观察者被要求搜索和找到一个目标刺激，不同的干扰刺激只有色度。选择成对的目标色和干扰色，使得在某些条件下，成对的两个成员在色调、饱和度或色调和饱和度上都不同。对于每种类型的条件，选择了一些代表不同程度的感知差异的颜色对，每对颜色中的每个成员都充当目标颜色和干扰颜色，而另一个成员则充当其余的角色。当目标和干扰物的饱和度不同时，搜索时间的不对称性最大，饱和度和色调的差异时，搜索时间的不对称性较小，色调差异时，搜索时间的不对称性较小。结果表明，不对称性与编码和传输彩色信息所需的时间有关，而不是搜索过程本身的属性。版权所有（C）1996 Elsevier Science Ltd.
Observers were required to search for and find a target stimulus that differed from distracter stimuli only in chromaticity. Pairs of target and distracter colors were chosen so that in some conditions the two members of a pair differed in hue, in saturation, or in both hue and saturation. For each type of condition, a number of pairs of colors representing varying degrees of perceptual difference were chosen, Each member of each pair of colors served as both the target and distracter color while the other member of the pair served in the remaining role. The largest asymmetries in search times occurred when the target and distracters differed in saturation, Somewhat smaller asymmetries occurred with differences in both saturation and hue, and no asymmetries occurred with hue differences. Results suggest that the asymmetries are related to the time required to encode and transmit the chromatic information centrally rather than the properties of the search process itself.
