Dogs can tell

1.If you ever get the impression that your dog can “tel” whether you look content or annoyed, you may be onto something.

2.Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.

3.Researchers trained a group of 11 dogs to distinguish between images of the same person making either a happy or an angry face.

4.During the training stage, each dog was shown only the upper half or the lower half of the person's face.

5.The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face or images totally different from the ones used in training.

6.The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.

7.The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage.

8.“We can rule out that the dogs simply distinguish hetween the pictures bused on a simple cue, such as the sight of teeth,” said study anthor Corsin Muller.

9.Instead, our results suggest that the surcessful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.

10.“With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,” Muller told Live Science.

11.At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans.

12.“To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions, ” and this exposure has provided them with many chances to learn to distinguish between them, Muller said.

狗可以分辨

1.如果你觉得你的狗狗能“分辨”出你是满意还是生气，那你可能就对了。

2.根据一项新的研究，狗狗可能确实能够分辨出快乐和愤怒的人脸。

3.研究人员训练了一组11只狗，让它们分辨同一个人的表情，是高兴还是生气。

4.在训练阶段，每只狗只看到人的上半张脸或下半张脸。

5.然后，研究人员通过向狗展示与训练中使用的完全不同的人脸另一半或图像，来测试狗区分人类面部表情的能力。

6.研究人员发现，狗能够通过用鼻子触摸照片来识别愤怒或快乐的脸，这比人们预期的随机机会要多。

7.研究表明，这些动物已经学会了如何将它们在训练中所学到的人脸知识应用到测试阶段的新面孔上。

8.该研究的作者科辛·穆勒说:“我们可以排除狗只是根据简单的线索，比如看到牙齿，就能区分出照片的可能性。”

9.相反，我们的研究结果表明，成功的狗意识到微笑的嘴和微笑的眼睛是一样的，同样的规则也适用于愤怒的嘴和愤怒的眼睛。”

10.“通过我们的研究，我们认为我们现在可以自信地得出结论，至少有些狗可以区分人类的面部表情，”穆勒告诉《生活科学》杂志。

11.在这一点上，尚不清楚为什么狗似乎具备识别人类不同面部表情的能力。

12.穆勒说:“对我们来说，最可能的解释似乎是，这种基础在于它们与人类生活在一起，这让它们有很多机会接触人类的面部表情，”这种接触为它们提供了很多学习区分面部表情的机会。
