The temporal resolution of colour vision was measured in freely-flying honeybees by testing the performance of trained bees in discriminating between two stimuli, one of which presented a steady, homogeneous mixture of two colours, while the other offered a heterochromatic flicker between the two colours at various temporal frequencies. Pairwise combinations of the colours uv, blue and green were used, corresponding to the three receptor classes in the bee retina. For each colour combination, we determined a cutoff frequency beyond which discrimination no longer exists. For a given colour combination, the cutoff frequency depends upon the ratio of the intensities of the component colours, and is maximum at a particular ratio. The cutoff frequency at the optimum intensity ratio is approximately 100 Hz for each of the 3 colour combinations blue-green, green-uv and uv-blue, implying that colour computation requires ca. 10 ms. From the optimum intensity-ratios for the three colour combinations, we infer that the relative sensitivities of the green, blue and uv channels are approximately 1:1.3:24.
通过测试经过训练的蜜蜂区分两种刺激的能力，来测量自由飞行的蜜蜂的色觉时间分辨率。其中一种刺激呈现两种颜色的稳定、均匀混合，而另一种则在不同时间频率下在两种颜色之间提供异源闪烁。使用了紫外线、蓝色和绿色这三种颜色的两两组合，对应于蜜蜂视网膜中的三类受体。对于每种颜色组合，我们确定了一个截止频率，超过该频率辨别能力就不再存在。对于给定的颜色组合，截止频率取决于组成颜色的强度比，并且在特定比例下最大。对于蓝绿、绿紫外和紫外蓝这三种颜色组合中的每一种，在最佳强度比下的截止频率约为100Hz，这意味着颜色计算大约需要10毫秒。从这三种颜色组合的最佳强度比中，我们推断出绿色、蓝色和紫外通道的相对灵敏度约为1:1.3:24。
