宾汉姆顿大学的科普网站指出,狗的视觉只有蓝黄双色,因此它们的眼中是两种基色的世界;至于我们的视觉则可以辨别三原色,因而我们看到一个丰富多彩的世界。
DogTV, an HDTV cable channel designed for dogs, interests canines because HDTV has a much higher number of frames per second and is specially colored to accommodate dogs' dichromatic vision, said Dodman, who is the channel's chief scientist.
作为DogTV DogTV has modes for relaxation, which shows images like dogs chilling out in a grassy field; stimulation, which depicts scenes like dogs surfing in southern California; and exposure which shows things like a dog reacting to a ringing doorbell and obeying commands to acclimate them to such situations at home.
狗狗频道提供了多种多样的放松休闲:有汪星人在草地上自由自在的休闲节目、有汪星人在南加州冲浪的刺激性节目,还有播放狗狗听到门铃做出反应、听从指挥等帮助汪星人适应家庭生活的探索教育节目。
Doggie Style 汪星人风格
Beyond biology, how dogs react to TV—whether it's running around, barking excitedly, or just ignoring it—may come down to personality or breed.
除了生理上的原因外,汪星人对电视的反应也有可能“因狗而异”。到底是兴奋地到处跑、大声叫唤,还是高冷地不理不睬,这都有可能因为狗狗的性格和品种不同而产生差异。
