尽管颜色在我们对视觉世界的主观体验中扮演着重要的角色，但颜色视觉的进化优势仍然不清楚[1-2]，目前大多数答案都指向特殊用途，例如在树叶中检测成熟的水果[3-6]。我们通过观察颜色对模式识别中涉及的编码和检索过程的贡献来研究颜色在视觉识别中是否具有更一般的作用[7-9]。自然场景的彩色图像的识别准确率高于亮度匹配的黑白图像，颜色信息对识别过程的两个组成部分都有贡献。最初，颜色在感官处理的早期阶段会带来图像编码优势，这很可能是通过简化图像分割任务实现的。后来，颜色在检索中带来了优势，这可能是由于附加属性在内存中增强了图像表示的结果。我们的结果将颜色视觉归因于视觉形式处理的一般作用，从分析的最早阶段开始：颜色帮助我们更快地识别事物并更好地记忆它们。(C)2000爱思唯尔科学有限公司。保留所有权利。
Although color plays a prominent part in our subjective experience of the visual world, the evolutionary advantage of color vision is still unclear [1-2], with most current answers pointing towards specialized uses, for example to detect ripe fruit amongst foliage [3-6]. We investigated whether color has a more general role in visual recognition by looking at the contribution of color to the encoding and retrieval processes involved in pattern recognition [7-9]. Recognition accuracy was higher for color images of natural scenes than for luminance-matched black and white images, and color information contributed to both components of the recognition process. Initially, color leads to an image-coding advantage at the very early stages of sensory processing, most probably by easing the image-segmentation task. Later, color leads to an advantage in retrieval, presumably as the result of an enhanced image representation in memory due to the additional attribute. Our results ascribe color vision a general role in the processing of visual form, starting at the very earliest stages of analysis: color helps us to recognize things faster and to remember them better.
