UNLABELLED
A theory is presented that attempts to answer two questions. What visual contents can an observer consciously access at one moment?
ANSWER
only one feature value (e.g., green) per dimension, but those feature values can be associated (as a group) with multiple spatially precise locations (comprising a single labeled Boolean map). How can an observer voluntarily select what to access?
ANSWER
in one of two ways: (a) by selecting one feature value in one dimension (e.g., selecting the color red) or (b) by iteratively combining the output of (a) with a preexisting Boolean map via the Boolean operations of intersection and union. Boolean map theory offers a unified interpretation of a wide variety of visual attention phenomena usually treated in separate literatures. In so doing, it also illuminates the neglected phenomena of attention to structure.
未加标注
提出了一种理论，试图回答两个问题。观察者在某一时刻能有意识地获取哪些视觉内容？
答案
每个维度仅一个特征值（例如，绿色），但这些特征值可以（作为一组）与多个空间精确位置相关联（构成一个单一的标记布尔地图）。观察者如何自愿选择要获取的内容？
答案
通过以下两种方式之一：（a）在一个维度中选择一个特征值（例如，选择红色），或（b）通过交集和并集的布尔运算，将（a）的输出与预先存在的布尔地图进行迭代组合。布尔地图理论为通常在不同文献中处理的各种视觉注意现象提供了统一的解释。这样做时，它还阐明了被忽视的对结构的注意现象。
