视觉地标引入系统的扭曲到空间短期记忆的单个目标位置，扭曲的确切形式取决于地标的空间布局。在两个实验中，我们研究了如何从单个地标的效果预测两个地标的组合效果。参与者使用鼠标光标来再现在一个、另一个或两个地标的背景下简要呈现的目标的位置。我们发现，一个地标附近的失真是独立的另一个地标是否存在，使记忆空间被分割成由单个地标为主的区域。有趣的是，显示器中点的行为就像一个“虚拟地标”，具有自己的扭曲模式。结果与目前的空间记忆失真模型不一致，但表明注意过程可以导致增强的保真度的地形神经网络中的显着区域，同时也引入了一些空间偏差。
Visual landmarks introduce systematic distortions into spatial short-term memory for single target positions, the exact form of the distortion depending on the spatial layout of the landmarks. In two experiments, we investigated how the combined effect of two landmarks can be predicted from the effects of individual landmarks. Participants used a mouse cursor to reproduce the positions of briefly presented targets in the context of one, the other, or both landmarks. We found that distortions near a landmark are independent of whether another landmark is present, so that remembered space is partitioned into regions dominated by single landmarks. Interestingly, the display midpoint behaves like a “virtual landmark,” with its own pattern of distortion. Results are inconsistent with current models of spatial memory distortions but suggest that attentional processes can lead to enhanced fidelity of salient regions in topographical neural networks while also introducing some spatial biases.
