Two independent investigations of the association between the temperamental dimensions of inhibition and lack of inhibition to the unfamiliar, on the one hand, and the degree of pigmentation of the iris, on the other, revealed a statistically significant relation in Caucasian children between behavioral inhibition to the unfamiliar and blue irises and uninhibited behavior and brown irises. Several biochemical interpretations of this association were discussed and it was suggested that these behavioral styles might be influenced by biological factors that are partially marked by eye color in Caucasian populations.
两项独立研究，一方面探讨了抑制性气质维度与对陌生事物缺乏抑制性之间的关联，另一方面研究了虹膜色素沉着程度与之的关系。研究发现，在白人儿童中，对陌生事物的行为抑制与蓝色虹膜、无抑制行为与棕色虹膜之间存在统计学上的显著关联。讨论了对这种关联的几种生化解释，并提出这些行为方式可能受到生物学因素的影响，而在白人人群中，这些生物学因素部分地由眼睛颜色体现。
