蓝色超文本是一个完美的设计决策：在阅读和成功突出相关信息时没有感知上的缺点
Blue hypertext is a perfect design decision: No perceptual disadvantage in reading and successful highlighting of relevant information
摘要：
互联网中突出显示的文本（即超文本）主要是蓝色和下划线。这些超文本特征的概念受到了应用研究和实证测试的严重质疑，导致了不确定的结果。在中央凹和旁视觉中识别蓝色文本的能力被确定为可能受到以中央凹为中心的蓝光敏感视网膜细胞数量少的限制。本研究探讨了在阅读过程中，超文本的中央凹和旁视知觉是否会降低。同时眼动记录和无形的边界范式，它允许调查的中心凹和旁视知觉，分别实现了一个无声的句子阅读研究。句子中的目标词以黑色或蓝色表示，下划线或正常。颜色和下划线没有影响，但可以检测到第一遍阅读测量的预览益处（比较降级与未降级的旁视预览后的注视时间）。固定时间测量包括重读（即，总观看时间）显示，除了预览效果之外，与突出显示的目标词（蓝色或下划线或两者）相比，未突出显示的（黑色无下划线）的注视时间减少。因此，目前的模式反映了超链接刺激没有可检测的感知缺点，但增加了注意力资源的吸引力，第一次通过阅读后，通过突出显示。蓝色或下划线的文本可以让读者很容易地感知超文本，同时由于突出显示，读者重新访问超文本的时间更长。根据目前的证据，蓝色超文本可以安全地推荐给网页设计师供未来使用。
英文摘要：
Highlighted text in the Internet (i.e. Hypertext) is predominantly blue and underlined. The percept of these hypertext characteristics were heavily questioned by applied research and empirical tests resulted in inconclusive results. The ability to identify blue text in foveal and parafoveal vision was identified as potentially constrained by the low number of foveally centered blue light sensitive retinal cells. The present study investigates if foveal and parafoveal perceptibility of hypertext is reduced during reading. A silent-sentence reading study with simultaneous eye movement recordings and the invisible boundary paradigm, which allows the investigation of foveal and parafoveal perceptibility, separately, was realized. Target words in sentences were presented in either black or blue and either underlined or normal. No effect of color and underlining, but a preview benefit could be detected for first pass reading measures (comparing fixation times after degraded vs. un- degraded parafoveal previews). Fixation time measures that included re-reading (i.e., total viewing times) showed, in addition to a preview effect, a reduced fixation time for not highlighted (black not underlined) in contrast to highlighted target words (either blue or underlined or both). Thus, the present pattern reflects no detectable perceptual disadvantage of hyperlink stimuli but increased attraction of attention resources, after first pass reading, through highlighting. Blue or underlined text allows readers to easily perceive hypertext and at the same time readers re-visited hypertext longer as a consequence of highlighting. On the basis of the present evidence blue hypertext can be safely recommended to web designers for future use.
