An object's location is often remembered relative to one or more landmarks. An object has a certain direction and distance relative to a landmark. When multiple landmarks are available the information from the different landmarks is integrated. In the prevailing view direction and distance are equally influential in the integration process. We present evidence that direction and distance are not always equally influential in landmark-based memory. During the study phase of our task, participants viewed a set of layouts, each comprising a target and two landmarks. During the test phase participants attempted to place each target in the correct location relative to the two landmarks. Our measure of direction deviation indexed the degree to which the targets were placed on the basis of distance rather than solely on the basis of direction. Our measure of distance deviation indexed the degree to which the targets were placed on the basis of direction rather than solely on the basis of distance. Direction deviation was smaller than distance deviation. The results suggest that direction is more influential than distance in memory for the locations of objects relative to landmarks.
物体的位置通常是相对于一个或多个地标来记忆的。物体相对于地标具有特定的方向和距离。当有多个地标可用时，来自不同地标地信息会被整合。在主流观点中，方向和距离在整合过程中具有同等的影响力。我们提供的证据表明，在基于地标地记忆中，方向和距离并不总是具有同等的影响力。在我们任务的研究阶段，参与者观看了一组布局，每个布局都包含一个目标和两个地标。在测试阶段，参与者试图将每个目标放置在相对于两个地标地正确位置。我们的方向偏差度量指标索引了目标是基于距离还是仅基于方向来放置的程度。我们的距离偏差度量指标索引了目标是基于方向还是仅基于距离来放置的程度。方向偏差小于距离偏差。结果表明，在相对于地标记忆物体位置时，方向比距离的影响力更大。
