Nissen (1985) presented results showing that in partial-report experiments, selection by location was different from selection by color or by shape. Bundesen (1991) presented a reinterpretation of these results, claiming that they can also be explained by a model in which location selection is treated on a par with selection by color or by shape. We will show that the analysis given by Bundesen is based on a special relation between an "element" in the visual field and its location, which in fact reduces the expressions given by Bundesen to those given by Nissen. Furthermore, we will show that in Bundesen's theory, it is assumed that in the process of perceptual categorization an element in the visual field can be referred to without the use of one of its attributes. This assumption is untenable from a theoretical point of view. In all, the results presented by Nissen can still be regarded as evidence for the difference between selection by location and selection by color or by shape.
尼森（1985年）展示的结果表明，在部分报告实验中，按位置选择不同于按颜色或形状选择。邦德森（1991年）对这些结果进行了重新解释，声称它们也可以用一种模型来解释，在该模型中，位置选择与按颜色或形状选择被同等对待。我们将表明，邦德森给出的分析基于视野中一个“元素”与其位置之间的一种特殊关系，这实际上将邦德森给出的表达式简化为尼森给出的表达式。此外，我们将表明，在邦德森的理论中，假定在感知分类过程中，可以不使用视野中一个元素的某一属性来提及该元素。从理论角度来看，这一假定是站不住脚的。总之，尼森展示的结果仍可被视为位置选择与颜色或形状选择之间存在差异的证据。
