Exogenous covert attention is an automatic, transient form of attention that can be triggered by sudden changes in the periphery. Here we test for the effects of attention on color perception. We used the methodology developed by Carrasco, Ling, and Read [Carrasco, M., Ling, S., & Read, S. (2004). Attention alters appearance. Nature Neuroscience, 7 (3) 308-313] to explore the effects of exogenous attention on appearance of saturation (Experiment 1) and of hue (Experiment 2). We also tested orientation discrimination performance for single stimuli defined by saturation or hue (Experiment 3). The results indicate that attention increases apparent saturation, but does not change apparent hue, notwithstanding the fact that it improves orientation discrimination for both saturation and hue stimuli.
外源性隐蔽注意是一种自动的、短暂的注意形式，可由外周的突然变化触发。在此，我们测试注意对颜色感知的影响。我们采用了卡拉斯科、凌和里德[卡拉斯科，M.，凌，S.，&里德，S.（2004年）。注意改变外观。《自然神经科学》，7（3）308 - 313]开发的方法，以探究外源性注意对饱和度外观（实验1）和色调外观（实验2）的影响。我们还测试了由饱和度或色调定义的单个刺激的方向辨别性能（实验3）。结果表明，尽管注意提高了对饱和度和色调刺激的方向辨别能力，但它增加了表观饱和度，却不改变表观色调。
