The notion that phenomenologically observable differences in the human eye are correlated with behavioral tendencies (other than gaze-following) has been addressed poorly in the psychological literature. Most notably, the proposed correlations are based on an arbitrary categorization in discrete categories of the continuous variability across various traits that could be contributing to individual eye morphologies. We review the relevant literature and assume a view of human eyes as sign stimuli, identifying the relative contrast between the iridal and scleral areas as the main contributor to the strength of the signal. Based on this view, we present a new method for the precise quantification of the relative luminosity of the iris (RLI) and briefly discuss its potential applications in psychological research.
人类眼睛在现象学上可观察到的差异与行为倾向（除了视线跟随）相关这一观点，在心理学文献中很少被提及。最值得注意的是，所提出的相关性基于对各种可能导致个体眼睛形态的特征连续变化进行的任意离散分类。我们回顾了相关文献，并假设将人类眼睛视为信号刺激，将虹膜和巩膜区域之间的相对对比度确定为信号强度的主要贡献因素。基于这一观点，我们提出了一种精确量化虹膜相对亮度（RLI）的新方法，并简要讨论了其在心理学研究中的潜在应用。
