颜色能提高物体识别能力吗？如果是这样的话，对于空间分辨率低、形状信息少的图像，改善是否更大？低视力的人从颜色中受益更多吗？三个实验测量反应时间（RT）和准确性命名的食物对象显示在4种类型的图像：灰度或颜色，和高或低的空间分辨率（由模糊产生）。视力正常的Ss具有更快的彩色RT，但对于低空间分辨率的图像，改善并不显著。低视力受试者也更快的颜色，但差异并不显着取决于敏锐度。在另外两个实验中，发现颜色刺激的快速反应时间与物体的原型性有关，但与颜色诊断性无关。结论是，颜色确实提高了物体识别，其机制可能是感官而不是认知的起源。
Does color improve object recognition? If so, is the improvement greater for images with low spatial resolution in which there is less shape information? Do people with low visual acuity benefit more from color? Three experiments measured reaction time (RT) and accuracy for naming food objects displayed in 4 types of images: gray scale or color, and high or low spatial resolution (produced by blur). Normally sighted Ss had faster RTs with color, but the improvement was not significantly greater for images with low spatial resolution. Low vision subjects were also faster with color, but the difference did not depend significantly on acuity. In 2 additional experiments, it was found that the faster RTs for color stimuli were related to objects' prototypicality but not to their color diagnosticity. It was concluded that color does improve object recognition, and the mechanism is probably sensory rather than cognitive in origin.
