The relationship between visual attentional selection of items in particular spatial locations and selection by nonspatial criteria was investigated in a partial report experiment with report of letters (as many as possible) from brief postmasked exposures of circular arrays of letters and digits. The data were fitted by mathematical models based on Bundesen's (Psychological Review, 97, 523-547, 1990) theory of visual attention (TVA). Both attentional weights of targets (letters) and attentional weights of distractors (digits) showed strong variations across the eight possible target locations, but for each of the ten participants, the ratio of the weight of a distractor at a given location to the weight of a target at the same location was approximately constant. The results were accommodated by revising the weight equation of TVA such that the attentional weight of an object equals a product of a spatial weight component (weight due to being at a particular location) and a nonspatial weight component (weight due to having particular features other than locations), the two components scaling the effects of each other multiplicatively.
在一项部分报告实验中，通过短暂的掩蔽后呈现字母和数字的圆形数组，研究了特定空间位置的项目的视觉注意力选择与非空间标准选择之间的关系。数据通过基于 Bundesen（1990 年，《心理学评论》，97，523-547）视觉注意理论（TVA）的数学模型进行拟合。目标（字母）的注意力权重和分心物（数字）的注意力权重在八个可能的目标位置都表现出强烈的变化，但对于每个十位参与者，给定位置上的分心物的权重与同一位置上的目标的权重的比值基本保持不变。通过修改 TVA 的权重方程，使物体的注意力权重等于空间权重分量（由于位于特定位置而产生的权重）和非空间权重分量（由于具有特定特征而产生的权重，除了位置）的乘积，这两个分量以乘法方式相互缩放影响，从而适应了结果。
