采用避热学习的方法研究了红蜘蛛的颜色辨别能力。实验的竞技场被一对彩纸分成两半。本研究中使用的彩色纸为蓝色、绿色、黄色、红色、白色、灰色和黑色。在训练中，竞技场的一半被一个热板从底部加热，自由行走的蜘蛛被单独训练以避开加热的一半。在随后的无热量记忆测试中，他们始终避免与热量相关的彩色纸。我们发现跳蛛可以学习蓝绿色、蓝黄色、蓝红色、蓝灰色、绿黄色、绿红色、绿灰色、黄红色、黄灰色和红灰色的图案。此外，接受蓝白图案、绿白图案、黄白图案或红白图案训练的蜘蛛可以区分蓝色、绿色、黄色或红色与黑色。跳蛛似乎可以通过颜色来区分蓝色、绿色、黄色和红色的纸张，尽管亮度也可以与颜色线索一起用来区分彩色纸张。
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.
