Research is now suggesting something dog-lovers have long suspected - man's best friend can tell the difference between our happy and angry faces. “狗奴”们一直怀疑对汪星人——人类最好的朋友——能够分辨我们快乐和生气的表情，日前一项研究认同了这一点。 Scientists at the Messerli Research Institute's Clever Dog Lab in Vienna trained dogs to associate pictures of happy or angry faces with a reward. 维也纳梅瑟利研究所“聪明狗狗”实验室（Messerli Research Institute's Clever Dog Lab）的科学家们，训练狗狗将笑脸或怒容的图片与奖励联系在一起。 In a subsequent test, the scientists showed the dogs images of human faces they had not seen in their training. 在接下来的测试中，科学家们给狗狗展示了一组它们在训练中从未见过的人脸图像。 This suggested that dogs could spot the difference between the expressions. 测试表明狗可以分辨出表情的不同。 "The main focus [of our research] is the big question of communication," lead researcher Prof Ludwig Huber said. “（我们研究的）重点在于“交流”这个重大问题，”研究小组负责人路德维格·胡贝尔（Ludwig Huber）教授说。 "How is it that dogs are so adapted to humans, and what's happened during the process of domestication?" “狗是如何适应与人类亲密相处的？在驯养过程中发生了什么？” |
