绿色、蓝色、黄色和白色作为独特的色调与其他色调区分开来。我们提出了两个实验的结果，破坏了现有的行为证据，以区分独特的色调从其他颜色。在实验1中，我们使用了色调缩放，这经常被用来支持存在的独特色调，但从来没有尝试过一组非独特的原色。受试者被分配到两个实验条件之一。在“独特”的条件下，他们对一系列测试刺激中的每一种所感知到的红色、黄色、蓝色和绿色的比例进行评级。在“中间”条件下，他们对蓝绿色、紫色、橙子和酸橙的比例进行了评级。令人惊讶的是，我们发现这两种情况下的结果在很大程度上是相同的。在实验二中，我们考察了教学对被试独特色调设置的影响。我们发现，改变说明书中给出的颜色术语，包括中间色调，会导致受试者认为独特的色调发生显著变化。两个实验的结果都质疑了受试者识别特定色调的能力。(C)2014年美国光学学会
green, blue, yellow, and white have been distinguished from other hues as unique. We present results from two experiments that undermine existing behavioral evidence to separate the unique hues from other colors. In Experiment 1 we used hue scaling, which has often been used to support the existence of unique hues, but has never been attempted with a set of non-unique primaries. Subjects were assigned to one of two experimental conditions. In the "unique" condition, they rated the proportions of red, yellow, blue, and green that they perceived in each of a series of test stimuli. In the "intermediate" condition, they rated the proportions of teal, purple, orange, and lime. We found, surprisingly, that results from the two conditions were largely equivalent. In Experiment 2, we investigated the effect of instruction on subjects' settings of unique hues. We found that altering the color terms given in the instructions to include intermediate hues led to significant shifts in the hue that subjects identified as unique. The results of both experiments question subjects' abilities to identify certain hues as unique. (C) 2014 Optical Society of America
