觉特征，更根据其配置显著性来确定地标的相关性。
