在低效的视觉搜索任务中，当某些干扰项(旧项)优先于其他项(新项)出现时，搜索变得更容易，就好像观察者能够将旧项排除在搜索之外一样。当通过视觉标记过程使旧物品的位置相对于新物品的位置被剥夺时，就会发生这种现象，称为预览利益。已经证明，如果旧项目之间的空间关系保持不变，则当旧项目在显示器上移动时，预览益处持续存在，这表明用于视觉标记的记忆模板代表了旧项目的空间配置。剩下的一个问题是，这个构型是用二维还是三维坐标编码的。在这项研究中，我们考察了当所有项目都以三维坐标图形呈现并以恒定角速度绕垂直轴刚性旋转时，是否保留了预览收益。在这种情况下出现了预览收益，这表明视觉标记的记忆模板代表了三维坐标中的空间构形。
When some distractors (old items) are presented prior to others (new items) during an inefficient visual search task, search becomes easier, as though observers were able to exclude the old items from the search. This phenomenon, called preview benefit, occurs when the locations of the old items are deprioritized relative to the locations of the new items, through a process of visual marking. It has been demonstrated that preview benefit persists when the old items move on the display, if the spatial relationships among the old items remain unchanged, suggesting that the memory template for visual marking represents the spatial configuration of the old items. One remaining question is whether the configuration is coded in two- or three-dimensional coordinates. In the present study, we examined whether preview benefit was preserved when all items were graphically rendered in three-dimensional coordinates and rigidly rotated around the vertical axis at a constant angular velocity. Preview benefit occurred in this situation, suggesting that the memory template for visual marking represents the spatial configuration in three-dimensional coordinates.
