Color discrimination in jumping spiders Hasarius adansoni was examined by heat-avoidance learning in association with colored papers. The arena for the experiment was divided into two halves by a pair of colored papers. The colored papers used in this study were blue, green, yellow, red, white, gray and black. In training sessions, one half of the arena was heated from the bottom by a hot plate, and freely walking spiders were individually trained to avoid the heated half. In subsequent memory tests without heat, they consistently avoided the heat-associated colored papers. We found that jumping spiders could learn blue-green, blue-yellow, blue-red, blue-gray, green-yellow, green-red, green-gray, yellow-red, yellow-gray and red-gray patterns. Moreover, spiders trained with a blue-white pattern, a green-white pattern, a yellow-white pattern or a red-white pattern could discriminate the blue, green, yellow or red from black. It seems that jumping spiders can discriminate the blue, green, yellow and red papers by their hue, although brightness may also be used together with the color cue to discriminate colored papers.
通过与彩色纸张相关联的热回避学习，对跳蛛哈氏遁蛛的颜色辨别能力进行了研究。实验场地被一对彩色纸张分成两半。本研究中使用的彩色纸张有蓝色、绿色、黄色、红色、白色、灰色和黑色。在训练阶段，场地的一半由热板从底部加热，自由行走的蜘蛛被单独训练以避开受热的一半。在随后无热的记忆测试中，它们始终避开与热相关的彩色纸张。我们发现跳蛛能够学习蓝 - 绿、蓝 - 黄、蓝 - 红、蓝 - 灰、绿 - 黄、绿 - 红、绿 - 灰、黄 - 红、黄 - 灰和红 - 灰模式。此外，用蓝 - 白模式、绿 - 白模式、黄 - 白模式或红 - 白模式训练的蜘蛛能够从黑色中辨别出蓝色、绿色、黄色或红色。似乎跳蛛可以通过色调辨别蓝色、绿色、黄色和红色纸张，尽管亮度也可能与颜色线索一起用于辨别彩色纸张。
