To examine whether fallow deer, Dama dama, have colour vision, we trained four adult females on a two-choice discrimination task, where a positive chromatic stimulus (green) and a negative achromatic stimulus (grey) had similar brightness.学习的标准设定为 80% 的正确答案。 To exclude the possibility that the hinds used small differences in brightness to distinguish between the green and the grey stimulus, we conducted a test that differed from the training situation. A light green positive stimulus combined with a dark grey negative stimulus was alternated with a dark green positive stimulus combined with a light grey negative stimulus on every second trial.正绿色刺激具有不同的反射光谱。训练结束后，四只后鹿在测试中的正确反应率均超过 80%。 These results suggest that fallow deer can use colour vision in a discrimination situation by generalizing over slightly different colours, at least in the range of the green spectrum.
To examine whether fallow deer, Dama dama, have colour vision, we trained four adult females on a two-choice discrimination task, where a positive chromatic stimulus (green) and a negative achromatic stimulus (grey) had similar brightness. The criterion for learning was set at 80% correct responses. To exclude the possibility that the hinds used small differences in brightness to distinguish between the green and the grey stimulus, we conducted a test that differed from the training situation. A light green positive stimulus combined with a dark grey negative stimulus was alternated with a dark green positive stimulus combined with a light grey negative stimulus on every second trial. The positive green stimuli had different reflectance spectra. After training, each of the four hinds showed over 80% correct responses in the test. These results suggest that fallow deer can use colour vision in a discrimination situation by generalizing over slightly different colours, at least in the range of the green spectrum.
