二色性受试者可以准确地说出颜色，即使他们不能区分红绿色色调（Jameson & Hurvich，1978）。这一结果归因于二色性观察者通过学习微妙的视觉线索来弥补他们贫乏的颜色系统而发展的规范语言系统。本研究采用多维标度技术比较色觉缺陷（CVD）受试者和正常三色视（NT）受试者的颜色分类空间，一致性分析估计语言对分类的规范性影响。主题排序140孟塞尔颜色样本在三种不同的方式：一个自由的排序任务（无限数量的类别），一个受约束的排序任务（数量的类别限制为8），和一个受约束的命名任务（限制为8个基本的颜色术语）。CVD颜色类别与NT受试者相当。对于CVD和NT受试者，一个共同的颜色分类空间来自三个任务的三维模型很好地描述，与前两个维度对应的红绿色和黄蓝色的轴。然而，第三轴，这是与一个非彩色尺寸在NT，没有确定在CVD模型。个体差异多维标度未能揭示排序任务的组间差异。相反，CVD受试者的个人颜色命名空间表现出相对压缩的黄蓝色的尺寸，这是不一致的典型的氘型颜色空间来自更直接的措施的感知颜色判断。正如预期的那样，CVD（77%）和NT（82%）之间的最高共识发生在命名任务中。本实验所研究的分类行为似乎更多地依赖于学习因素，而对颜色的CVD知觉表征的揭示可能很少。
Dichromatic subjects can name colors accurately, even though they cannot discriminate among red-green hues (Jameson & Hurvich, 1978). This result is attributed to a normative language system that dichromatic observers developed by learning subtle visual cues to compensate for their impoverished color system. The present study used multidimensional scaling techniques to compare color categorization spaces of color-vision deficient (CVD) subjects to those of normal trichromat (NT) subjects, and consensus analysis estimated the normative effect of language on categorization. Subjects sorted 140 Munsell color samples in three different ways: a free sorting task (unlimited number of categories), a constrained sorting task (number of categories limited to eight), and a constrained naming task (limited to eight basic color terms). CVD color categories were comparable to those of NT subjects. For both CVD and NT subjects, a common color categorization space derived from the three tasks was well described by a three-dimensional model, with the first two dimensions corresponding to reddish-greenish and yellowish-bluish axes. However, the third axis, which was associated with an achromatic dimension in NTs, was not identified in the CVD model. Individual differences multidimensional scaling failed to reveal group differences in the sorting tasks. In contrast, the personal color naming spaces of CVD subjects exhibited a relative compression of the yellowish-bluish dimension that is inconsistent with the typical deutan-type color spaces derived from more direct measures of perceptual color judgments. As expected, the highest consensus among CVDs (77%) and NTs (82%) occurred in the naming task. The categorization behaviors studied in this experiment seemed to rely more on learning factors, and may reveal little about CVD perceptual representation of colors.
