Abstract

A forced-choice discrimination procedure was used to test color vision and visual sensitivity in 10 squirrel monkeys (Saimiri sciureus) originating from three geographical locations (Bolivia, Colombia, Guyana). In agreement with results from an earlier study of vision in squirrel monkeys of Peruvian origin, striking individual variations in color vision were found among these squirrel monkeys. Some of these animals had trichromatic color vision, while others were dichromats. Within these two categories, a total of five color vision phenotypes could be discerned. Most of these types are qualitatively similar to common forms of human color-defective vision.

摘要

采用强制选择辨别程序，对来自三个地理区域（玻利维亚、哥伦比亚、圭亚那）的10只松鼠猴（松鼠猴属）进行了色觉和视觉敏感度测试。与早期对秘鲁原产松鼠猴视觉的研究结果一致，在这些松鼠猴中发现了显著的个体色觉差异。其中一些动物具有三色视觉，而另一些则是二色视者。在这两类中，总共可辨别出五种色觉表型。这些类型中的大多数在质量上与人类常见的色觉缺陷形式相似。
