Spatial representation surrounding a viewer including outside the visual field is crucial for moving around the three-dimensional world. To obtain such spatial representations, we predict that there is a learning process that integrates visual inputs from different viewpoints covering all the 360° visual angles. We report here the learning effect of the spatial layouts on six displays arranged to surround the viewer, showing shortening of visual search time on surrounding layouts that are repeatedly used (contextual cueing effect). The learning effect is found even in the time to reach the display with the target as well as the time to reach the target within the target display, which indicates that there is an implicit learning effect on spatial configurations of stimulus elements across displays. Since, furthermore, the learning effect is found between layouts and the target presented on displays located even 120° apart, this effect should be based on the representation that covers visual information far outside the visual field.
围绕观察者的空间表示，包括视野之外，对于在三维世界中移动至关重要。为了获得这种空间表示，我们预测存在一个学习过程，该过程整合了来自不同视角的视觉输入，涵盖了所有 360°的视角。我们在这里报告了在六个显示器上的空间布局的学习效果，这些显示器被安排围绕观察者，显示出在重复使用的周围布局上视觉搜索时间缩短（上下文提示效应）。即使在到达带有目标的显示器的时间以及在目标显示器内到达目标的时间上也发现了学习效果，这表明在跨越显示器的刺激元素的空间配置上存在隐式学习效果。由于，此外，在相隔 120°的显示器上呈现的布局和目标之间也发现了学习效果，因此该效果应该基于覆盖远视野外视觉信息的表示。
